The FDD-type power connectors are additional power connector.s If
you are using more than one graphics cards, we recommend that
you plug power cables from your power supply unit onto the 5V/
12V power connectors. This will provide more stability to the entire
system. The system board will still work even if the additional power
connector is not connected.
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 instabil-
ity 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 orientation before plugging the connectors.
