How I should deal with 8+6pin power connectors on 1070

Hello!

I am planning to ubild 8x 1070 rig based on KFA2 1070 EXOC: http://www.kfa2.com/kfa2/graphics-card/kfa2-geforcer-gtx-1070-exoc-sniper-black.html

But it have 8+6 pin connector. I am thought about using 2x EVGA (not sure about 750W-1000W yet). But there are very few available with such number of PCI-E power outputs.

What you will recommend? I have 2x EVGA G2 750W already and it's have 4x PCI-e outputs each (not enough).

You won't be running kfa's at full draw so 2 EVGA SuperNOVA 850 G2's would be a good call - always good to leave some headroom.
For the connectors get a AWG PCI-E 8-Pin Male to 2x PCI-E 6+2 Female Splitter if you want to save on PCI-e 'puts.
