Any recommendation on PSU for 6x 1080 ti?
at least 2 x Modular Gold or Platinum 850W from eVGA, Corsair, Seasonic, Thermaltake, Rosewill + add2psu wire typeI'd go with at LEAST a 1000 or perhaps an 1100 (3 cards + MB + HD + etc) and at least an 850 but preferably another 1000 (other 3 cards) - TDP on the 1080ti starts at 250, and I suspect there is SOMEONE out there that has even higher from the factory.
Keep in mind that TDP is a TARGET, the card can AND WILL exceed it momentarily at times when the load level shifts.
I'd EXPECT occasional issues from running JUST 3 cards on an 850, that's VERY little room for spike handling, unless they are going to be significantly reduced TDP all the time.
An 850 is NOT going to be enough to run 3 cards AND the CPU/RAM/Motherboard/HD unless the GPUs are VERY MUCH REDUCED on TDP, and it's going to be iffy even THEN.
A 2400 watt server PSU would be plenty, presuming it has all the ATX connections you need to run the MB with AND enough PCI-E and "riser power" connectors - AND presuming you have 220 volts to run it on.
I have 220v setup
whats your opinion on gold vs plat -- my electric bill is the bane of my existence lol
I've found the cards run well @ 200 watts on nvOC -- but if you think there's a better efficiency sweet spot i'm all ears!

Also this PSU example only has 6 pins, but I need 8 pins ?
Is there a setting to disable that in the GPU?
pretty cool mobo adapter if you guys havent seen this already

+ I'm swamped and have been swamped with DIY projects I'm looking to just buy a solid gpu frame or case lol xD they seem relatively similar on ebay . . + around 150 which seems a bit high for what you get . . imo
I'd recommend those platinum server PSUs
This one comes with 6+2 pins at the card end of the cables http://www.parallelminer.com/product/2400-watt-power-supply-kit-for-gpu-mining-94-efficiency-200-240v-up-to-24-gpu
After testing on one rig I'm ordering another 4. Here's my two cents:
Pros:
Good value compared to decent 1000W+ ATX PSUs (in my region at least)
Lots of power overhead
Which also means you should be operating in the efficiency sweet spot
Run risers from a PCIE cable and drop the SATA-PCIE adapters
Compact size and the breakout board keeps the cabling tidy
Cons:
The small stacked fans are VERY loud if it gets hot. My rigs draw ~1100W and at 20˚C ambient it doesn't get loud at all.
Shorter warranty. But I trust server quality gear and will order a spare to have on hand.
If I was being picky:
The ATX replacement module has a screw on barrel plug on the PCIE cable which is a bit fiddly. Probably best to solder it together permanently.
The only C19 power cable I could easily source was more expensive than a regular kettle cord and had a 15A plug so I needed to change that to fit a domestic 10A socket. Both no big deal but a little more work if you were setting up lots of rigs.
Now here's my next question... if you were setting up a max 1080 ti rig (6,8,12,13)
Each ti will get 200 watts.. is there a PSU thatll work for me here? Otherwise dual PSU's of choice?
this psu

and flminer has cables and a pico to add to it.

I believe combining these 2 would allow for a true beast.
I like the 8 pin cables build by filmier
Like the pico he made.
I like the 2400 watt psu from parallel miner.
I have all this gear .
I am not to keen on huge 1080 ti rigs but if that is your choice I would combine the gear above and have at it.
