LED light sources are gaining more and more popularity, and there is no doubt that soon they will almost completely displace "competitors" - incandescent and gas-discharge lamps. Of particular convenience are LED strips - they are compact, flexible, provide a sufficient amount of light, they are easy to secretly place, directing them to the illuminated surface.
Most LED strips require low voltage power to connect direct current... Under normal conditions, special power supplies are used for this, which are purchased separately, taking into account the power of the generated backlight. But LED strips are very often used to equip a work (or play) place equipped with a computer. Is it possible in this case to do without purchasing a power supply, because there seems to be a constant current source with the required output voltage at hand? Yes, it’s quite possible. In this article, we'll just see how to connect an LED strip to a computer.
What is LED strip, and why is it connected to a computer
For those who are going to deal with LED strips for the first time - just a few words about their device, purpose, connection principle.
So, the LED itself is a compact semiconductor device. The term "diode" already implies that it is capable of passing current in only one direction. But the structure of a semiconductor crystal is such that when a current is passed, light energy is released in the form of emission of photons. In short, the LED starts to emit a luminous flux. In this case, heat energy is also partially generated, that is, it is necessary to take certain measures for adequate heat removal.
- The beginning of the large-scale use of these elements was laid by DIP-type LEDs. They can still be found often now, for example, in display systems of many household appliances, in garlands, in low-power lamps of old designs.
- Literally a revolution in the development of LED lighting was made by the appearance of LEDs of the SMD type. Such devices are already equipped with their own heat dissipation system (this role is played by a housing made of a special material). The emitted luminous flux has become higher, and this is against the background of a significant reduction in the dimensions of the LED itself. The elements can have a lens or simply be coated with a phosphor layer that sets the light temperature of the glow and eliminates the ultraviolet component. It is SMD LEDs that are currently the most in demand, and most tapes are produced with their use.
LEDs, depending on the crystals used and the phosphor coating, are available with a monochromatic white glow of various shades, and with a color (RGB).
Modern LEDs such as COB (left) and COG (right) can boast of even and powerful radiation- A new stage in the development of LED technology was the emergence of COB (chip-on-board) COG (chip-on-glass) devices. In fact, these are dozens of unarmed crystals placed on an aluminum (through a dielectric layer, of course) base-board or glass rod, which are then covered with a continuous layer of phosphor. The result is a powerful light source with a large emitting surface area. The luminous flux is emitted uniformly from the entire area of such a matrix or rod.
So, for the production of most modern ones, SMD elements of one or another standard size are used. The tape itself is, in fact, a flexible narrow circuit board, on which, in addition to LEDs, other elements necessary for normal operation are soldered. LEDs are located on the tape in one or two rows with a certain pitch, which predetermines the density of their placement - from 30 to 240 pieces per linear meter. The tape is sold by the meter - it can be cut into pieces of the required length, but only according to the marked marks located with a certain step (usually from 100 to 300 mm).
The back side of the LED strip is most often equipped with a self-adhesive layer, which simplifies its installation at the place of installation of the backlight. This adhesive layer is covered with a protective backing in the "stowed" position, which is removed immediately before installation.
We will not dwell in detail on the structure of LED strips and their classification - there is already enough information about this on our portal.
LED strips are a great "tool" for creating decorative or local lighting
With a creative approach, these lighting fixtures can almost completely transform the design of the room. About classification, order and schemes - read in a special publication of our portal.
Why might you need to connect an LED strip to a computer? Here it is possible to divide the question into a pragmatic and decorative component.
Let's start with pragmatics.
- The workplace at the computer for most users is a kind of individual zone in an apartment or house, in which most of their free time is spent. And for many, as they say in government circles, “self-employed citizens” is their main job. The working day for such people often imperceptibly spills over into the night hours. And partly in order not to bother the rest of the family, but also not to lose a comfortable environment, we have to think over the equipment of such a zone. This is a dim background illumination of the monitor area, since its work in complete darkness inevitably causes rapid eye fatigue and, in general, can negatively affect the user's vision.
Apparently, sufficient illumination of the desktop area is necessary if you have to make certain handwritten notes or use printed literature. An excellent addition is the LED strip located under the tabletop above the pull-out keyboard shelf.
- If we talk about decorative lighting, then everything here depends on the preferences of the owner. So, a fashionable trend (in the author's personal opinion - rather meaningless) is the internal illumination of the system unit, the installation of moldings or other luminous elements on it (inside it). Contour finishing (often with the effect of light and music) is practiced with LED strips of the entire worktop, monitor, speakers, etc. - everything that comes to mind of the "manager" of this area of the room.
Whatever is planned, LED fixtures require a connection to a power source. And if, as they say, there is a computer at hand, then it is quite possible to use the existing capacities.
A gaming computer is a reflection of the personality and preferences of the gamer himself, and therefore will be incomplete without a bit of bright colors. Yes, we know that not everyone likes backlighting, but it really is preferred by most users. On the other hand, there is a subtle difference between truly luxurious and overly fanciful lighting. It is not enough to simply install the appropriate components and LED strips and then turn it on.1 - computer power supply;
2 - Molex connector;
3 - a dimmer that allows you to smoothly adjust the brightness of the tape glow;
4 - LED strip.
