Intel Desktop Board D925XCV/D925XBC Technical Product Specification

2.8.2.1Power 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.

Alternate power – a 1 x 4 connector. This connector provides additional power when using high wattage PCI Express x16 graphics cards.

INTEGRATOR’S NOTE

When using high wattage PCI Express x16 graphics cards, use one of the following power supply configurations to avoid system instability:

The preferred method of power delivery is to use a power supply with a 2 x 12 main power cable. In this configuration, use two connectors to provide power to the board:

The main power connector

The ATX12V connector

In this configuration, the alternate power connector is not required. The 2 x 12 main power cable can provide up to 144 W of power from the +12 V rail.

An alternate method of power delivery is to use a power supply has a 2 x 10 main power cable. In this configuration, use three connectors to provide power to the board:

The main power connector

The ATX12V connector

The alternate power connector

The combination of the 2 x 10 main power cable and the alternate power cable can provide up to 144 W of power from the +12 V rail (72 W each).
