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 20-pin ATX main power connector, a 4-pin +12V power connector and a 6-pin auxiliary power connector that must be inserted onto PL1, ATXP1 and ATXP2 connectors respectively.
The 4-pin +12V power connector enables the delivery of more +12VDC current to the processor’s Voltage Regulator Module (VRM).
The 6-pin auxiliary power connector provides additional current for the board’s +3.3VDC and +5VDC. Using a power supply that does not have this connector will still provide power as long as the 20-pin ATX main power and 4-pin +12V power are connected.
The system board requires a minimum of 250 Watt power supply to operate. Your system configuration (amount of memory, add-in cards, peripherals, etc.) may exceed the minimum power requirement. To ensure that adequate power is provided, use a 300 Watt (or greater) power supply.
