Thanks guys, great help 
wishing you all a prosperous 2018!
DO NOT BUY THE EVGA 750GQ's!! THEY ARE CRAP!!!! wishing you all a prosperous 2018!Seriously, I've rma'd two of them in the space of 2 months. They are not built to sustain high, constant load. The G2's are a lot better but do yourself a favour and AVOID THE GQ!!!!!
OK good to know, I already have one so will see how I get on with that one, but I won't buy another
Considering 1070Tis for the 6 gpu onda board too, so I'd have to pick a different PSU in that case.