In fact, the dimmer is connected to a break in the 12 volt power line, that is, nothing particularly complicated is foreseen.

The situation is somewhat different with connecting an RGB tape, which, in principle, cannot work normally without a special controller unit. But also - the scheme is not particularly complicated.
The difference is obvious. An RGB controller (item 3.1) is connected to the computer's power supply through the same Molex connector. And already from it to the RGB LED strip (pos. 4.1) there are four wires - common +12 volts and a separate wire for each of their color channels.
Video: Option for connecting the LED backlight of the computer system unit using the connectorMolex
Connecting several tapes to one source is also perfectly acceptable if some rules for tape lengths and total load are observed. More details about this are described in the article, which was already recommended above with the attachment of the corresponding link.
By the way, if the reader has a power supply unit from an old computer at home, and it is lying around, it can be easily adapted for LED backlighting. Moreover, as we have seen, each such unit has several outputs with Molex connectors.
Jumper that allows you to start a standard computer power supply without being connected to the motherboardThe only thing that will need to be foreseen. By itself, such a power supply unit will not start until it is connected to the motherboard. But this can be solved very simply - by installing a jumper on the MB connector. The contacts between which it is necessary to put such a jumper are shown in the diagram above. And in words - between the PS ON contact (most often a green wire is suitable for it) and ground (black wire, GND).
Find out which one in a special article on our portal.
Connecting the LED strip to the connectorUSB
This method can be used by those who, for one reason or another, do not risk climbing inside the case of the system unit on their own. stationary computer... In addition, this is the only option for connecting LED backlighting if the workplace implies only a laptop.
Let's make a reservation right away - the method is not very convenient, if only simply because the USB connector has a voltage of only 5 volts.
Soldering the USB connector on your own for later use in the backlight system is not so difficult. To do this, it is best to purchase a collapsible plug - they are presented in considerable variety in radio parts stores. And its pinout is well shown in the diagram above.
But for normal operation of the LED strip, five volts is not enough. This means that it is necessary to install some kind of converter that increases the voltage. In addition, there is also a limitation on the current load - no more than 500 mA. And this, in turn, means that if we raise the voltage from 5 to 12 volts, that is, almost 2.5 times, the permissible current will also decrease by the same amount. And it will be possible to seriously consider the possibility of connecting a tape with a maximum current load of only 150 ÷ 200 mA. As you can see from the table above, it turns out no more than one meter of the lowest-power LED strip - SMD 3528 with a density of 30 LEDs per linear meter. For other types of belts, very short lengths are generally permitted. However, for highlighting a small area of the table, and this is often quite enough.
The converter block can be purchased ready-made. Anyone who knows at least a little about electronics can be advised to assemble such a device on their own, guided by the diagram below.
The main element of the circuit in this case is a microcircuit - PWM controller LM2577. The general list of the rest of the elements, as you can see, is not large, and the scheme itself is not distinguished by its branching and high complexity.
The circuit is, in principle, highly versatile. And the precise adjustment of the output voltage is made by selecting the values of the resistors R1 and R2. You can be guided by the following formula:
Uout = 1.23 × (1 + R1 / R2)
Electrolytic capacitors at the input and output are responsible for smoothing out possible voltage fluctuations (ripples). Their capacity may be slightly higher than the specified value - this is not critical. Their working voltage is at least 20 volts.
The capacitor and resistor in the output circuit # 1 of the microcircuit set the operating frequency, and variation with the indicated ratings is not allowed. Equally stringent requirements for the value of the inductive coil between terminals No. 4 and No. 5.
Only a high-frequency Schottky diode of the specified rating should be used as a diode.
The assembled circuit, mounted on a self-made printed circuit board, does not take up much space. Alternatively, this type of converter is shown ready-made.
A ready-made voltage converter, which can only come up with some kind of protective caseWell, then - everything is simple. A piece of cable with a soldered USB plug is connected to the input terminals of the converter. And at the output, where 12 volts are removed, wires connected to the LED strip are connected.
It remains only to insert the plug into the USB socket of the computer (laptop, desktop hub) - and the backlight will light up.

So, the most convenient ways to connect the LED strip to the computer's power system were considered.
And one more important tip! When using any of the schemes, before carrying out a test run, do not be too lazy to once again carefully check the quality of the installation, the absence of short circuits and the correct polarity of the connection. A mistake can lead to dire consequences. It's not particularly scary to lose a piece of burned-out tape. It will be much worse if negligence leads to failure of the power supply or other computer devices.
In this article, we will introduce you to the various components and accessories that are used to illuminate the gaming system with new colors. At the same time, all its components will work as a single ensemble, giving it a magnificent appearance.
MSI Mystic Light Sync App
To get started, you need software that is flexible and functional, with which you can customize and synchronize the lighting of each component of your system.This is the kind of control the MSI Mystic Light app gives you. With its help, all illumination is regulated, from motherboard to LED strips, while the intuitive interface allows you to customize even very complex visual effects without the slightest effort.
