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 computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high
power consumption be used (500W or greater). If a power supply is used that does not provide the
required power, the result can lead to an unstable or unbootable system.
