Pwr led on motherboard. Front panel of the computer: how to connect the power button, reset, connectors
The front panel of the computer consists of several connectors and indicators. Among them there is a reset button, usb ports, audio connectors, as well as hard drive activity indicators and a power indicator system unit. So, Power led is a chip that is responsible for turning on the system unit operation indicator. When you start the system unit, the power button lights up and lights up in a certain color, and when you turn it off, it goes out. So the Power LED connector is responsible for its glow.
How and where to connect Power LED?
On any motherboard, as a rule, in the lower right corner there is a special contact pad for connecting buttons and indicators on the front panel of the system unit.
Usually all her contacts are signed. On MSI motherboards it is labeled as JFP1. It looks like this:
JFP1 - this is how the area for the buttons and indicators of the front panel on the mat is labeled. msi boards
Almost always, the Power led connection occurs on the leftmost contacts located on the side of the key (places where, as it were, one contact is missing).

Moreover, when connecting Power LED, you need to take into account the polarity. The colored wire on the chip is “+”, black or white “-“.
On the contact track it is usually written where is “+” and where is “-“. If not, then “+” is the outermost contact, and “-” is the adjacent one.
It is also worth considering that Power Led comes in 2 and 3 pin versions. Made this for different models motherboards. On some of them, the Power LED connector is made in the form of a 2-pin plug, and in some of them, it is a 3-pin plug. Therefore, there is no need to connect 2- and 3-pin Power LED chips at the same time! One of them must be connected to the motherboard!

What if you connect the Power LED incorrectly?
Absolutely nothing bad will happen. It's just that the power button won't light up while the computer is running and you'll need to switch it the other way around.
In general, in order not to make a mistake when connecting the front panel connectors, you need to find the documentation on the official website or in the box from it and look there for the correct pinout of all connectors.
The system case is an important component of the entire computer. It is in the case that the “production workshop” of the entire computer is located, so to speak. It is in the case that the motherboard is installed, and the RAM, video card, processor and all kinds of wires and cables are already “hung” on it. Moreover, the power supply is located in a separate place inside the case, as well as HDD and drive.Modern cases look quite attractive, menacing, aggressive, unusual... The developers have enough imagination, which means that ordinary buyers can choose from a huge assortment. But not only do the current buildings have an attractive appearance, they also have “working” advantages. Such advantages are the USB connectors, as well as microphone and headphone connectors on the front of the case, which in turn means that we don’t need to crawl under the table and get to the back panel of the case every time we need to connect a flash drive. I think everyone will agree that these are, in principle, trifles, but still, it’s more pleasant to just insert a flash drive in front and start working.
But, unfortunately, there are cases when some parts of the computer case fail. We are talking about the notorious POWER button, which is available on absolutely every case. During long-term use, this button It may simply fail, for example, stop pressing, or vice versa, it will fall deep into the case, and no matter how hard you try, you won’t be able to turn on the computer. What to do in such situations? If you don’t really need a computer, then it’s better to call a repairman and wait with peace of mind until he repairs everything, paying him a certain amount of money for it.
If you need to use the computer quite urgently, then perhaps you should use the following advice.
First, you need to find a flat surface and carefully place the system unit so that the left cover is facing you, while you should not disconnect all the wires in order to complete everything faster, but you should make sure that these wires are not strained. Besides, prerequisite it must be that the computer is disconnected from the power supply, as they say, you never know. Next, what needs to be done is to remove the left housing cover. In modern cases, this usually does not require any additional great effort, so there shouldn't be any problems with this.
After removing the cover, a stunning picture will appear in front of you. You will see everything that at one time you paid a round sum for, and that usually works peacefully, making an innocent noise, and that which now does not want to “start up”. Our attention should be primarily focused on the multi-colored wires that run from the front of the case to the motherboard. There can be a lot of such wiring, and it’s not surprising, because there are also connected POWER buttons And RESET button, And USB ports, together with audio outputs. So, at the next step, we may need a little knowledge of English, which many received at school, because on the wiring themselves, as well as on the motherboard, near the connection of these wiring, it should be written what they mean. For example, you can take USB ports. On the motherboard itself, near the connection, there should be an inscription USB1, USB2, etc. This means that the wires connected to these connectors are nothing more than USB connection ports.