* The Mystic Light 3 app can be downloaded from the following link:
Addressable RGB and non-addressable ARGB connectors
When buying backlit components, you will sooner or later come across these terms. Moreover, they hide not only different functionality, but also a very different appearance. This is why it is very important to understand the differences between the two types of connectors to which LED strips and other backlit devices are connected.The non-addressable connector (typically a 4-pin 12V) severely limits your color management capabilities. For example, it is impossible to make different sections of an LED strip connected to such a connector glow in different shades.
In contrast, addressable connectors (usually 3-pin 5V) are equipped with a control circuit (microchip), thanks to which they offer much more flexible adjustment.
As a result, it is possible, for example, to make an LED strip light up simultaneously in several colors, including synchronously with other similar strips connected to the addressable connectors.
Next: select the main components
Before you start choosing accessories, you need to choose the right PC parts. Without a solid foundation, backlit components cannot work harmoniously, which is why the motherboard and chassis are just as important to a backlit configuration as they are to any other PC.Motherboard:
As the foundation for our PC, we chose the MPG Z390 GAMING PRO CARBON motherboard, which not only has special gaming features to improve the gameplay, but also allows you to connect accessories and backlit components. In addition to its built-in backlighting, the board offers a JRAINBOW connector (addressable) and two non-addressable 4-pin RGB connectors. In addition, it supports the Corsair addressable controller, which allows you to control the lighting of Corsair components through the MSI Mystic Light app.* Note: Devices with addressable illumination must be connected to JRAINBOW connectors, otherwise they will work as non-addressable (light with one color).
Body: MPG GUNGNIR 100
If you want to build a backlit gaming PC, then the case should be given special attention. It should not only look good on its own, but also provide easy access to the backlight adjustment. This is exactly what the MSI MPG GUNGNIR 100 model is.On its front panel there is a button that allows you to instantly change the visual effect of the backlight, as well as control its brightness. A pre-installed fan with addressable lighting is already connected to it and ready to obey your commands.
In addition, the scope of delivery includes a special hub to which you can connect up to eight addressable LED strips. Thus, you get ample opportunities to illuminate the computer at your discretion, both right now and in the future.
5 best backlit PC components and accessories!
So, with the basic stuff sorted out, we can now move on to the additional elements for our build.Memory modules: RAM
There are currently many backlit memory modules available to support a variety of visual effects. This is why they are an indispensable element of any colorful computer.▼ HYPERX PREDATOR DDR4 RGB
Case fans and CPU cooler
The case fans and the CPU cooler are some of the most noticeable elements of a computer, especially if the case has a tempered glass panel like the MSI MPG Gungnir 100.The backlighting of these components will immediately catch your eye. Therefore, a modern processor cooler with full-color backlighting is an integral part of any gaming computer.
When choosing case fans, do not forget about the actual cooling in the pursuit of color. For our build, we recommend the addressable backlit fan. It will be a great addition to a similar fan already pre-installed in our chosen case. In addition, it will be able to work in sync with other components, creating uniform visual effects.

Video card bracket: ATLAS MYSTIC ARGB
Bracket ATLAS MYSTIC ARGB - great way protect your graphics card while adding even more color to your gaming PC. Without such support, a massive device will sag, which sooner or later can lead to damage to the graphics slot. The bracket is equipped with addressable lighting, which will be a great addition to common system illumination.So, this accessory is the protection of components plus additional paints in the appearance of your computer.
RGB LED Strips
Use LED strips to disperse the darkness! Place them in areas of the chassis that are not covered by the illumination of the main components and accessories to achieve a harmonious illumination of the entire computer system.There are many ways to place ribbons, and it all depends on your personal preference. To create atmospheric lighting, make them not directly visible. Place the ribbons facing different surfaces to diffuse the light from them.
If the LED strips are visible right through the transparent side panel of the case, it looks too pretentious, so this option will not be ideal.
RGB Backlit Peripherals
When it comes to peripherals, you have the widest selection of backlit devices. However, as we strive for comfort and consistency, we will only be looking at gaming mice, keyboards and headsets whose backlighting can be adjusted using the MSI Mystic Light app. Meet to complete list you can, but below are our recommendations:- Gaming Headset: The headset features full color backlighting that can be controlled via the MSI Mystic Light app and is Hi-Res Audio certified for fantastic sound quality.

In this article, we will consider the backlighting of the computer's system unit as one of the most common types of modding.
In the first part of our article, we will look at installing the backlight in various parts of the system unit. In the second part, we will consider the options for connecting the backlight.
1. External lighting.
This type of backlight allows you to see all the main external components of the computer in the evening.
1.1. Backlighting of the front of the system unit with LEDs
Diodes used in this paragraph
To begin with, we solder the LEDs to the extreme ends in series, and also solder 2 additional wiring 30 cm each to them.
Select the location of the LEDs and mark it with dots.
In our case, this is the place, next to the DVDRom, where all the inputs are located. Therefore, I had to remove the DVDRom, as well as the protective shell.
.jpg)
We drill holes. We insert a chain of LEDs into these holes
1.2. External illumination of the lower part of the system unit.
This type of lighting provides for the presence of legs on your system unit, therefore it is suitable for experienced modders.
The best way to do this is to use an LED strip.
