  1. what else is in the computer? cpu? how many hdds? IMO the 10 amps on the 12v rail is not enough for much at all, a low power cpu, motherboard and 1 hard drive. get another psu.

    I have one WD Gren sata 7200 RPM 1TB HDD, AMD Phenom X4 9550 2.2 Ghz processor and 1 DVD RW drive and 1 MSI K9N2GM motherboard.i guess it is a basic motherboard...nothing else.
  3. That doesn't even come close to adding up to 500w And that 12V could barely run a CPU. Are you sure your reading it right? And there aren't multiple 12V rails. Maybe a pic would help...

  5. Looks like it could be an (old) ATX 1.x PSU. Also, they're lying bastards. 500W? Not even close. You'll need a new PSU.

    Yea... No matter how creative I get I can't get above about 260W. Ballsy even for a PSU maker. If that Web address is navtech.org it goes to a mobile phone maker lol.

    Even if you don't upgrade the GPU I would STRONGLY recommend replacing the PSU ASAP
  7. Buy new psu .it will not work.you need psu with atleast 18a on +12v rail
  8. thanks guys....i'll surely change the PSU soon.
