Power Supply Requirements for Pentium 4:
System design based on Pentium 4 processors will require a new power supply. A new superset of the original ATX power supply is now defined and called, "ATX12V."
The new +12V power connector enables the delivery of more +12 VDC current to the motherboard. The presents 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 an ATX.
Increased +12VDC output is due primarily to the higher power conversion and transmission efficiencies of +12VDC relative to +5VDC or +3.3VDC. Components on the motherboard having unique voltage requirements are expected to be powered by DC/DC converters of the +12VDC power supply output.
An ATX power supply supports motherboards that rely on DC/DC conversion from +5 VDC and +3.3VDC. However, an ATX12V power supply supports motherboards that rely on DC/DC conversion from +12VDC, +5VDC, or 3.3VDC yielding more application flexibility for future platforms.
ATX12V power supplies should be backward compatibility to existing ATX motherboards. ATX12V power supplies are expected to maintain the +5VDC and +3.3VDC output capability.
IT IS REQUIRED THAT ALL PENTIUM 4 PROCESSOR-BASED PLATFORMS USE POWER SUPPLIES HAVING A +12VDC 4-PIN CONNECTOR FOR INCREASED CURRENT SPECIFICATIONS.
Weight: 3.5lb. We use the net weight of a power supply as a crude and easy measure of the quality. For the same wattage, the heavier, the better. Click here for more details.
