I don't have the stock numbers but my 1070's did 150-155W overclocked and I belive my 1080ti did 160W oc
Note that these numbers are on solo eth mining
That makes a total of about 850W for all 6 cards at max, your biggest issue will be the power connectors.
I think I have the same psu on the way It has 8x8 6+2 pin connectors, you will need 3 for the 1070s and 6 for the 1080s i believe

Also remember to not connect more than two risers to one sata cable, if you can don't use them at all. Three 1070s will get hot, two rx 570 will burn down your house

Whopsi i made a bummer to
