Installing and Replacing Desktop Board Components

Connecting Power Cables

CAUTION

Failure to use an ATX12V power supply, or not connecting the 12 V (2x2) processor core voltage power supply connector to the desktop board may result in damage to the desktop board and/or power supply.

Connecting 2x10 Power Supply Cables

The 2x12 main power connector on the desktop board is backwards compatible with ATX12V power supplies with 2x10 power connections. Use of the 1x4 power connection is recommended with ATX12V power supplies with 2x10 connections when using PCI Express video cards that can consume up to 75 W. Figure 24 shows the location of the power connectors.
