rage he said his budget was 1200 with the windows 7 included in the price so my build makes more since IMO but i do like the corsair 650 but that earth watt unit is 750 watt and will do the job just fine.

is it fairly cheap? and would it help my game go a lot more smoothely without crashing? because right now my games go from 3 minutes, to about an hour sometimes if i'm lucky and then crashes. and it's extremely frustrating.

The Corsair unit is in the same price range klepto. The Earthwatts has some high ripple (within ATX spec, but JUST within) and build quality is not up to the same level. The TruePower New 750W can be had for $20 more and is a better overall unit. Antec is simply competing against themselves here, so unless the EA750 is like $80, I don't recommend it.