The tape is easily cut with ordinary scissors into lengths divisible by 5 cm. The lengths are easily connected with wires. In this article, we will cut the tape into several pieces for clarity, but you can use 4 pieces around the perimeter of the system unit.
We fasten our structure to the body using a self-adhesive tape layer and connect
Used tape from this section. a complete assortment with all kinds of colors.
2. Illumination of the inside of the system unit
It is carried out in several ways.
2. 1. By means of LEDs ().
We sequentially solder the LEDs. Solder the long leg (+) of the first LED to the short leg (-) of the other LED.
We solder the wires to the remaining two free legs.
We place the LEDs in the system unit. It is best to place them on the bottom and back wall.
2.Using pieces of LED strips.
With LED clusters, you don't have to solder each diode separately.
LED clusters are interconnected by two wires 5 cm long, so that they can be placed both close and at a certain distance. They are inserted into the holder and placed along the perimeter of the inner part of the system unit using double-sided tape.
Clusters must be placed so that they do not interfere with the installation of expansion cards, drives and other mods. If there are not enough wires between the clusters, you can lengthen them yourself.
.jpg)
After installing the clusters in their places, it remains only to connect the power.
Clusters can be quite expensive and there is no point in using them in most cases. You can take it, cut it into pieces of 5 cm. As a result, you get the same thing, only for a smaller amount.
3. Backlighting with LED strip.
The installation principle is similar to the installation of LED clusters, but significantly. The tape has 2 terminals on each side for connecting wires, and is also equipped with a self-adhesive surface, thanks to which you can install the backlight without using additional devices. Before fixing the tape, it is better to degrease the surface. 
4. Illumination of the cooler
This is the only type of backlight where we will take wires powered from the cooler itself as a power source in order to do without unnecessary wiring.
To begin with, we take 2 LEDs and solder them according to the standard scheme.
We glue the LEDs on the inside of the cooler. We take power directly from the cooler.
Now it is enough to connect the cooler and the LEDs will work simultaneously with it.
Backlight connection.
1.To the 4-pin molex connector
The 4-pin molex is the most common power connector in a computer. This connector contains four contacts: +12 V (most often yellow wire), +5 V (red wire), as well as two ground contacts (black). When connecting the backlight to a 4-pin molex, you can choose exactly where to connect the LEDs, to 12 or 5 volts. 
In our case, you need to connect to a 12 volt source.
Before connecting, you must first check with a multimeter the correspondence of the selected contacts, and determine the polarity. After that, you need to solder a 120 ohm resistor to the positive contact, from which, in turn, we take another wire and connect it to the "plus" of our backlight. The minus is soldered to the ground pin of the molex connector. After that, we carefully insulate the wires and close them with a heat-shrinkable tube.
For example, let's connect a single LED.
2. To the 3-pin connector
3-pin connector - a standard connector for connecting fans in a computer and similar connectors are often superfluous. Therefore, it is reasonable to use them to connect the backlight. The 3-pin connector has 3 pins: + 12V, ground, and a third pin that is used by the fan speed sensor.
The connection principle is identical to the connection to the 4-pin connector. We also use a 12 volt pin and a ground pin. However, it is important to remember that 3-pin connectors are for connecting fans and. therefore, cannot withstand the loads of the 4-pin connector. But for connecting LED backlighting, it will still work. Also, here we need a 220 ohm resistor. Otherwise, there are no differences. We carry out the same operations as in the first case.
3. To the USB connector.
USB is a data transmission connector and is usually used for this very purpose, however, in addition to data, the USB connector also transmits voltage and can be used to power various devices. The USB connector has four pins: two of them are responsible for data transmission and two more are responsible for voltage transmission. The USB connector has a 5V voltage supply up to 500mA. There are 2 types of USB connectors: 4 x 12 mm and 7 x 8 mm.
The differences between them are only in form. There is no difference between the two to connect the backlight. In our example, the first variant of the USB connector is used.
This type of connector requires an 82 ohm resistor. As in the first two cases, we determine the polarity and solder the resistor to the "plus". We also attach the "minus" to the "ground" contact. We close all connections with a heat shrink tube.

Can be connected to a computer.
There is also an elegant solution - the use of flexible neon! In this case, a neon cord of different colors is pulled along the stubs and half connected to the inverter.
Three things prompted me to write this article. Firstly, for the first time in my 10-year career, I attended Computex, which takes place every summer in Taipei. Regular readers who have come out on our site have probably noticed that at this event a huge amount of all kinds of computer equipment, equipped with backlighting, was presented. The stands of large and small manufacturers literally burst from the accumulation of colorful and bright system units, components and peripherals.
Secondly, at Computex 2018, there were many assemblies in the Quadstellar case, which will be discussed below. That is why, when Deepcool offered us to test their device, an attempt was made not only to review the case, but to try to independently "make" the system with big amount components equipped with RGB-backlit - and at the same time identify various features and the nuances that a novice user may encounter.
Thirdly, it must be admitted: every day more and more components equipped with RGB backlighting appear on the computer market.