But we shouldn’t forget about our problem, and this means that we need to look for POWER postings(usually these are two wires woven together). Typically, the connectors to which the power or reset buttons are connected are located in the lower right side motherboard:
On most motherboards, these connectors are the same and consist of 9 pins arranged in two rows. Two last contact in a short row of 4 plugs are responsible for turning the computer on/off.
Here are connector diagrams for the most popular motherboard manufacturers.
MSI
AsRock
Asus
Biostar
Epox
Foxconn
Gigabyte
Intel
Once these two wires have been found, you should find where they are connected to the motherboard. Once the connection location has been discovered, it is worth carefully disconnecting these wires so that the small plugs are exposed.
That's it, now we're almost done. The final step is to turn on the computer; for this we need an ordinary stationery pen, preferably one that writes boldly. Once you have found such a pen, you can connect your computer to the power supply, and then carefully run the tip of the rod over these exposed needles. Or in other words, you just need to close these contacts. After these steps, the computer should come to life and the download will begin. If nothing happens, then you should repeat the procedure, but close these needles quickly enough.
Thanks to such simple steps, you can start the computer without special problems, however, this should not be neglected, and it is better to repair the start button on the case as soon as possible to avoid unnecessary problems.
Attention: Neither the author of this article nor the administration of this site bears any responsibility for possible problems that may occur when turning on the computer in this way. You will perform all of the above actions at your own peril and risk, and will be solely responsible for possible problems that are not described in this article.
One of important stages Assembling a computer involves connecting wires to the motherboard. Considering that there are a lot of different connections there, some points should be clarified. And although power supplies try to make all connectors intuitive for the user, sometimes problems arise.
Instructions for connecting motherboard wires (MSI, ASUS, ASRock, etc.)
Let us immediately note that the example below is not valid for all models and types of boards. It describes the general picture of connecting wires to the motherboard, but various small differences may always be present. We'll start by connecting the connectors. It is assumed that the motherboard is already screwed to the case and is ready for connection. Also, the power supply is already installed and screwed.
Connecting connectors
The very first stage is connection Power buttons, Reset on the body panel. We will also connect power to the LEDs, which serve as an indication of computer operation. These wires are directed from the front panel of the case, and they have different colors(yellow, red, etc.). At their ends there are connectors. Each of them has a special abbreviated marking. They need to be connected to the motherboard in sockets designated specifically for them.
It is worth noting that all connectors are protected from Not correct connection, so you are unlikely to be able to insert a connector into the wrong connector. It is important that the connection occurs smoothly, without any effort.
The connector that comes from the power button on the case is labeled M/B SW. Open the instructions for your specific motherboard and see where you need to insert it. It has no plus or minus, so it can be inserted either way.
The second connector is responsible for the reset button; it is labeled RESET SW.
There are also two more small single connectors with plus and minus indications and markings POWER LED+ and “-”. They are responsible for indicating the operation of the computer. It is important not to confuse the “plus” and “minus” positions, so be sure to check the instructions.
A hard drive LED without a plus or minus sign is labeled as an H.D.D LED. However, it must be set to negative with the white wire.
To be able to connect headphones to the case, and not to the motherboard, you need to connect the AUDIO connectors. The sockets on the motherboard are also marked as AUDIO, but before connecting, check the instructions.
The same thing applies to connectors for connecting USB interfaces. They need to be inserted into the sockets on the board marked USB. Let us remind you that if connecting wires to the motherboard Asus board(or other manufacturers) is carried out with great effort, that is, it is likely that you have the wrong socket or connector. The latter are protected against incorrect connection, and you simply physically cannot insert them into unsuitable sockets.
