Power Supply Voltage problem!?!?

    I've noticed ever since upgrading to a P4 I've had stability problems,
    especially with neverwinter crashing to desktop during the game... I decided
    to check the power supply voltage output and this is what I found:

    Core 0 1.89V
    Core 1 1.49V
    +3.3 2.59V
    +5.00 4.97V
    +12.00 11.98V
    -12.00 -12.68V
    -5.00 -5.09V

    Now to me the +3.3V seems VERY wrong! .. I've never dealt much with power
    supply voltages so does anyone know if there is something wrong here and
    whether it is motherboard related or powersupply related!?

    Those voltages were read from Motherboard Monitor 5

    Skyhawk 400W Power Supply
    Epox 4PCA3 Motherboard
    P4 3Ghz

    Thanks for any info!!!

    Read what the +3.3v output is at with a DVM *at* the PSU/MB connector.

    I've tried using a voltmeter at the main ATX power connector on the mobo and
    those voltages read correctly! (3.3v reads as 3.3v) ... any ideas now!? ..
    could this be a motherboard problem? .. or is it the monitoring program's

    I'm so confused,

    on epox

    +3.3 = VDimm voltage. For example:

    On Epox 8rda+ whit enermax 460w:

    +3.3= 2.7
    +5= 5.02

    I would strongly recommend getting a name brand power supply that will be of
    higher quality and have better regulated voltage outputs. Antec is an
    excellent brand for PSU's.

    Try configuring the monitoring program for different hardware or
    install a different program. But gross discrepancies are common with
    this kind of software, and if the 3.3V really was 21% low I doubt that
    the computer would even boot.

    Just to throw you a curve, my 3.3 reads at 1.52

    Agreed. best bang for the buck, too. PCP&C and Enermax are terrific, too,
    but you'll pay more. The Antec PSes are every bit as good, IMHO.
