Is 750w big enough for SLI 680s?

[samotage]

Hey Guys.

I would just like to know how much Wattage I'll need for this setup:

CPU - i7 3930K
RAM - Corsair Vengeance 32 GB (8×4 DIMM) 1600Mhz
GPU - NVIDIA GTX 680 FTW 4gb
MOBO - ASUS Sabertooth X79 Motherboard
HDD - Seagate Barracuda 3 TB
SSD - Samsung 830 256 GB

Will a Corsair HX750 be enough for all this? If I add another 680 what would the requirement then be?

Thanks for your time!

Okay. So would 850w be too much then?

If you want and have the money, you can buy one with 850w, the 750w will do, but if you want to stay 30% of the max load, get the 850w.
This is with the 680 GTX in SLI in mind.

Okay. Thanks! Is the corsair HX850 good or is there something else you would recommend?

There's the SeaSonic X-850, it's the best psu with 850w.
But that one is also a good one, see what's the cheapest.

Here is Guru3D's power supply recommendation:

GeForce GTX 680 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 680 SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina. Source http://www.guru3d.com/articles_pages/geforce_gtx_680_review,9.html Agree with above the SeaSonic X-850, it's the best psu with 850w.
But that one is also a good one, see what's the cheapest.

The corsair HX850 is cheaper than the seasonic but only but $30.

Then get the corsair HX850, not much quality difference though, they're both modular, 850w quality psu with enough amps for two 680 gtx.

id rather get a xfx xxx 750w for 84.99. 670s and 680s dont draw a ton of power, but the 3930k kinda does....
