Psu calculators for the most part are highly inaccurate. The one you use is an example of that. 

A decent 750w is recommended and even a solid 650w would be enough.

You can be fine with a good 850W or a 750W PSU. Some brands I recommend are Seasonic, Corsair, XFX, some EVGAs, and Silverstone.

I like the color scheme of Noctua fans. Deal with it. Forget about the bad memories of the past.

Forget about the bad memories of the past, take the good ones along with you through the present, and look forwards to the good things that will come in the future.

I would get an 850W to minimize load on the PSU and perhaps reduce PSU fan noise.

Get a really solid 6-750. As wooden said, the calculators are usually bullshit.

Beneath this mask there is more than flesh. Beneath this mask there is an idea, Mr. Creedy, and ideas are bulletproof.

As I get older I get angrier more cynical, meaner. I feel some warning posts coming. I feel a ban coming. I was warned.

Because a sli of 770's performs 15%-40% better than a titan and around 10% better than a 780ti.

If it has to be fully modular, well there isn't any competition against the 750 G2.
