3) ATX4P (PCIe Power Connector)
The power connector provides auxiliary power to the onboard PCI Express x16 slots. When two or more
graphics cards are installed, we recommend that you connect the SATA power cable from the power supply
to the ATX4P connector to ensure system stability. For 4-way CrossFireX™/SLI, you must connect the
ATX4P connector.

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 conguration jumper blocks. Do not place a jumper cap on the •
headers.
4/5) CPU_FAN/FAN1/FAN2/FAN3/FAN4 (Fan Headers)
All fan headers on this motherboard are 4-pin and support fan speed control function. 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.
