components on the motherboard. Before connecting the power connector, first make sure the power
supply is turned off and all devices are properly installed. The power connector possesses a foolproof
design. Connect the power supply cable to the power connector in the correct orientation. The 12V
power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the
