2.7.2.1 Power Supply Connectors
The board has 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.
• 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.

INTEGRATOR’S NOTE
When using high wattage PCI Express x16 graphics cards, use a power supply with a 2 x 12 main
power cable. The 2 x 12 main power cable can provide up to 144 W of power from the +12 V rail.
