Hardware Installation

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 recommend 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 approximate power usage is important to ensure that the
power supply meets the system’s consumption requirements.

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 orien-
tation before plugging the connectors.

The FDD-type power connector is an additional power connector. If you are using
more than one graphics cards, we recommend that you plug a power cable from your
power supply unit to the 5V/12V power connector. This will provide more stability to
the entire system. The system board will still work even if the additional power
connector is not connected.
