    All good power supplies, but how does your ranking system work ?

    yes that definitely helps thank you, but is there anyway I can get away with something a bit cheaper like around $60 range? I'm only gonna use that 1 video card and not gonna upgrade for a long time. I want something that will run my system good and my video card but not take a whole lot out of my wallet.

    Thanks,

    You do not need a 600W PSU for that card. Based on my assumptions about fans and other minor details, the PSU calculator at http://www.extreme.outervision.com/PSUEngine suggests that 330W would be sufficient. For future expansion, I would suggest that 500W-550W would be enough, but if you aren't planning to expand this one again (after all, it IS an old CPU and socket), you would be perfectly satisfied by a 380W Antec Earthwatts for just $45.
  5. Right. A GTS450 needs, at most, about 9 amps. A good 400 - 450 watt PSU would leave you with a comfortable reserve.
  6. I would suggest this psu its 65 dollars 45 after MIR http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016
  7. Thanks for the help everybody, going to frys now to buy my PSU now :)

    I read some reviews, look what protection each offers, warranty (customer service), the efficiency and the overall quality of it.
