1/2) ATX_12V/ATX (2x2 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, 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 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.
The motherboard has a 4-pin CPU fan header (CPU_FAN), two 3-pin system fan headers (SYS_FAN1
and SYS_FAN2), and a 3-pin power fan header (PWR_FAN). Most fan headers possess a foolproof
insertion design. When connecting a fan cable, be sure to connect it in the correct orientation (the black
connector wire is the ground wire). The motherboard supports CPU fan speed control, which requires
the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended
that a system fan be installed inside the chassis.