Most often, the connector sockets are located in the lower right corner - look for them there.
CPU power supply
Now we're talking about about connecting the wires to the motherboard that come out of the power supply. First of all, we connect the processor. The socket for its power supply is always located next to the processor itself, but we will not indicate the exact location, since it is individual for different models.
So, a 4-wire wire comes out of the power supply, which is connected to the processor socket. Most likely, it will be the only one on the motherboard, so it is unlikely that you will be able to insert the connector into any other socket. And yes, it has it too special key from incorrect activation.
Connecting the main cable
The main power cable for the motherboard is the largest. In addition to it there is a separate 4-wire connector. Take them together and connect them to the motherboard in one single existing connector. The connectors have special latches. Therefore, when connecting, make sure that this entire massive structure snaps onto a special protrusion in the connector itself.
RAM
Planks random access memory connect wirelessly. The contact method is used here. There are special slots with latches for RAM. They need to be moved aside and the slots (or slot, if there is only one) inserted in the only correct way due to the cut in the slot and on the bar itself. You need to insert the bar carefully, pressing lightly from above. The clamps should gradually converge and eventually snap into place.
Be careful not to press too hard, otherwise the motherboard will bend. Thus it is necessary to insert all the strips.
Connecting SATA and IDE devices
The hard drive is connected to the motherboard using a special SATA cable. It is usually red in color. The SATA cable has identical connectors at both ends. Connect one to the hard drive (there is also a key to prevent incorrect connection), and the second to the connector on the motherboard marked SATA 1. Usually there are 2-4 such connectors on motherboards. You can choose any one. After connecting the SATA cable, connect the power. In the rightmost hole (usually it is the rightmost) plug in the connector to which 4 wires from the power supply are connected.
Connects via IDE cable optical drive. But today modern computers are not equipped with disk drives because they are unnecessary.
Connecting a video card
The final stage of connecting wires to the motherboard is installing the video card. It is installed in the PCI-E slot, which is marked accordingly. In fact, you will not be able to insert the graphics chip into any other slot. Depending on the model of the motherboard, the video card is fixed or not fixed with a special clamp, but is always attached to the case with a screw.
Powerful video cards need additional nutrition from the block. If there is a power connector at the very end of the video card, then be sure to use it. After connecting, we are left with no loose wires from the power supply. However, they may remain if you do not have an optical drive installed. At this point, the instructions for connecting the motherboard wires can be considered complete.
Close the case cover and turn on the computer. Everything should work. But even if, when connecting wires to (or another brand), you forgot to supply power to any component, then there is nothing wrong with that. The computer just won't start, but it won't hurt anything.
USB ports usually come with the front panel for the system unit, or are installed as an addition to it. Let's look at installing USB ports into a computer using the example of connecting the front panel to the system unit. This panel will contain not only USB connectors, but also power and reboot buttons, and various indicators.
In addition, in any case, you will have to connect the front panel to the system unit, since without it you will not be able to use the computer normally.
Preparatory stage
Front panel, as well as additional USB connectors are installed on the motherboard after the main work on assembling and setting up the PC has been completed. Before installation, it is advisable to examine all the free connectors on the motherboard and the cables with which the front panel will be connected.
If you connect the cables to the wrong connectors and/or in the wrong order, you risk disrupting the functionality of the entire computer. It is advisable to find and carefully study the documentation for the motherboard and front panel, even if it is not written in Russian.
All elements on the motherboard and front panel have their own markings, so if you carefully study the documentation, you will not confuse anything. It is also worth understanding that the instructions described in the article have general character, since the features of your motherboard may differ from generally accepted standards.
Stage 1: Connecting indicators
If you are connecting the front panel, then this stage required. Those who connect an additional expansion board with USB connectors should pay attention to the design of this board. If it contains any indicators and buttons, then you should not skip this stage. If there are just connectors, then you only have to connect the cable responsible for the power supply.
