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, pins 11, 12, 23, and
24 must remain unconnected.
• Processor core 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.
CAUTION
If a high power (75 W or greater) add-in card is installed in the PCI Express x16
connector, that card must also be connected directly to the power supply. Failure to
do so may cause damage to the board and the add-in card.
