How to distinguish a "REAL" P4 power supply?

A typical P4 power supply should have following features (EX: 300W)

  • With additional 2X2 4P connector
  • Increased +12V output 12.0 Amps= > 15.0 Amps
    The reason why +12V demand is increasing for P4 system, the VR current for P4 processor are getting the voltage support from +12V rail instead of +5V rail.
  • Increased +5Vsb output 1.5 Amps= > 2.0 Amps
    Trends in PC system power management solutions are driving a need for increased +5Vsb current capability for all ATX-family power supplies to support IAPC(Instantly Available PC), STR(Suspend-to-RAM),....functions.
  • Increased +3.3V output 20.0 Amps= > 28.0 Amps
    Trends in motherboard device such as memory and add-on card are use +3.3V instead of +5V, the +3.3V output capability should be enhances for current applications and future requirements.
  • +5V min. load requirement was very critical for stability & compatibility
    (The most important)

    The reason why to keep +5V output capability was for downward compatible with traditional ATX power supply only, last generation ATX & SFX power supply tend to rely on +5V output to draw a lot of current in order to maintain stable regulation, when this +5V current dropped to a certain level as on those from a P4 system, most of the rails may run out of regulation and therefore cause intermittent failure.
