Can someone already running dual 1080Ti for folding give me some power usage numbers. I'm getting odd results from various power config websites and could use some real world results.

Wait so no-one waited for the Titan Xp?    (Didn't mean to hijack post, thought I was on a different post)    my bad! 

well... i hate to say this but i just couldn't hold onto $1500 without spending it >. < so i'll have two 1080ti's that i can put on my kill a watt power meter and give you exact power draw friday. BUT, i will say that if you are using founders cards they will most definitely be throttling down due to their hard thermal limit of 84C. so unless you are putting them under water you will most likely never see more than ~200W max out of each card.

900 watts with Nibbler - 3GPU - no CPU folding
 
CPU will push it to 1100 watts total system including monitor

I'm looking towards a 1080Ti FTW3 and whatever AIB style card I can stepup my 1080 FTW2 to.
Pretty sure my 660W power supply ain't gonna cut it, but I've seen one SLI review put combined draw at 654 Watts at the wall. I've seen between 1000 and 1350 watts depending on the power supply calculator.

I do not think a single Game out their can push a Graphics Card as hard as Folding and some BOINC GPU Tasks can.

I would say anyone going SLI or Two GTX 1080Ti Graphics Cards should get no less than a 1000 Watt Power Supply.

I don't go to extreme with the overclocking. My CPU isn't overclock able but I do oc my folding cards if possible.

I am running two GTX980Ti and an E5-1550 on an EVGA 850G and it seems to be running fine.
Just make sure your using the heaver duty cord that comes with the 850W and not a light weight one from a 650W PSU.
I learned the hard way!!

I have a server grade power cable from a blade rack. It's a pretty thick cable. I think I'm gonna get a 1200P2 unit for some spare capacity.

The Cable that comes with 1200 P2 is the same size as my Dell Server Cables just not a long.

Anyone think I'm pushing it if I run 1080Ti and 780Ti together on AX850?
1070FTW & 780Ti ran fine though while I had it.

With No GPU Overclocking I would say yes and with GPU Overclocking I would say Maybe you will be OK.

1 - Windows 10 requires November 2015 update or newer.
2 - 7680x4320 at 60 Hz RGB 8-bit with dual DisplayPort connectors or 7680x4320 at 60 Hz YUV420 8-bit with one DisplayPort 1.3 connector.
3 - DisplayPort 1.2 Certified, DisplayPort 1.3/1.4 Ready.
4 - Recommendation is made based on PC configured with an Intel Core i7 3.2 GHz processor. Pre-built system may require less power depending on system configuration.

I am Pushing 850 Watts Folding on my 2 Cards, SLI is Disabled.
Max or Peek Wattage while Folding and or Crunching was 910 Watts.

What cpu are you using?

OK! two 1080ti's on a 650W PSU will work until the ambient room temps start to cool down and the cards are no longer throttling themselves down to 1700MHz. as for what i read from my kill a watt meter i saw 550W avg while it was running and not rebooting itself due to power spikes. 750W should be fine on air, no OC, but 850W is what i would consider safe for two 1080ti's.

the user doesnt set the Mhz the thermal limit does and i did say founders and on air.

1000 platinum is on sale in the EVGA store- 189.99 + shipping

I'm torn right now between that one and the 1200P2. I really need that platinum efficiency. At these wattage, even titanium could save some long term money.
