Failure to use an ATX12V power supply, or not connecting the additional power supply lead to the
Desktop Board D850EMD2 or D850EMV2 may result in damage to the desktop board and/or

compliant power supply connectors that are needed to provide extra power to the Intel 850E
chipset and Pentium 4 processor.
Items B and E in Figure 18 on page 60 and items C and F in Figure 19 on page 61 show the two
power connector locations.
