Power and Hardware Connectors
CAUTION
Failure to use an ATX12V power supply, or not connecting the additional power supply lead to the
D845HV or D845WN board may result in damage to the desktop board.
The D845HV and D845WN 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.
Figure 21 shows the power and hardware connectors.
