CAUTION
Use only an ATX12V-compliant power supply with these boards. ATX12V power supplies have
two power leads that provide required supplemental power for the Intel Pentium
4 processor and
the Intel 850 chipset. Always connect the 20-pin and 4-pin leads of the ATX12V power supply to
the corresponding connectors on the D850MD and D850MV boards. Otherwise, the board and the
processor could be damaged.
Do not use a standard ATX power supply. Doing so could damage the board and the processor.
