Connecting Power Supply Cables

CAUTION

Failure to use an appropriate power supply and/or not connecting the 12 V (2 x 4 pin) power connector to the Desktop Board may result in damage to the board or the system may not function properly.

The 2 x 12 pin main power connector on the Desktop Board is backwards compatible with ATX12V power supplies with 2 x 10 connectors. Use of the 1 x 4 power connector is required with ATX12V power supplies when using PCI Express add-in cards that can consume up to 75 W. Figure 30 shows the location of the power connectors.
