GTX 580 on 450W PSU?

Solution
You want a minimum of 42amps on the 2v rail for that card. the 550w version of that model delivers 45A and is literally the same price as the 450w version at the moment. SO that would be my suggestion. Should also run a gtx 670 (which is also a gtx 760- and gtx 760 is cheaper I believe)

PSU make/model look reputable. So my recommendation is go for the 550w model.

Yea I don't have a big budget to upgrade my graphics card, however on eBay I've seen some GTX 580's go for $110.
So the basic answer is no, I would not be able to run a GTX 580 on my current PSU?
So are you saying that a GTX 670 would work on my PSU?
