2.7.9 Power Connectors
We recommend that you use a power supply that complies with the
ATX12V Power Supply Design Guide Version 1.1. Connect the
ATX12V power supply’s 20-pin ATX main power connector and
4-pin +12V power connector to J17 and ATXP1 respectively.
The 4-pin +12V power connector enables the deliver y of more
+12VDC current to the processor’s Voltage Regulator Module
(VRM).
The mainboard 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.
