I plan to buy a MSI GTX 1080 X 8GB Gaming sometime soon, but would like to know how powerful a PSU to upgrade to to handle it. My build link will be below.

Note: The GPU on the list is the founder's edition as it is the only version on the market as of now. Also most of the parts are already in the pc and I can't replace them right away so the PSU and the GPU are the only things getting changed

Currently I am looking at this PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438018 as the brand is well recommended and the unit is gold certified. I do plan on overclocking the CPU and GPU to some degree, though not to the maximum possible due to fear of heat damage as I live in a hot and dry climate.

Thank you in advance,
Brendon

Edit: incorrect link, very sorry!

850W is overkill for single GPU + CPU.
You can do it with 600-650W for both, having a good PSU will feed em without any problems, with enough headroom left.
If you plan on sli, yes this 850W will be enough and will give you enough headroom.

600 watts is bare minimum for gaming setups and should only be used if you don't plan on overclocking. 750-900 is the sweet spot for PSU's on single card gaming setups.

I already peak @ 620 watts with an R9 380 and AMD FX 8320. I use an HX 750i
