How many watts do I need for my power supply?

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?

  1. 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?

    Yes, a 750W psu will do, there's this one for just 95$ : http://www.newegg.com/Product/Product.aspx?Item=N82E16817182264

    Made by super flower, it's a high quality psu, see the review here :

    A higher wattage psu won't run it cooler, it's just pointless.

    Ok thanks, Neweggs estimate was like 1050 watts or something ridiculous like that, you saved my 100 bucks probably, thanks

    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.
