I just used Antecs psu calculator because I was told it had accurate calculations. I was not able to fill in many of the areas because I did not know what 80% of what it was asking for was. That said I filled in what I could and it said I could crossfire Radeon 5870 or SLI GTX 460 1gb without going over my 650w psu. Any other card that could be SLI or Crossfire was too much for my psu. So because I was not able to fill in a lot of the other information, would I be able to SLI or Crossfire those cards? I'm pretty sure I would be able to because with the Radeon 5870, the minimum psu wattage was 582. The GTX 460 was even less.
