1/2) ATX_12V_2X4/ATX (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, 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.
3/4) CPU_FAN/SYS_FAN (Fan Headers)
All fan headers on this motherboard are 4-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 speed control function requires the use of a fan with fan speed control design. For
optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.
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.

• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating. Overheating
may result in damage to the CPU or the system may hang.
• These fan headers are not conguration jumper blocks. Do not place a jumper cap on the headers.
