2.2.2.3 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 to the main
power connector, leaving pins 11, 12, 23, and 24 unconnected.
• Processor core power – a 2 x 4 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.
