With the use of the power connector, the power supply can supply enough stable power to all the com-
ponents on the motherboard. Before connecting the power connector, rst 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 con-
nector mainly supplies power to the APU. 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.
