    Realistically, how much fluctuation should there be in a power supply? My 12v rail has dropped to around 5v. I am getting random crash's that I can't figure out as they are always different causes. Now I am wondering about the power supply. Ram memtest and RAM is good. I have 2 SATA drives, 2 DVD drives, floppy, creative x-fi sound card and I am using a 480w power supply.

    Any power supply that allows the 12V to drop to 5V under load should be replaced... but a 480 Watt unit should be ok. There are power supply testers available for $15 at Outpost, Frys, CompUSA, etc.
    What are you using to determine this fluctuation?

    My tester

    Do you happen to have an asus mbd ?
    It has Probe to install and check votage.
    If not see if your mbd came with a test utility or a download.
    Best to use theirs.
    The line should stay straight.A slight movement is ok but the voltage
    should be close to default shown.
