Do you think i would be able to get anything a bit cheaper than that?
What's your budget for the PSU? Tot sys Power consumption witha GTX660 is 292w.
If you OC or add after market cooling than it'll increase.
BUt, either the Antec & Corsair cx suggested will work. I would only add,
stay with quality brands such as the two already mentioned.
Personally, I would try to always go a step up from the opening price point/budget
series regardless of brand, Generally you get better value (not cheaper) as
the components are better.
