I need a power supply for my superclocked evga gtx 770 I was thinking of buying a 750 watt PSU.
Is 750 watts overkill?
I was also thinking of getting the last Thermaltake 600 watt PSU at best buy on sale for 45 dollars.
Although most people dislike Best Buy,it seems to be a good deal.
Is 600 watts enough or am I better off going with my 750 watt.
Thanks for the help-Brad

750 Watts is not overkill if your going to SLI, But 650 Watts will be sufficient. Also dont buy a Thermaltake PSU they have a lot of failures in a short period of time.

I actually just bought a Thermaltake 700 watt psu the 12v rail has a output current of:52A so I thought it would be good for my superclocked 770. If the Thermaltake goes bad the warranty will hopefully cover it.But when you say a short period of time m0j0...How long exactly?

I bought a 600W Thermaltake, and it died after 5 months, for some even less. Not saying that all the Thermaltakes PSU are bad, some are pretty good but are costy.

Thermaltake has one of the highest rate for PSU Failures.
