ATX
1/2) ATX_12V/ATX (2x4 12V Power Connector and 2x12 Main Power Connector)
With the use o the power connector, the power supply can supply enough stable power to all the components
on the motherboard. Beore connecting the power connector, rst make sure the power supply is turned
o and all devices are properly installed. The power connector possesses a oolproo design. Connect the
power supply cable to the power connector in the correct orientation.
The 12V power connector mainly supplies power to the CPU. I 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). I a power supply is used that does not provide the
required power, the result can lead to an unstable or unbootable system.

3/4) CPU_FAN/SYS_FAN1/2 (Fan Headers)
All an headers on this motherboard are 4-pin. Most an headers possess a oolproo insertion design.
When connecting a an cable, be sure to connect it in the correct orientation (the black connector wire is
the ground wire). The speed control unction requires the use o a an with an speed control design. For
optimum heat dissipation, it is recommended that a system an be installed inside the chassis.
• Be sure to connec t an cables to the an headers to preven t yo ur CPU and system ro m
overheating. Overheating may result in damage to the CPU or the system may hang.
• These an headers are not conguration jumper blocks. Do not place a jumper cap on the headers.
