php editor Baicao will introduce to you how to connect the power cord of the computer motherboard. When assembling a computer, correctly connecting the motherboard power cable is a crucial step. The motherboard power cord is responsible for transmitting power supply to various components on the computer motherboard, such as CPU, memory, etc. Proper wiring ensures proper operation of the computer and avoids damage to the hardware. The wiring method is relatively simple, just plug the power cord into the corresponding interface on the motherboard. Let's take a closer look at the specific steps of this operation.
1. CPU power supply interface. The CPU power supply cable socket is usually in the upper left corner near the U. The 8PIN power supply cable of the CPU will be marked, but many people are easily confused with the 8PIN of the graphics card. In fact, it is easy to identify. Generally, the CPU is composed of 4 4 and 8, and the graphics card It is 6 2 which makes 8. If they are all 8PIN, there will also be text on the surface.
2. Mainboard power supply interface. The motherboard interface is very easy to identify. Find the 24-pin interface and insert it in the correct direction.
3. Graphics card power supply interface. The power supply interface of the graphics card is similar to that of the CPU. You only need to plug in a few interfaces on the graphics card to fill it up.
4. Hard disk interface. The hard drive power supply cable is generally a flat SATA port, and the SATA power supply cable is also designed to be fool-proof. If it is in the wrong direction, it cannot be inserted normally. There are generally two ways to identify the direction, one is the corner of the interface, and the other is the empty port of the second interface. , and the motherboard header of the SATA cable is also the same. Just connect the hard drive power supply cable and the motherboard header.
5. Chassis Fan Interface: Some chassis come with their own fans, or some players purchase and install a chassis fan. The power supply line of the chassis fan is usually a large 4D port. The direction of the large 4D port is easy to identify and can be directly plugged into the power supply. Just interface.
6. Audio and USB interfaces
The front audio and USB interfaces have corresponding interfaces on the motherboard, and there are also English prompts. Just install them normally. And the front audio only has one corresponding fool-proof interface.
7. Indicator light cable interface
HDD LED represents the hard disk light, POWER LED is the power light, RESET SW is the reset button, POWER SW is the switch, PC SPEAKER is the PC speaker, these are The interface can be said to be the most important point, especially the power button. There is usually a mark on the motherboard. Just plug it in according to the instructions on the motherboard.
Step/Method 1
First, connect the power cord from the chassis. There is a relatively wide one. If it is marked USB, then it is on the chassis panel. To connect the cable to the USB socket, find the USB pin on the edge of the motherboard and plug it in.
Step/Method 2
In the wiring harness in the chassis, if you see a line marked HDD_LED, then this is the line for the disk’s work indicator light, and Just connect the corresponding HDD_LED pins on the motherboard.
Step/Method 3
When you see a line marked Power_SW on it, then connect it to PWR_BTN. The position of PWR_BTN on the motherboard can be seen in the previous picture. and HDD_LED are marked in upper and lower rows. Some are marked PWR_SW, but they all refer to the host power switch line; POWER_LED is the indicator light, just connect it to PWR_LED.
Step/Method 4
In addition to these, there is also a more important motherboard wiring in the host, which is the restart switch line. This line is marked RESET_SW on the header.
Step/Method 5
Find the pin marked RESET on the motherboard and plug it in.
The method to plug in the power cord of the computer motherboard is: find the plug with the POWER (PWR) mark on the chassis panel, find the pin with the corresponding mark on the motherboard and insert it. Power cords are wires that carry electrical current. Usually the way of current transmission is point-to-point transmission.
Power cords can be divided into AC power cords and DC power cords according to their uses. Generally, AC power cords are wires that use alternating current with higher voltage. This type of wire requires unified standards to obtain safety certification due to its higher voltage. can be officially produced. DC lines basically pass direct current with lower voltage, so the safety requirements are not as strict as AC lines. However, for safety reasons, countries still require unified safety certification.
1. When connecting the power switch cable to the power switch cable, first find the two-pin plug marked "power sw" on the chassis panel cable, which is white and brown, and then plug it into the motherboard. Just use the pins marked with "pwr sw" or "RWR".
2. The reset switch cable is used to warm-start the computer. When connecting, first find the two-pin plug marked "RESET SW", which is white and blue, and then plug it into the pin marked "Reset sw" or "RSR" on the motherboard. One wire in the middle is empty and two are missing. The two ends are white and green. 3. First find the three-pin plug marked "Power LED" on the power indicator light connection line, and then plug it into the motherboard marked "PWR LED". ” or “P LED” on the pin.
4. First find the two-end plug marked "H.D.D.LED" on the hard disk indicator light connection cable. The connection cable is white and red. Plug it into the motherboard marked "HDD LED" or "IED LED". on the pins. Pay attention to the direction when inserting. Generally, the motherboard will be marked with "HDD LED" and "HDD LED-". Connect the red end to the HDD LED pin and the white end to the pin marked "HDD LED-".
5. First find the four-pin plug of "SPEAKER" for the speaker connection cable. The two wires in the middle are empty. The two ends are red and black. Plug it into the motherboard marked "PEAKER" or "SPK" on the pin. Red plugs into the positive pole, black plugs into the negative pole. Actual power switch: white positive pole, brown - negative pole can be plugged forward or reverse. Reset switch: white and blue, can be plugged forward or reverse. Power switch: The green one is plugged into the P LED pin, and the white one is plugged into the P LED pin. Hard drive indicator light: Green is plugged into "PLED", white is plugged into "HDD LED-" pin. Speaker: Red plugs into the positive pole, black plugs into the negative pole.
Wire as follows:
1: The power supply has a 24-pin main power plug and a CPU auxiliary power plug (4-pin or 8-pin). The motherboard also has a corresponding 24-pin main power socket and a CPU auxiliary power socket (4-pin or 8-pin). Just plug in the power plug accordingly. There is a fool-proof card to prevent you from inserting it incorrectly.
2: This is the situation when the main power supply and CPU auxiliary power supply are plugged in.

Generally, there are 8 motherboard power cords, and every two cords form a group; they are four groups: power switch, restart, power light and hard disk light. Among them, the mainboard power switch line and restart line are not divided into positive and negative ends, and the power supply and hard disk lights are divided into positive and negative ends.
When plugging into the corresponding interface, you only need to know which ones need to be divided into positive and negative terminals, and which ones do not need to be divided into positive and negative terminals. After aligning them with the corresponding pin slots, insert them into the corresponding pins.
