750 watt pwr supply enough for GTX 295?

I'm building a new sandy bridge system in April. A friend of mine gave me his GTX 295 when he upgraded to the GTX 580. Would a 750 watt pwr supply be enough to pwr my system and the GTX 295?

Here are the specs:

Lian-li 7fnw case
i5 2500k 3.3ghz
Asus p67 pro
Mushkin 8gigs 1600mhz
Samsung F3 7200RPM 1TB
GTX 295
Corsair 750 Watt pwr supply
Prolimatech Megahalems heatsink
Gelid wing 3 140mm Fans 1200rpm...1 intake 2 exhaust
Gelid wing 3 120mm fans 1500rpm...1 exhaust 2 for push pull on Prolimatech Megahalems

Possibly be upgrading to 2 GTX 570's later this summer. Will be overclocking the cpu to 4.0 to 4.5ghz

    Yeah i've been reading up on power supplies and didn't realize how important it was to get a good brand. Most noobs like myself would buy a cheap 750-850 watt pwr supply just because it's $30-50 cheaper.

    even if i overclock my cpu it'll be enough to run 2 GTX 570's in SLI with that pwr supply?
  6. Yeah you do not want to go "cheap" on a power supply. They can die and take other components with them. Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Antec and Enermax for top quality. A few others make good units too but a 750 watt unit for $19.99 is a bad idea. lol

    Yep that was in the " a few others" I forgot at the moment list lol.
  15. Also keep in mind some of the better brands have cheaper models so look for one that's at least bronze rated.

    You know im glad i started looking at reviews of power supply and how to choose the right one because i was really close to getting a cheap 750 watt pwr supply lol...Especally in a new system that's a no no...Alot of people tend to worry about what cpu and gpu they are going to buy but they forget to think about getting a good quality pwr supply.
  17. Nice
  18. Yeah the power supply usually comes after everything else and then there is a bit of money left and they buy the cheapest power supply and then they wonder what went wrong when it blows up
