Pentium® 4 processor-based PC should use at least a 250 watt ATX12V power supply, and a chassis that mechanically supports the processor heat sink assembly. Pay very close attention to each component you intend to install into your PC.
CAUTION Failure to use an ATX12V power supply or not connecting both additional power supply leads to the Intel® Desktop Board may prevent the system from booting. It may also result in damage to the desktop board and/or power supply.
System designs based on Pentium® 4 processors will require ATX12V power supply. The extra +12V power connector enables the delivery of more current to the Pentium 4 processor. The presence of the +12V 4-pin connector indicates that the power supply is an ATX12V. The absence of the +12V 4-pin connector indicates that the power supply is not compatible.
Avoid using 1x4 to 2x2 Cable Adapters
The new +12VDC connector lies near the processor's DC-to-DC converter and voltage regulators, which affords higher power conversion and transmission efficiencies and future platform flexibility.
