(2x12 Main Power Connector and 2x3/2x4 12V Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all the 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 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.
