Re: PSU recommendations (PLEASE HELP)!!!!
I agree with Vinman, and have to say that 750 watts is overkill.
The system in my signature gets along fine without overloading the PSU at 850 watts, so compare that to get an idea.
600 watts is the top end of your needs at this point. If you intend to do dual video cards and more HDD's in the future, sure, a 750 watt might be ok, just don't buy a $40 "750" and expect miracles. Always buy premium power supplies whenever possible.
That being said, Corsair 600's are a downright steal right now
