Power Supply Connectors
The board has three power supply connectors:
•
Main power – a 2 x 12 connector.
This connector is compatible with 2 x 10 connectors
previously used on Intel® Server boards.
The board supports the use of ATX12V or
EPS 12V 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 right most
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.
