Too much? Too little? Just Right?

  1. It's more than enough. However if I were you i would go with a more well known brand Corsair, Antec, OCZ. A 600-700 watt PSU should be more than enough
  2. Thanks, Appreciate that!
  3. I'd go with this one. It has the same specs as the one you posted, and is made by ABS. http://www.newegg.com/Product/Product.aspx?Item=N82E16817814015
  4. The HD4870x2 uses 264w of power at load, with the rest of your system a 650w would probably run it, but with overclocking, possible RAID, case fans, RAM etc. you're better off going with a quality 750w to keep it in the efficient part of it's power band. The Corsair 750w and PC Power and Cooling 750 are both $100 after rebates and with free shipping at Newegg right now and both get great reviews across the board, go with one of them.
