    Who needs firecrackers, when popping transistors is way more fun!

    Most of them fared a lot better than expected. Or is it table format that gives that impression?

    Most of them exploded and could only do between 250-350w DC when labeled 450-550w.

    The only one that managed to be decent out of this round-up was the Huntkey made unit as it shut down properly before it exploded.

    Googling "IP S400CQ2-0" found no instock listings (newegg oos IP S450CQ2-0). AMAZON has the IP S350CQ2-0 $40.69 and up shipped. Not at Tiger Direct.


    Best buy does list the Antec VP 450 for $37.98 free shipping.

    Does this mean pretty much any 5 volt heavy psu is bad news? (what I have been assuming).

    5V heavy is just an extremely old design. All of the power hungry components (CPU, GPU) are powered by the 12v rail these days, so that's the rail which should have the most current available.
    No wonder it doesn't work! You installed the coils backwards

    An extremely +5V heavy design is from about 2005 or earlier, sometimes used up to about 2007. After that the PSU shifted very heaviely to +12V, with actual modern Designs with about 15A on +5V and/or +3,3V...

    Xbitlabs did some measurements about power consumption a while ago. Most of the systems used about 5A on +5V, except for the LGA1366...
