Power Connectors

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 CN3 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.
