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 Volt-
age Regulator Module (VRM).
The power connectors from the power supply unit are designed to
fi
t the 24-pin
and 8-pin connectors in only one orientation. Make sure to
fi
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
fi
guration (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 recommend that you use a minimum of 400 Watt
(or greater) power supply.
Important:
Insuf
fi
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.
