Guys, I just got my 6 Vega 56 cards... I wanted to power them with an EVGA 1600 G2 but I just don't have enough VGA power connectors! Do I really have to connect 2x 8-pin per GPU? Is that needed for mining?
had the same problem using 8 VEGA 64's, eneded up using 2 EVGA 1600 also using the 6 - 2+6 x 2 GQ cables from the EVGA 1000 (note G2 cables dont work with the EVGA 1000)
i am undervolting (1650W total) and checked the thermal image of the rig using a FLIR professional instrument, no probs (aside from a component on the mb but thats a discussion for another thread)
