Power Connectors

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 8-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 fit the 24-pin and 8-pin
connectors in only one orientation. Make sure to find the proper orientation before plugging
the connectors.
The system board requires a minimum of 300 Watt power supply to operate. Your system
configuration (CPU power, amount of memory, add-in cards, peripherals, etc.) may exceed the
minimum power requirement. To ensure that adequate power is provided, we strongly recom-
mend that you use a minimum of 400 Watt (or greater) power supply.
Important:
Insufficient power supplied to the system may result in instability or the add-in
boards and peripherals not functioning properly. Calculating the system's approxi-
mate power usage is important to ensure that the power supply meets the sys-
tem's consumption requirements.