At the same time, there are skeptics among our readers who believe that backlighting and other modding elements in a computer are useless tinsel, because the main criteria for selecting components are performance, reliability and functionality. Indeed, these qualities in any PC are at the forefront and there is no point in assembling an RGB-backlit system for the sake of only one backlight. Let's not divide everything that happens in our life only into white and black: in this article we will show that a computer with RGB backlighting can be both productive and reliable, and functional, and, finally, beautiful.
⇡ Choosing iron
In fact, all of the above is first tip when assembling a backlit system: first, we decide on the tasks that the system will perform, and only then we select components with elementsRGB... In this regard, we are obliged to act quite straightforwardly: all components in a PC must be compatible with each other; they must work stably and cool effectively. If you are new to this business, then I recommend that you first study the latest issue of the "" section, which considers 12 assemblies that are relevant at the time of the release of the material.
Even in the introduction, I announced that the main character in today's "story" will be the Deepcool Quadstellar. This model has an unusual appearance and design. A small survey revealed that the device evokes various associations in people. So, during testing, Deepcool Quadstellar was called a flower, a spaceship, a distant star and even a turtle. A little later I will tell you more about the design features of this device, but for now I will note the main features inherent in cases that are suitable for assembling a computer with RGB backlighting.
Throwing aside the unusual look of the Deepcool Quadstellar, you can notice the features inherent in a case well suited for assembling a bright system - the presence of a side window made of tempered glass. There are a lot of such devices on sale in 2018. For example, we recently tested a model. I ask you to use a case with a side wall made of tempered glass for one reason - such devices look nice. Unlike "crafts" equipped with plastic windows. In addition, as a rule, tempered glass has a slight tint, which dims the backlight and makes the dust accumulated in the case less noticeable.

The computer case does not need to have its own backlight. In my opinion, this is purely a matter of taste, since not all users, for example, like it when RGB elements shine directly in the face. At the same time, the front panel of the Deepcool Quadstellar is equipped with RGB cross lighting. All its components are configured using special software (we will talk about it later) or using AURA Sync technology - for this, the Deepcool Quadstellar fan and backlight control unit must be connected to the ASUS motherboard.
More often than not, a computer case is equipped with RGB fans. There are enough cases on sale equipped with monochrome backlit fans. The second type of device, in my opinion, is not very interesting. And if you really like the case, then it is easier to replace the impellers in it with models that have the ability to adjust RGB.
Thus, a visit to the Regard computer store revealed that you can find on sale "Carlsons" from such manufacturers as Cooler Master, Corsair, Deepcool, ID-COOLING, Aerocool, NZXT, ENERMAX, Thermaltake and Xilence. Models with true RGB support (16.8M customizable colors) share similarities. For example, these devices have an external controller to which fans are connected. Usually it is small in size, allowing it to be hidden in the HDD cage or fixed on the enclosure wall. The controller itself is either connected to the motherboard, or the backlight is configured using an external control panel.
This design, which is quite natural, leaves its imprints. Second tip: when connected a large number fans use a spacious case... In particular, you will need to use one or two or three (depending on the manufacturer) controllers, which will have to be fixed somewhere. Either way, an RGB fan is always extra wires and extra space.
It is important to understand that fans from different manufacturers are not compatible with each other. Take a look at the photo above showing Deepcool, Thermaltake and ENERMAX impellers. It is noticeable that these devices lack the standard 4-pin connector. At the end of the wires, their own proprietary contacts are brought out, which are connected to the control unit that comes with the kit. And the control unit itself, as I have already noted, is connected to the motherboard - it can be either an internal USB 2.0 connector or special connectors for connecting RGB tapes. So, when choosing case fans, it is better to use models from the same manufacturer.- so it sounds third tip... The controllers are designed in such a way that the number of fans can be increased. For example, in this article I used the ENERMAX UCTBRGB12-BP6 wind turbine kit consisting of six 120mm fans. However, 8 turntables and two RGB strips can be connected to the controller.
The ENERMAX UCTBRGB12-BP6 fan kit does not work well when used with a CPU cooler. Together with the impellers goes remote control, with which you can adjust the backlight, as well as adjust the speed. There are no other ways to change the number of revolutions of these fans, so such air blowers are poorly suited for processor cooling systems. My to you (fourth) tip: take fans withRGB backlit, speed can be adjusted inBIOS of the motherboard or using the software that comes with the fans, and not just using the remote control... A "lazy woman" can always get lost, and it is not always convenient to use such a device. Yet we are not building a backlit system for the sake of just the backlight - the computer must be fully controllable.
However, the ENERMAX UCTBRGB12-BP6 fan backlight is compatible with ASUS, ASRock, MSI and GIGABYTE motherboards.
Backlit fans are not a gimmick. Such devices were on sale before, but you had to use either a control panel or a switch located directly on the Carlson body. Nowadays, controlling RGB fans is much easier.
I think regular readers are familiar with names like MSI Mystic Light Sync, ASUS AURA Sync, ASRock RGB LED and GIGABYTE RGB Fusion - this is the list of technologies that are responsible for backlight synchronization various devices connected to the motherboard. Therefore, if the fans support one or another technology, then their backlighting can be controlled using the proprietary software of the motherboard manufacturer. Within the framework of the article, we will study in detail the work of the MSI Mystic Light Sync technology and see what we got out of it. To do this, I asked the Russian representative office of the company MSI motherboard board and video card equipped with RGB backlighting. As a result, the coolest models Z370 GODLIKE GAMING and GeForce GTX 1080 Ti GAMING X TRIO arrived at the editorial office.

