Use a power supply that complies with the ATX12V Power Supply Design Guide
Version 1.1. An ATX12V power supply unit has a standard 24-pin ATX main
powerconnectorthatmustbeinsertedintothe24-pinconnector.The4-pin+12V
powerconnector enablesthedeliveryofmore+12VDCcurrentto the processor’s
VoltageRegulatorModule(VRM).
The power connectors from the power supply unit are designed to t the 24-pin
and4-pin connectors in onlyoneorientation.Makesure tondtheproperorien-
tationbeforepluggingtheconnectors.
The system board requires a minimum of 300 Watt power supply to operate.
Your system conguration (CPU power, amount of memory, add-in cards, pe-
ripherals, 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.
Important:
Insufcient power supplied to the system may result in instability or
the add-in boards and peripherals not functioning properly. Calculating
the system’s approximate power usage is important to ensure that the
powersupplymeetsthesystem’sconsumptionrequirements.
