1/2/3) ATX1/P12V_AUX1/P12V_AUX2
(2x4 12V Power Connector and 2x12 Main 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.