Before starting work, disconnect the computer from power. Now we need to find special block located on the motherboard. Usually, it has a special designation and one of the signatures - "Front Panel", "F_Panel" or "Panel". It can also be found by location, since it is located as close as possible to the expected location of the front of the system unit.
Now let's look at the connecting wires that you may encounter both on the front panel unit and on the unit with additional USB connectors:
- The red wire is used to connect the on/off button;
- The yellow wire is responsible for the operation of the reset button;
- The blue cable is responsible for the operation of the system reboot/boot indicator;
- The power indicator depends on the green wire;
- To connect the panel to power, you need to use a white cable.
On some models, the functions of the red and yellow wires may change between each other, which can cause confusion. Fortunately, such models come across very rarely, and this feature is always written in the instructions.
Stage 2: Connecting the connectors
At this stage, you need to correctly connect the USB and audio connectors to the contacts on the motherboard. Cables and their connection points are marked accordingly. For example, the connection location is usually indicated by the inscription F_USB1, F_USB2 etc. It is worth understanding that there may be several such ports on the board. In this case, the order in which the cables are connected to them does not matter.
In the case of older versions of USB, everything is quite simple - connect the cables with special connectors on the motherboard and that's it. But if you connect USB versions 3.0 and higher, then it will have to be connected only to certain connectors. You can find out which ones exactly by using the documentation for the motherboard or board with additional connectors. Also on modern boards There are special symbols for connecting connectors version 3.0 and higher.
When all work is completed, try turning on the computer. If it turns on and works without problems, then connect the flash drive to one of the connectors you just connected. If the computer detects the flash drive, then everything is in order.
Connecting additional USB or front panel boards to your computer is not such a difficult task, but it requires careful attention and strict adherence to instructions.
It can be difficult for an inexperienced user to connect the motherboard. The abundance of wires, connectors, incomprehensible symbols - all this raises a number of questions. This article will discuss in detail the issue of connecting all other devices to the motherboard, starting with the power supply and ending with USB plugs from the front panel.
Connecting the front panel to the motherboard
Any case (system unit) has a front panel. Naturally, this is also necessary, otherwise the computer will not even be able to turn on. In addition, on the front panel there are the following (or similar in purpose) computer control devices:- computer power supply (start/shutdown) button (POWER SW) (see);
- computer restart button (RESTART SW);
- indicators of access to the hard drive (hard drive; H.D.D.LED or HD LED);
- sound indicators (SPEAKER);
- flashing light on the computer reset and power buttons (POWER LED +/-);
- USB ports.
To correctly connect all the wires and cables, you need to carefully study and translate the names to avoid erroneous actions. Or just use the computer assembly documentation. Everything is explained there quite clearly and down to the smallest detail. Moreover, specified information will relate specifically to a specific case and device, and not be generalized.
The place on the motherboard where these plugs need to be connected looks something like this:
In addition to the diagram with names, there are also color designations identical to the colors on the plugs. Cause problems this procedure should not. The black crosses in the picture are “keys”. They are located both on the connector and on the cables, but can have different shapes (depending on the manufacturer). It is worth connecting key to key, so that no mistake will be made when connecting devices. If there are no markings or they are difficult to see, you can try connecting the wires with the markings facing you. Also, the connectors sometimes have side locks. They can also act as a guide when connecting.
All plugs are connected all the way, but without using force. Pay attention to the guide elements for correct connection of devices (cuts, blocking parts, clamps, etc.).
Cables from USB ports are connected to the corresponding connectors. They may be named F_USB1, USB1, or simply USB. The number of such connectors may vary depending on the motherboard model, but often there are at least 2 of them.
Basic devices when connected to the motherboard
1. Securing the motherboard to the case. Usually there are 4 stands (sometimes more, but 4 will be enough), on which you need to bolt the motherboard. There can be no problems with this procedure, since the main and only condition is to be able to use a screwdriver. You need to tighten the bolts tightly, but without applying excessive force, so as not to break the motherboard. If the device stays stable in the case and does not “drive”, this is more than enough.Racks are needed to separate the motherboard from the case: they protect it from short circuits and help additional cooling and so on.
