How to correctly connect the motherboard power cord has troubled many novice players. PHP editor Xigua brings you a motherboard power cord plugging guide. It introduces in detail the specific plugging methods of various motherboard power cords such as 24PIN, 8PIN, 4PIN, etc., and attaches a clear plugging diagram. This article will help you easily master the motherboard power cord plugging skills and avoid hardware damage caused by improper plugging.
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, look for the USB pins on the edge of the motherboard and plug them 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 boot cable on the motherboard is generally composed of two pins, which need to be plugged into the corresponding pin positions on the motherboard to start the computer normally. The following are the specific steps for plugging in a ribbon cable:
1. Find the pin position marked "POWER SW" or "POWER BUTTON" on the motherboard, usually at the bottom of the motherboard near the edge of the front panel.
2. Insert the two pins of the power-on cable plug into the corresponding pin positions according to the positive and negative poles. Generally speaking, the black plug is the negative pole, and the white or colored plug is the positive pole. You need to pay attention to the direction of the plug when inserting.
3. Plug the power cord of the computer host into the power socket and turn on the power.
4. Press the power button. If the cable is plugged in correctly, the motherboard will start the computer.
It should be noted that the position and shape of the boot cable interface of different brands and models of motherboards may be different. Therefore, when plugging in the cable, you need to read the motherboard manual carefully to determine the correct insertion position. .
Wiring 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.
To connect the computer case power cord to the motherboard, follow these steps:
First, make sure the computer is turned off and unplugged.
Then, find the power socket located near the motherboard and make sure the socket shape matches the connector of the power cord.
Align the power cord's connector with the slot and insert it gently, making sure there is nothing loose.
Next, find the power socket on the motherboard, usually labeled "PWR" or "Power", and connect the other end of the power cord to that socket.
Finally, check that the connection is secure, re-insert the power plug, and turn on the computer. In this way, the power cord of the computer case and the motherboard are successfully connected.
The wiring sequence of the power cord on the main board of the Lijin injection molding machine is as follows: Insert one end of the power cord into the power socket on the main board of the injection molding machine.
Plug the other end of the power cord into an AC outlet.
Turn on the power switch on the main board of the injection molding machine.
Check whether the indicator light on the main board of the injection molding machine is on. If it is on, it means the power connection is successful.
The power cord of the computer motherboard can be plugged in 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 mainboard 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.
