We recommend that you use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1. An ATX12V power supply has a standard 24-pin ATX main power connector and a 4-pin +12V power connector that must be inserted onto CN8 and CN9 connectors respectively.

The 4-pin +12V power connector enables the delivery of more +12VDC current to the processor’s Voltage Regulator Module (VRM).

The system board requires a minimum of 300 Watt power supply to operate. Your system configuration (CPU power, amount of memory, add-in cards, peripherals, etc.) may exceed the minimum power requirement. To ensure that adequate power is provided, we strongly recommend that you use a minimum of 400 Watt (or greater) power supply.
