Essential knowledge for computer assembly, how to connect motherboard jumpers?

For computer novices, assembling a computer is a task that requires mastering key knowledge. Among them, the motherboard jumper connection rule is essential. In order to help all computer novices successfully solve the problems encountered during the assembly process, PHP editor Xigua specially brings you this detailed tutorial on how to connect motherboard jumpers. In this article, the editor will explain the functions and connection methods of various jumpers in a simple and easy-to-understand manner, with clear picture examples to guide you step by step to complete the motherboard jumper connection, laying a solid foundation for computer assembly.

1. USB3.0 connection method: First find the USB3.0 motherboard interface. There is a USB3.0 mark near the interface, and it has a fool-proof design, otherwise it will not be plugged in. of.

2. The front USB connection method is then connected to the front USB interface. The motherboard also has USB1 and USB2, etc. It also has a fool-proof design, so it cannot be inserted if it is wrong. 3. Audio (HD AUDIO) connection and then connect the front audio (HD AUDIO) interface. Find the corresponding AUDIO logo on the motherboard. If not connected, the front audio cannot be used.

4. The following is the layout diagram of the switch, power supply, and hard disk indicator light interface. Since there are positive and negative pole connections, the white wire is the negative pole and the colored wire is the positive pole. Therefore, do not plug it in reversely. The consequences will be Unthinkable.

5. Hard disk indicator light (HDD LED) connection method

6. Power on/off button (POWER SW) connection method

7. Power supply LED light (POWER LED) Connection method

8. Reset button (RESET SW) connection method

Motherboard jumper

The connecting wire pins on the chassis panel are generally There is a group at the lower left end of the motherboard near the edge. It is usually a double row of pins. There are about 10 groups in total. They mainly include power switch, reset switch, power indicator light, hard disk indicator light, speaker and other pins.

Type

1. Power switch cable

When connecting the power switch cable, first find the two-pin plug marked "power sw" from the chassis panel cable , respectively in two colors: white and brown, and then plug into the pins marked "pwr sw" or "PWR" on the motherboard.

2. The reset switch connection 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 "RST" on the motherboard.

3. Power indicator light connection cable

First find the three-pin plug marked "Power LED". One wire in the middle is empty and the other two are missing. The two ends are white and green. Then plug it into the pin marked "PWR LED" or "P LED" on the motherboard.

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 "P LED" and "P LED-". We only need to connect the green end to the P LED pin and the white wire to the P LED- 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 " on the pins labeled "HDD LED" or "IED LED". 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. Speaker cable

First find the four-pin plug of "SPEAKER". The two wires in the middle are empty. The two ends are red and black. Plug it into the motherboard marked On the pins with the words "SPEAKER" or "SPK". Red plugs into the positive pole, black plugs into the negative pole. But it turns out that these two wires are not divided into positive and negative poles.
