I'm using a GTX260 full-power on a cheapo 500W PSU.Rydian said:The 57x0 states a 450W PSU requirement, and with PSUs the wattage isn't everything, since the PSU listed with his computer wasn't named, we can't be sure it's not a cheap one, in which case we don't want to risk overloading it, so I'd recommend a lower-end card.
Yes, I know. I promised myself I'd get a modular PSU soon.
Instead I never got one and this 500W one is still going strong