2. Nutrition. The first step regarding devices is to connect the power supply. Its installation on the case does not cause problems. Because a lot of the remaining cables will connect to other devices besides the motherboard itself. This will provide unhindered access to connecting other devices.
The power supply should be connected using a 24-pin connector (sometimes 20). It will not be possible to confuse it with other trains (there is only one of them). This connector looks like this:
The power supply socket is usually located on the edge of the motherboard. It is impossible to confuse it - this is the only connector of this width for two rows. No other device can be connected there. When connecting, you should do this carefully, pressing lightly until you hear a click so that the latch on the connector and the cable align. The remaining cables with clamps are secured in the same way.
All other cables from the power supply are completely different from each other, so there will be no questions about which cable is intended for which device. When in doubt, look for guides and markings. Or use the documentation for the purchased power supply/motherboard.
Under no circumstances connect a 20-pin cable to a 24-pin connector and vice versa. This will cause permanent damage that will be very expensive to repair. Rule number one is to always check whether a particular power supply will fit the motherboard model you are using before purchasing. This applies to any other devices except USB 3.0.
3. Winchester. Trail from hard drive It can be wide or not very wide. It all depends on the plug. There are two varieties: IDE and SATA.
The IDE cable looks like this:
The black connector (on the left) is inserted into the hard drive, and the blue connector (on the right) into the motherboard. This is what the place on the motherboard looks like where you need to insert the IDE plug from the cable (the blue connector, between the two black ones at the top and bottom).
Regarding the SATA cable, it is much smaller in size and is inserted into a connector marked “SATA1”, “SATA3”, etc. The designations can be anything, but always contain keyword SATA. It all depends on the motherboard model.
Drive, by the way, is installed on the board in a completely identical way. But its IDE cable is connected to a shorter connector (in the previous picture it is black, located just above the blue one). Otherwise, including the SATA connector, connecting the drive to the motherboard is identical to connecting a hard drive.
The SATA connector on the motherboard looks like this:
This is just an example, since such connectors can be of different shapes (vertical, horizontal) and located in different parts of motherboards.
You also need to connect the connector from the power supply, taking into account the guide elements. There are usually no problems with this. This completes the connection of the hard drive to the motherboard.
4. . Connecting a video card to the motherboard is not a complicated process at all, but there are specific tricks that you need to know so as not to break the latches. Most motherboards have clamps like these:
They are completely identical to RAM clamps. But sometimes there are not entirely obvious latches, the existence and operating principles of which every user needs to know about. Before connecting the video card, carefully study the operation of the clamps. If necessary, disconnect (or connect if the clamps mechanical type) device may have problems.
The video card connector itself is shown as number 8:
The blue vertical connector is where the video card is inserted. The piece protruding from the bottom is a standard retainer. It’s impossible to make a mistake, since you won’t be able to insert the video card the wrong way around due to the guide cut on the connector.
Then it is connected to the video card (for the vast majority modern models) additional source power supply in the form of a cable from the power supply. Often, this is a connector with 4 contacts, but there are also 2 wires with 2 contacts or 1 wire with 8 contacts. It all depends on the model and manufacturer of both the video card and the power supply. At the end, the cable from the monitor is connected to the outside of the system unit - the video card is completely ready for use.
5. Case fans(coolers). To connect these devices, simply secure them with bolts in the appropriate places (selected individually or following the documentation) and connect them to the motherboard:
Connecting the card reader to the motherboard looks like this:
Video instruction on how to connect the motherboard
The following video examines the connection of the motherboard in great detail, explains the meaning of the cables and explains a lot of additional information.The main thing in connecting the motherboard is to understand the symbols, guide the guide elements (hints; lack of contact, cut in the socket, false “pin” in the plug, etc.) and careful connection. If you follow these rules, then next time you won’t need any help connecting the motherboard - everything is so easy and simple.
