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.

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.
