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 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.