Leading manufacturers also produce backlit video cards. You may have met the GeForce GTX 1080 Ti GAMING X TRIO. The video card is equipped with a TRI-FROZR cooler with three TORX 2.0 fans. According to the manufacturer, these impellers create 22% more airflow while remaining virtually silent. Low volume, as stated on the official MSI website, is also ensured through the use of double-row bearings. Note that the radiator of the cooling system includes six massive heat pipes, and its fins are made in the form of waves. According to the manufacturer, this shape increases the total scattering area by 10%. The radiator also comes into contact with the elements of the power subsystem. MSI GeForce GTX 1080 Ti GAMING X TRIO memory chips are additionally cooled with a special plate.
According to the technical specifications, MSI GeForce GTX 1080 Ti GAMING X TRIO has three operating modes: Silent Mode - 1480 (1582) MHz for the core and 11016 MHz for memory; Gaming Mode - 1544 (1657) MHz for the core and 11016 MHz for memory; OC Mode - 1569 (1683) MHz core and 11124 MHz memory. By default, the video card has game mode enabled.
As you can see from the photo, the adapter is equipped with a massive backplate that increases the rigidity of the structure. The back of the video card has an L-shaped strip with built-in RGB lighting. With the help of the same Mystic Light program, we can separately adjust three glow zones, as well as two rows of symmetrical lights in the form of dragon claws that frame the cooling fans.
If we had used a video card of another manufacturer in the system, then it would not have been possible to adjust its backlight (if any) in the Mystic Light program. That is why the motherboard and video card (if equipped withRGB backlit) must be from the same manufacturer — sixth tip.
And then everything is simple: the device has support for one or another backlight synchronization technology, which means that you can easily configure it in the software of the motherboard manufacturer. This applies to fans, RAM, video cards, power supplies, etc. Even more - now we can synchronize the work of the backlight not only of the hardware installed in the case, but also of other peripherals: a keyboard, mouse, headset and even a monitor.
Probably the easiest thing to do is decide on RAM. RGB kits do not require any additional wires or controllers. We simply purchase the modules we need, install them and configure them in the motherboard software. The photo above shows the Crucial RAM kit, but you will find RGB memory from manufacturers such as ADATA, Kingston, Corsair, KLEVV, Patriot, GeIL and G.Skill on sale - it seems that no one was left on the sidelines. Seventh tip: just make sure the device is compatible with motherboard and with backlight timing technology... As practice shows, MSI, ASUS, ASRock and GIGABYTE backlight synchronization technologies are the easiest to work with.
The Crucial BALLISTIX TACTICAL TRACER comes with its own software. In case the RAM will be used with a motherboard that does not support sync technology. Other memory kits have similar software functionality.
Finally, the system looks best when all four (or eight) DIMM slots are occupied by memory modules.
Now it's time to start assembling your computer.
⇡ We assemble the system in the Deepcool Quadstellar case and connect the backlight
Now that we have decided on the choice of components, it remains to put everything together. Deepcool Quadstellar is an unusual case, but even working with such a device, you just need to follow all the steps described in. In fact, we are dealing with a Full Tower case, made in a futuristic style. Just in case, below are specifications Deepcool Quadstellar.

The chassis is entirely made of aluminum. Visors on the front panel are made of glossy opaque plastic, and four removable windows are made of tinted tempered glass. The windows are attached to the body with magnets. By the way, in this way, without disassembling the device as a whole, it is very easy to clean the components from dust.
The front panel of the case reminds me personally of a blossoming flower. By the way, the “petals” of Deepcool Quadstellar open when turned on, and this action looks very bewitching. Dust-collecting filters "hide" behind the blades themselves in the body, which can always be removed and cleaned. And behind the filters are four Deepcool TF120 120mm blowers. They don't have backlighting, by the way. The minimum rotation speed of "Carlsons" is 500 rpm, and the maximum is 1500 rpm. Another fan - the fifth (exactly the same TF120) - works for blowing and is installed in the back of the section with storage baskets. It is not possible to install other larger case fans (for example, 140mm) in these slots.

As you can see from the photographs (and by the name), the interior of the Deepcool Quadstellar is divided into four sections. If you look at the hut from the back, you will see that the upper left compartment is intended for installing video cards - graphics adapters up to 380 mm long are supported. The section will fit video cards of any thickness. If you get one more flexible cable and an external PCI Express x16 connector, you can even install two video cards there. However, I do not recommend doing this - two video cards, even if there is a case fan working for blowing, will be cramped in such an impromptu "bunker". If you do not use a flexible cable, then the video card can be installed directly into the expansion slot of the motherboard. Typically, the unused upper section is occupied by modders with a reservoir with an SVO fluid.

Drives are installed in the upper right compartment. Deepcool Quadstellar has eight baskets at once for installing 3.5-inch hard drives and two more bays for installing 2.5-inch storage devices. In one of these pockets you can. Below is the GamerStorm inscription - it is also highlighted and also configured in the QuadStellar software.

