Power Supply for 6 x GTX 1080 Ti

Anyone know a PSU for this?

Very little wattage on other components.

Highest PSU I could find was a 1600W

Why are you even using 6 1080ti in one build? Or is that a typo?

Mining presumably.

580 is slightly better than a 1080 in some but the 1080 ti is king although you could get 2 580's for the price of a 1080 ti

A single 1080ti can peak up to 315 watts (for the card alone) under a high gaming load, as seen here.

315 • 6 = 1,890w from the GPUs alone.
1,890 + 70w which is probably over estimating the consumption of the rest of the parts = 1,960w for total system power consumption.

I suggest a high quality 2000w+ wattage power supply, which only one is listed on PcPP: Super Flower SF-2000F14HP.

What region are you to be purchasing parts from?

Can't view the link but are you sure that is not from the wall and is not total system power usage?

I would just use two 1300W PSU's. Cheaper due not needing to import it and the base price, and would provide more wattage. Although you will definitely want to check if your house can handle drawing like 2200W from the wall.

Yeah:

How do we do it? Simple in theory but surprisingly difficult in practice, we are intercepting the power being sent through the PCI Express bus as well as the ATX power connectors before they go to the graphics card and are directly measuring power draw with a 10 kHz DAQ (data acquisition) device. A huge thanks goes to Allyn for getting the setup up and running. We built a PCI Express bridge that is tapped to measure both 12V and 3.3V power and built some Corsair power cables that measure the 12V coming through those as well.

The GPU OCed in Metro Last Light 4K total power from 8 pin, 6 pin and MB 12v averaged at 290w.

That's probably a better idea. I just wasn't sure that was possible.

Its possible, you just need a case that supports two PSU's although if you are wanting 6 GPU's you won't be using a normal case so that shouldn't be a problem and either to get a device to turn the second PSU one when the first one turns on or do it by hand.

Is there any safe and easy way to use 2 power supplies?

Yup! Check it out: http://www.add2psu.com/ The headline even answers your question almost exactly.

Connect two or more power supplies easily and safely!

gddr5x is bad for bitcoin even my r9 290 is outdoing my gtx 1080 also a gtx 1070 can outpace a 1080 because of the 5x dont know about 1080 tis though
