To connect the power switch cable to the motherboard, follow these steps:

Find the motherboard manual: First, you should look for the motherboard's user manual. This manual usually provides detailed instructions on how to properly connect the power button and other front panel interfaces.

Locate the power key pin: Find the area labeled "Front Panel" or similar on the motherboard. In this area, a row of pins or pinholes can be found for connecting the front panel components.

Confirm the port type: Check the port type displayed on the power button. In general, if there is a red (+) and black (-) pin, then it is a simple two-wire interface by inserting the red wire into the red (+) pin and the black wire into the black (-) pin.

Connect according to the manual: According to the specific specifications of the motherboard, consult the corresponding information in the user manual and determine the correct connection method. Some motherboards may provide more complex interface types, corresponding to different colors and numbers of wires, please follow the instructions carefully.

Careful handling: During operation, be careful to handle pins that are small and easy to break, damage or misplace leading to wrong functional configuration and short circuit of the motherboard.

Testing: After the connection is complete, reassemble the computer and power it on for testing. Make sure the power button is working properly to start and shut down the system.

By following these steps, you can ensure that the power switch cable is correctly connected to the motherboard.
