What psu to get to run ASUS STRIX GeForce GTX 1080 8GB GAMING OC?

What psu to get to run "ASUS STRIX GeForce GTX 1080 8GB GAMING OC"? Will Corsair HX1000i work? Will these parts fit together as i guessed?

I was thinking on building a PC with these parts.

GPU: ASUS STRIX GeForce GTX 1080 8GB GAMING OC
Motherboard: ASUS STRIX X99 GAMING ROG
RAM: Corsair Dominator Platinum 32GB (2x16GB) 3200MHz / DDR4 / CL16
CPU: Intel Core i7-6850K 12 Trådar / 3.6Ghz (3.8Ghz Turbo) 15MB / Socket 2011-3
PSU: Corsair HX1000i 1000W
Storage: MemorOCZ RD400 512GB M.2
Chassi: NZXT S340
CPU cooler: NZXT Kraken X61 280mm

Sounds like a working beast, right?

I would suggest not getting a 1000W PSU for the GTX 1080. Perhaps 550-650W would be enough. PSUs tend to have a bell curve efficiency with 50% load being its peak. 1000W seems to be rather overkill for a single GPU system. To get started, I would refer you to EVGA's Supernova G2 550W at Newegg for $75.

Also 32GB is too much if you're gaming only. 8 or 12 GB would do the trick though I would go for 16 GB.

hmmm, i want to be able to uppgrade with another card in the not so far future that why i took such a big W, maybe i should go for 850W for room to expand?

ASUS indicated that the GTX 1080 Strix consumes 300W (Overclock3D reports 336W at load). If you are going to have two 1080's in 2-Way SLI then your system might consume somewhere around 800-850W with an overclocked CPU. Your 1000W PSU would then be ideal in this situation.

PS: Although, I cannot fathom needing two 1080s for gaming unless you want to play in 4K @ 60 fps or VR. Are you gaming in 1080p, 4K, or is this for VR?
PPS: My math for the PSU might be wrong somewhere, its a bit late at night here.

Yes, i am thinking about gaming in 4k 60fps now and then with the extra card to get to 120fps in 4k and such when i uppgrade my screen. maybe even try some VR, to keep testing the limits kinda.

Ah, I see, that makes sense. 1000W would be ideal then for this situation.
