I5 3570k - 2 GTX 660 SC SLI - PSU help needed

[angelpunk18]

Hello, I've been dealing with a faulty PSU that for the reason of the place where I live in (Venezuela) I can't return. that being said I'm a little confused about the PSU I should get

My Specs:
-Intel Core i5 3570k 3.4 ghz
-16 GB Kingston Hyper Blu RAM
-ASUS RoG Maximus V GENE MB
-2 EVGA GTX 660 SC SLI
-Two HDDs: a 3.5 7200RPM 3TB Seagate Barracuda and a Laptop 7200 rpm 160 GB

So, i've been using a couple different PSU calculators online and I've been getting mixed results, some say 600w is enough, some say 700w is my minimum and another one says that i need at least 800w.

Someone told me that a Cooler Master 750 w 80 plus would work just fine, what do you think?

Thank you for your reponses

600w might be enough but I would get 700+w for the peace of mind especially if you are thinking about overclocking.

cooler master is not my first choice of brand for psu. personally i would get antec xfx corsair seasonic pcpower&cooling
