2.6.13 Power Connectors
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
and a 4-pin +12V power connector that must be inserted onto
CN2 and CN4 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.
