I bought EVGA's 1080 Ti FTW3 Hybrid yesterday. Their gaming performance is pretty much identical. Asus's GPU temp. maxed out at a respectable 73C http://www.tomshardware.com/reviews/asus-rog-strix-geforce-gtx-1080-ti-oc,5225-5.html. EVGA's GPU max. temp. was 46C https://overclock3d.net/reviews/gpu_displays/evga_gtx_1080_ti_ftw3_hybrid_review/7. For what it's worth EVGA's core clock OC'd to 1976MHz out of the box(1569MHz) and has headroom for OC'ing. At similar price points the EVGA would be my choice.

You don't need a 1200W PSU, you don't even really need a 700W PSU.

If you really want a 1200W PSU, there's only really a couple of options and they're all pretty good.

If you want to have comfortable head-room and be able to overklock and not stress your PSU you can get THIS Thermaltake Toughpower Grand RGB 850W 80+ Gold Smart Zero 256-Color RGB Fan Fully Modular Power Supply 10 YR Warranty , AMAZON https://www.amazon.com/gp/product/B01MQU6CWU/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

The $$ difference in power supplies only about ~$150 between 800w - 1200w units and your budget does not seem to be a problem. So get one that looks good. Corsair and Thermaltake make large supplies that work great. I have a Thermaltake 1050 Gold DPS that I plugged and never think about.

But man, that is a lot memory. Cut it down to 32G and save $500. I have the same memory at 16 G and I rarely go over %40 usage. 32G should be fine.

Forget the WD 3tb and get another SSD with the $500 you save on memory. Once you get your rig up and running a mechanical hard drive is going to seem archaic. But wait a while, because I think ssd prices will improve this spring.

Also - the case is nice but too small for you. Don't suffocate this beautiful machine you are creating.

if you are overclocking you will need a min of a 850W PSU, those i9's are serious power hogs when pushed.

For today standards, that's not a good build at all, that build is using aging parts and a old platform., I have seen multiple videos of people doing dumb things too. Doesn't mean that i'm going to do the same.

A 650w PSU will be more than enough even when overclocking.
On a gaming load, this system would consume ~350w.
Not sure why everyone is suggesting 850w+ units? 850w would be enough for GTX 1080ti SLI.

Agreed. I went with the SeaSonic SSR-650RM 650W PSU. http://www.buildcomputers.net/power-consumption-of-pc-components.html can help to estimate how much power your PC is using. You need to remember that what your system is using and the power draw from the wall are going to be different. The power draw at the outlet will always be higher than what the system is using. That's where that 80+ bronze, silver, gold, platinum or Titanium rating comes into play. For those of us who pay an electric bill it does make a difference. Quality units also have protections in place so that if there is a castrophic failure the PSU won't take out the rest of the components with it. .