Note that the cages for 3.5-inch HDDs are equipped with rubber pads. Yes, you have to work with a screwdriver to screw eight drives at once. Unfortunately, if you get rid of all the baskets, then, alas, you will not be able to use the empty upper compartment of the case.

The power supply is installed in the lower right section. Deepcool Quadstellar supports sources up to 300mm in length. Immediately, I note that our "spacecraft" has plenty of free space - therefore it is not at all surprising that so many colorful projects with custom CBOs and illumination, created on the basis of this case, were presented at Computex. And yes, a backlit power supply unit will look quite harmoniously in Deepcool Quadstellar. It is a pity that I did not have such a model at hand.
The bottom left section holds the motherboard. The chassis supports all popular form factors, including E-ATX. Just keep in mind that the large board will block the cable routing holes.
At the beginning of the article, I noted that the front panel of the Deepcool Quadstellar is equipped with a backlight. The "Life-Giving Cross" is divided into four zones, which are configured separately - I will talk about this later. The Gamer Storm logo is also highlighted, the rectangular rhombus includes the power key. On the upper left side of the case there are two USB 3.1 Gen1 ports, as well as 3.5 mm jacks for connecting headphones and a microphone.
The package included a colorful and detailed manual assembly, as well as all the necessary mounting tools, including additional adapters for connecting fans and lighting. Conveniently, all the cogs are arranged in sachets and signed.
In order to start assembling the PC, it is necessary to partially disassemble the case, namely to remove the four metal walls from the compartments. After that, I suggest starting the assembly with the installation of the water cooling system, the motherboard and the power supply.
The best place to start is by installing a CPU cooler. Look, the maximum CO height in Deepcool Quadstellar should not exceed 110 mm, so it makes sense to use a liquid cooling system with such a case. The device supports one 360mm and one 240mm radiator. In the first case, the CBO element is attached to a plate attached to the front panel; in the second case - to the special slide provided in the lower part of the compartment for installing the motherboard. Larger radiators will not fit into the case. The grill under the skids is equipped with a removable dust filter.
To write this article, my choice fell on an unattended CBO with a 240 mm radiator. First, I removed the metal plate, unscrewed the existing Deepcool TF 120 fan and fixed the dropsy radiator in it. Then I secured the plate back to the front panel with two screws and three thumbs. After this procedure, you can start installing the motherboard, but before that, do not forget to fix the central processor and part of the LSS fastening mechanism in the socket.
Our system uses the MSI Z370 GODLIKE GAMING motherboard, it is made in the E-ATX form factor. In general, there is nothing critical about this, however, the PCB blocked the holes for routing the power supply cables. After installing the motherboard, we fix the water block on central processing unit and proceed with the installation of the power supply.
There will definitely not be any problems with installing the power supply. Free space Behind the barrier wall, Deepcool Quadstellar abounds. At the same time, the chassis is designed so that the length of all the main power supply cables is sufficient to connect the motherboard, video card and drives.
After installing the power supply, I set about connecting all the wires, including the connectors from the I / O-panel of the case.

By default, all Deepcool Quadstellar case fans are already connected to the control unit. There is an information plate next to it, which will definitely come in handy if you want to reconnect the impellers in any way or install other blowers. Personally, I did not touch anything, but simply reconnected the existing wires more carefully.
By the way, a thermocouple comes from the control unit, which can be fixed on any part of the case. The temperature reading from this sensor will be displayed in the QuadStellar mobile app.
After installing the CBO, the motherboard and the power supply, as well as connecting the body controls and interfaces, it remains to connect the drives, the video card and, in fact, the backlight.
There will be no problems with installing hard drives: we fix the HDD in the basket - we connect the wires to it. Install the video card last. I decided to put it in a separate section - this way the assembly looks much more brutal.
There are five RGB backlit elements in our assembly. With the motherboard, video card and RAM, everything is clear - for RGB to work, there is no need to connect any wires. Therefore, all that remains is to connect the backlit fans and ribbon.
At the bottom of the MSI Z370 GODLIKE GAMING, there are two tape connectors: JRGB for 12V tape and JRAINBOW for 5V addressable tape. I decided to install a couple of ENERMAX fans on the dropsy. Plus they are fully compatible with Mystic Light technology. Placement of the controller was not difficult: it comes with double-sided tape, and the Deepcool Quadstellar is full of free space. The fans have their own proprietary connector through which they are connected to the controller. The controller itself is connected to the JRGB connectors of the motherboard and the MOLEX power supply.
That's basically it. The MSI Z370 GODLIKE GAMING was bundled with a splitter that allows two tapes to be connected to one JRGB connector at once. It is important to connect the tape correctly. For this, an arrow is shown on the connectors. At wrong connection The RGB tape will simply burn out. The same goes for addressable 5-volt tapes.
A well-known method of lighting rooms is LED lighting using LED strips. It has several advantages over other light sources. Efficiency, ease of attachment - this makes it convenient for use in any premises and in certain areas, whether it be the case of the system unit, the back of the monitor or the backlight for the computer. How to connect LED strip to computer in different ways?
What is the backlight for the computer space for?
