Intel Desktop Boards D845PT and D845BG Product Guide Power and Hardware Connectors CAUTION Failure to use an ATX12V power supply, or not connecting the additional power supply lead to the D845PT or D845BG board may result in damage to the desktop board. The D845PT and D845BG boards require an ATX12V compliant power supply to function according to desktop board specifications. Both boards have two ATX12V compliant power supply connectors that are needed to provide extra power to the Intel 845 chipset and Pentium 4 processor.
