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.

1Hyper-Threading Technology requires a computer system with an Intel® Pentium® 4 processor supporting HT Technology and a Hyper-Threading Technology enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. See http://www.intel.com/info/hyperthreading/ for more information including details on which processors support HT Technology.
