1/2) ATX_12V_2X/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, 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.
• Use of a power supply providing a 2x4 12V power connector is recommended by the
CPU manufacturer when using an Intel Extreme Edition CPU (130W).
• 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 power connectors are compatible with power supplies with 2x2 12V and 2x10 power
connectors. When using a power supply providing a 2x4 12V and a 2x12 power connector,
remove the protective covers from the 12V power connector and the main power connector on
the motherboard. Do not insert the power supply cable s into pins under the protective covers
when using a power supply providing a 2x2 12V and a 2x10 power connector.

3/4/5) CPU_FAN/SYS_F AN1/SYS_F AN2/PWR_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 3-pin (SYS_FAN1) and a 4-pin
(SYS_FAN2) system fan headers, 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.
