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.

required power, the result can lead to an unstable or unbootable system.
