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 processors Voltage Regulator Module (VRM).
The 6-pin auxiliary power connector provides additional current for the
boards +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.
