  1. Yes. A 512 MB GTS250 needs less than 7 amps.

    But your PSU sounds like an older generic unit. You might want to give some thought to upgrading it. I'd suggest a Corsair 400CX (30 amp 12 volt rail):

  2. 22Amps on a 450W PSU means its a low quality PSU.
    A good 450W PSU should deliver 30-33 Amps.

    Don't take any chances.

    Get a new PSU.

    Some options:
    Corsair 400CX:

    OCZ ModXstream 500W:

    Actually it's quite good as most generic PSU's are only pushing 15 -17amps on the 12volt rail.
  4. Efficiency around 58%(Theoretical :) ).
    That shows it is a low quality PSU.
    I know it can handle that card but straining a low quality PSU for long might be harmful...
  5. And may I ask how you got to that number.
  6. Here have a look at this, a 450w PSU with less than 30amp on the 12v but 80% efficient.
  7. P=VI
    On 12V Rail
    P=12X22
    =264W

    Rated 450W

    efficiency=(Output/Input)/100
    =58%

    Don't get mad on me if I'm wrong somewhere :)

    If you click on the link in my post above you will see that it's not quite as simple as that.
  9. i had the same problem when i bought my gts 250. i ended up buying a cooler master GX650W which gives 52A. A bit of an overkill alright but no chances taken whatsoever. it might just come in handy if u add another gts 250. the card's a beauty, especially in SLI, so the benchmarks say.
