When we assemble a computer or replace hardware, the connection of the power cord to the motherboard is a critical step. This article will give you an in-depth explanation of the connection method between the power cord and the motherboard by PHP editor Zimo, covering the corresponding relationship between different types of power cords and motherboard slots. By reading this guide carefully, you will learn how to connect the power cord correctly to ensure your computer starts up smoothly and runs stably.
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
1. Pin 1: Connect to the black wire A of the speaker wire of the radiator fan (power fan);
2. Pin 2: Connect to the speaker of the radiator fan (power fan) The gray line B of the cable;
3, pin 3: connected to SG on the power supply motherboard, indicating the Power Good signal;
4, pin 4: connected to the Grounding on the power supply motherboard ;
5. Pin 5: Connect to the 5V on the power supply motherboard; 6. Pin 6: Connect to the +5V Standby on the power supply motherboard; 7. Pin 7: Connect to the -12V on the power supply motherboard on; 8. Pin 8: Connect to +12V on the power supply motherboard; 9. Pin 9: Connect to +3.3V on the power supply motherboard; 10. Pin 10: Connect to PS_ON on the power supply motherboard; 11. Pin 11: Connect to the Grounding on the power supply motherboard.
Motherboard jumper connection method:
1. POWER SW power switch, which controls the switch of the computer. It is generally a two-pin design, regardless of positive and negative poles; RESET SW restart switch, controls the computer to reset. Start up, regardless of positive and negative poles; HDD LED hard disk work indication, etc., shows the working status of the hard disk, divided into positive and negative poles, the indicator light will not light up if connected reversely; POWER LED power switch indicator light, shows whether the computer is powered on, divided into positive and negative poles , it will not light up if it is connected reversely; the SPEAK speaker has positive and negative poles, usually a four-pin interface, and it will not alarm if it is connected reversely.
2. The distribution of the main parts on the computer motherboard, including the CPU, memory, jumper connection locations, audio, etc.
3. The front USB connection is much simpler, because the chassis connection cable has changed from the original scattered multiple lines to an integrated design, and many motherboard USB pins are modular. The design is fixed in a module, making it easy to find the location.
4. For the connection of the front audio pins, mainstream motherboards nowadays basically use a fool-proof design with one hole left open. Just find the pin and plug it in directly.
Motherboard jumper connection method (power indicator light, power switch, reset jumper connection method)
1. Power switch connection cable
When connecting the power switch connection cable, First find the two-pin plug marked "powersw" on the chassis panel connection, which is white and brown, and then plug it into the pin marked "pwrsw" or "rwr" on the motherboard.
2. Reset switch connection cable
Used to warm start the computer. When connecting, first find the two-pin plug marked "resetsw", which is white and blue, and then plug it into the pin marked "resetsw" or "rsr" on the motherboard.
3. Power indicator light connection cable
First find the three-pin plug marked "powerled". One wire in the middle is empty and the other two are missing. The two ends are white and green, and then Plug it into the pin on the motherboard marked "pwrled" or "pled".
Reminder: When inserting the power switch connection cable and the reset switch connection cable, you don’t need to pay attention to the pros and cons of the plug. You can plug them in any way. However, since the power indicator light side wiring uses light-emitting diodes to display work and rest, the connection is directional. Some motherboards will be marked with the words "pled+" and "pled-". We only need to connect the green end to the pled+ pin and the white wire to the pled- pin.
4. Hard drive indicator light connection cable
First find the two-end plug marked "h.d.d.led". The connection wires are white and red. Plug it into the motherboard marked " hddled" or "iedled" on the pin. Pay attention to the direction when inserting. Generally, the motherboard will be marked with "hddled+" and "hddled-". Connect the red end to the hddled+ pin and the white end to the pin marked "hddled-".
The switch jumper of the computer motherboard is usually located in the BIOS setting area on the motherboard and is used to control the turning on or off of the hardware devices on the motherboard. Here are the steps for plugging and unplugging the motherboard switch jumper:
1. First, turn off the computer and disconnect the power cord and other external devices.
2. Open the computer case and find the BIOS setting area on the motherboard. The location of the BIOS settings area may vary between different brands and models of motherboards, but it is usually located at the top or bottom of the motherboard.
3. Locate the motherboard switch jumper, which is usually a set of small holes or metal pins.
4. Using needle-nose pliers or similar tools, insert the jumper into the corresponding hole or pin on the motherboard. Usually, one end of the jumper is red and the other end is black.
5. After inserting the jumper, press the switch next to the jumper to test whether the jumper works. If the jumper is working properly, you can restart the computer and check whether the hardware device is turned on or off.
It should be noted that you need to be careful when plugging or unplugging the motherboard switch jumper to avoid damaging the motherboard or other hardware devices. If you're not sure how to insert or remove a jumper or are unfamiliar with the operation of your computer hardware, seek professional help.
