F_PANEL(NH) PWM Switch (X58A-OC) BIOS Switcher (X58A-OC) 1 M_SATA 3) ATX4P1/ATX4P4 (PCIe Power Connectors) The power connectors 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(s) from the power supply to the ATX4P1/ATX4P4 connector toDIP ensure system stability. For 4-way CrossFireX™/SLI, you 1 23 must connect at least one of the ATX4P1 and ATX4P4 connectors. 1 DIP 1 23 PCIe power connector (SATA)(X58A-OC) DIP 1 23 1 DIP 1 23 1 Voltage measurement module(X58A-OC) DB_PORT Pin No. Definition 1 NC 2 NC 1 3 NC 4 GND 5 GND 6 GND 15 7 VCC 8 VCC 9 VCC 10 GND 11 GND 12 GND 13 +12V 14 +12V 15 +12V F_AUDIO(H) F_USB30 TPM w/housing 4/5) CPU_FAN/FAN1/FAN2/FAN3/FAN4/FAN5/FAN6 (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. 1 CPU_FAN 1 FAN1/FAN2/FAN5/FAN6 1 FAN3/FAN4 CPU_FAN: Pin No. Definition 1 GND 2 +12V/Speed Control 3 Sense 4 Speed Control FAN1/FAN2/FAN3/FAN4/FAN5/FAN6: Pin No. Definition 1 GND 2 +12V /Speed Control 3 Sense 4 Reserve •• 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 configuration jumper blocks. Do not place a jumper cap on the headers. Hardware Installation - 26 -
