2.8.19 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, 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.
