My future computer setup is going to basically be this:
SSD
2x HDD (possibly 4)
2x 7970 ghz edition GPU
4x 8gb 1600 RAM
i7-3770k 3.5ghz quad core CPU
Mid-High end motherboard
2x DVD Burners
Blu-Ray Burner
USB 3.0 Card reader
LED fans

Esitimates told me I needed about 1000w, is that correct? If so are these good power supplies? which would be better?
Corsair or Cooler Master?

A good and reliable 750W will run the entire system easily.

Would getting one slightly more than 750w help it run cooler? Or would it just be pointless?

Hi - realhardtech suggests 800w to CF 2 7970's and there's headroom built in
to that, so amuffin & dj are correct that a 750 will run it. With the amount of
storage devices and multiple burners, you might want to look at good quality 850w units,
but more $$ and that capstone 750 is an excellent psu.
