Intel Desktop Boards D845EPT2 and D845EBG2 Product Guide

Power and Hardware Connectors

CAUTION

Failure to use an ATX12V power supply, or not connecting the additional power supply lead to the D845EPT2 or D845EBG2 board may result in damage to the Intel desktop board.

The Desktop Boards D845EPT2 and D845EBG2 require an ATX12V compliant power supply to function according to Desktop Board specifications. Both Intel desktop boards have two ATX12V compliant power supply connectors that are needed to provide extra power to the Intel 845E chipset and Pentium 4 processor.

Figure 15 shows the power and hardware connectors.
