Power Supply Connectors

The board has the following power supply connectors:
• Main power – a 2 x 12 connector. This connector is compatible with 2 x 10
connectors previously used on Intel Desktop boards. The board supports the use of
ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables. When
using a power supply with a 2 x 10 main power cable, attach that cable on the
rightmost pins of the main power connector, leaving pins 11, 12, 23, and 24
unconnected.
• ATX12V power – a 2 x 2 connector. This connector provides power directly to the
processor voltage regulator and must always be used. Failure to do so will prevent
the board from booting.
