Technical Reference 2.7.2.1 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 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. Table 22.

2.7.2.1
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 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.
