2.6.8 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
20-pin ATX main power connector and a 4-pin +12V power
connector that must be inserted onto CN9 and CN8 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 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.
