you paid nearly $1000USD for a 1080ti? that's pretty high.

as for power use, set a realistic tdp of ~75% and each card should draw <200W, and the entire system ~1150W

NO lol, i paid 740*

"I didn't buy most of this stuff at the prices I listed, that was just PC part picker auto populating the values it could find, not sure if i want to go with kinguin ebay or what. Haven't looked into it yet need to find a good vendor on a site like that"

They were 787 yesterday from pc outlet tho

Like i said the hardware is a hedge, hahahaha

I guess it does indeed make sense to use two 1000W PSU's when I looked at the number of VGA ports. You would either need to use splitters with the 1600W PSU which is undesirable considering the wattage draw and the rating on the cables. I believe you would use a 24 pin splitter that attaches to the motherboard to make sure both PSU's turn on at the same time.

Well I'm only one short, and couldn't I just run the 8/6 combo through one of the ports?

You think that's too much?

I had looked around and people were saying don't run 2 Ti's off the same port, but everything else would be fine with two.

I ran a 7950 off one port for with a 6/8 pin adapter. Obviously these are not the same cards but I hadn't even considered this would be a problem with that many slots.

Hmmmm maybe I will need to add another PSU and more GPUs to make it whole. I should be able to get 8 going on this board on windows

hopefully I can find them...

Those are damn high prices for the 1080Tis, OP should reconsider the store, even in my country those cards are cheapier than this.

About the TDP, is a good move to reduce the wattage, since those cards are 250W (or more => custom cards) each at 100% power.

Def going to reduce wattage, after he said that I looked into it with my own 1080 and recommended settings. Very little gains to push it higher, although now I'm worried about the adapters. . . We shall see.

Everything will be here in a few days

And no I bought the GPUs for 740 USD

Spoke with a rep from EVGA, pretty sure i can get 7 of them on the PSU safely assuming i limit TDP.

5 of the 8x6 pin combo

4 of the 8 pins

I can't use any more adapters. 7 is the limit on the ti's with these models. And you'd have to cut your power pretty low to get it to work
