Guys i need someone to answer me this properly or so. IF i were to make 1 rig with 7x 1080 Ti, i plan to buy Zotac AMP! Extreme, how much PSU Wattage i need? Can i do it with 2x 1000? or 2x 860?

I have 1 rig also with Zotac AMP! Extreme, but 1070. Cards are beasts and on 100% they can pull 250W that's their nominal power (although on 100% they never drain more then 150-160W when they do zcash and similiar algos, at least from what i remember). My 7x Zotac 1070 rig draws around 1100 W from the wall (i have watt meter) and they are on 2x Corsair AX860i, so around 1700 W overal. Here i have even 600 wats more then i need. System is super stable and works like a charm. On eth i get 31-32MHS, on signatum around 31 and on Zcash i get 420-430 sols per card.

I run 1 Rig with 7gtx 1070 - 4x Zotac AMP! Extreme, 2x Msi Gaming x and 1x Msi aero on just 2x Corsair HX750i and also works like a charm, i have like 400 watts extra.

And 1 rig runs on just 1 Seasonic 1000w Supply, 6x gtx 1070, those are mix of weaker cards and stronger. 2x Asus dual oc, 1x Zotac mini, 1 Msi gaming x and 2x Gigabyte Aorus. Also runs perfectly fine with no issues. I have like 300 watt extra.

My zotacs are always from 50-60% Power limit, i dont need higher as they give amazing hashrates on this, and they just start heating more, so it's not worth it.

I guess 1 1080TI on 50-70% power limit shouldnt drain more then 225w per card, that equals 1575 + cpu mobo and such. I would say 2x1000W or 1x1000 + 1x860 should be enough or?

Dunno why you put this

The AMP Extreme is inadequately cooled according to GamersNexus.I have 1 rig also with Zotac AMP! Extreme, but 1070.

**huge numbers**and use 1200W PSU-s for just 3 or 4 cards.Hmmm that's odd. I have Gtx 1070 AMP! EXtreme, they look the same like 1080Ti and i like how they cool. Cards are not over 47-55 degrees and on 57 - 64% fan. True, 1080 TI will take more power so probably fans need to work faster if they didnt changed cooling system a bit. Hmmm i'll check it out.

Is cooling system on Gaming X 1070 and 1080Ti the same? If so then Zotac should be better, as my Zotac 1070 cools better then 1070 Gaming x

Edit: ooh seen that vram and fet temps are also important and not so cooled. Hmmm, what do you guys suggest? Which one should i get, cooling is most important to me.
