If you use 4 oc’ed 1080ti’s for rendering, then you should be mainly focusing on their power draw. These online calculators take the highest estimation of every part’s consumption (usually the tdp) and add them, but that’s not what happens in real use scenarios. With 4 gpus, I would only use 3 of them for rendering and keep the primary gpu free, in order to keep working during rendering. So, the primary gpu (the one that drives the monitor) could be a mid-high end card, like a 1070 or a 1070Ti at the most (they are OK in viewport performance).
I think that you can get by with a 1500-1600W psu for this particular use, but there is a good 2000W choice in the market right now, if you want to feel completely safe, or plan to use hybrid rendering (cpu+gpu):https://geizhals.de/super-flower-leadex-platinum-schwarz-2000w-atx-2-3-sf-2000f14hp-bk-a1224766.html?hloc=at&hloc=de
As for the gpu, consider building a custom cooling solution for your rendering gpus. I found this particular version of the 1080Ti very interesting and affordable, considering its prebuild cooling water block, the extremely small size and top cooling performance (below 50°C under full load). https://geizhals.de/zotac-geforce-gtx-1080-ti-arcticstorm-mini-zt-p10810h-30p-a1741325.html?hloc=at&hloc=de

I love my machine, minus the video card. I am going to upgrade that soon. The build cost $6,000 US dollars. Main components are in my signature. My case is a Phanteks Entho Primo. Love it. CPUs Dual E5 2600’s. MB ASUS Z10PE D8 WS, 96 gigs of ram, Cool Master air coolers.
