3) ATX4P (PCIe Power Connector)
The power connector provide 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
1
to the ATX4P connector to ensure system stability.
4/5) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3/SYS_FAN4/SYS_FAN5 (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), five 4-pin (SYS_FAN1~SYS_FAN5) system fan
headers. 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.
• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheat-
ing. Overheating may result in damage to the CPU or the system may hang.
• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers.