The personal computer has long been an important part of any apartment or other home. People spend a lot of time at the monitor screen, and it is necessary to make this workplace comfortable and convenient. In addition, the lack of lighting near monitors and TV screens entails health problems, specifically with vision.
It is important to provide screen backlighting at night so that the bright light from the monitor does not stand out from the surrounding environment and does not tire the user's eyesight. For this purpose, an LED strip is suitable, which will make the room more beautiful and more modern, visually highlighting the computer space. In addition, you can use it as a New Year's decoration or as a decorative backlight in the system unit.
Properties and principle of operation of LED strip
LED strip is often used due to the following advantages:
- great glow;
- long service life;
- efficiency in power consumption;
- flexibility, the ability to install in any structure;
- ease of installation on any plane due to the adhesive surface;
- the ability to adjust the length of the tape (cut and grow as needed).
It should be borne in mind that the LED strip is a low-voltage equipment, that is, it requires a voltage of 12 or 24 V (volts) to power it. In the home electrical network, the voltage is 220 V 50 Hz, so this lighting element will be connected strictly through the power supply, selected depending on the power consumption of the tape. There are also led lamps for a voltage of 220 V, they are connected directly to the outlet, but they are not suitable for lighting a computer. The best option for PC backlight is 12V.
You can connect any tape to a PC, but before buying it in a store, you should decide on several characteristics for further effective use:
- diode crystal density;
- mono or tri-color glow;
- length;
- water resistance class;
The total power of the lighting fixture and the choice of the power supply depend on the density of the diodes. There are strips with a density of 30, 60 and 120 LEDs per meter. The length of a conventional coil is 5 meters, it will be enough to illuminate one PC. For home use, a low moisture resistance class of 20IP is sufficient.
This light source works like a printed circuit board. The LEDs are soldered into a rubberized substrate in series and are powered from the power supply. It is important to choose the right power supply unit, since the operating condition of the tape depends on it.
Materials and tools required for work
To connect the led strip, the following tools and materials are required:
- LED strip of the required length;
- power unit;
- soldering iron;
- solder plus rosin;
- scissors;
- electrical wires with a cross section of 0.75 mm;
- insulation stripping tool;
- side cutters.
Connection diagram of a conventional tape
It is proposed to consider in detail the connection diagram of a standard tape 1 meter long to a computer. The tape consists of LEDs of the SMD 3528 type, you can cut it off every three diodes. To complete this task you will need:
This method is well suited for backlighting a system unit with a transparent case cover to decorate "cool iron".
RGB tape connection diagram
Multi-color ribbon can be connected to PC using RGB controller. This is a specialized device designed to control the glow of three colors of diodes:
- green;
- blue;
- red.
As a result of mixing the glow of the three colors, different shades of light are obtained. Four wires are required to connect the multicolor diodes. Paired with a controller, you can use a remote control to control color reproduction from a distance. The circuit uses a 12 volt supply and a tape length of up to 5 meters. To simplify the assembly of the circuit, you can purchase ready-made detachable connectors designed for strip lights.
Mains connection via power supply
The converter reduces the mains voltage from 220 V to 24 V or 12 V. PSUs can be different:
Converters from a laptop, from a charger for a phone, from personal computer... It is important that the current supplied from the PSU is higher than that consumed by the tape. One meter of the luminaire consumes 0.4 A, respectively, 5 m - 2 A. The power supply current is indicated on the body. Calculations are not difficult to make. When connecting the luminaire to the power supply unit, it is important to observe the polarity, otherwise it simply will not turn on.
You only need to connect the wires of the corresponding color. You can add a switch to the circuit for ease of use. It is possible to use a dimmer to control the brightness of the glow. An external power supply unit is not suitable for lighting the system unit, but is more suitable for lighting a computer desk or monitor.
Mains connection without power supply
All factory made LED luminaires are powered by a power supply. Using a special circuit, you can connect them directly to a 220 V 50 Hz network.
To do this, you need to do the following:
- Cut the tape 5 meters into 20 pieces (at least three diodes).
- Connect diode bridge to convert AC to DC.
- Connect a 5-10mF 300V capacitor to eliminate flicker.
- Connect 20 parts together in series, connecting minus to plus, and plus to minus.
By insulating all exposed contacts, you can plug in and enjoy the backlight.
USB connection
The method of connecting the lamp via USB deserves special attention, since it is suitable for a laptop (the only option for backlighting) or when there are no free power connectors in the computer. The voltage in the USB socket is 5 V, and the load current does not exceed 0.5 A. This is not enough for a lamp that requires 12 V. You need to purchase or make a 5 V to 12 V converter and power it from USB.
It should be borne in mind that an increase in voltage by 2.5 times entails a decrease in current by the same amount, that is, up to 0.2 A (up to 0.5 meters of tape with a density of 60 LEDs per meter). If you exceed the load current, you can damage USB port... To connect LED lamp via USB you need:
As you can see, you can effortlessly connect the LED strip to a computer or to an external power supply to decorate your workplace. You can choose the most suitable method for everyone. The main rule is not to exceed the current load on the power supply or on the USB port. To successfully connect the LED backlight, you should follow the instructions above and do not be afraid to do something with your own hands.
