1/2) ATX_12V/ATX (2x2 12V Power Connector and 2x10 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.

3/4) CPU_FAN/SYS_FAN (Fan Headers)
All fan headers on this motherboard are 3-pin. 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.
