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?

Yes unless you want to risk damage the cards, or burn the whole place down. It's up to you.

Please beat this dead horse for me..
I bought a Y-Splitter, 8-Pin pcie to 2x 8-pin pcie.

No, I'm not advertising, I just want to be clear about my cables, because the whole .

Is it the PSU that will be causing problems or the connections on the cable that I've got? (or am I fine?)

I imagine that the problem would lie with the connection at the PSU end (where there is up to 250W going through those small wires), am I wrong? What's wrong with my thinking that a more quality Y-Splitter would be able to handle the wattage?

PS I've been mining about a week with two of these cables for 2 cards, and the other 2 cards using 2 separate cables each which came with the PSU (2x 8-pin to 8-pin). Am I playing with fire?

Using Y-spliiter for rx Vega is very dangerous. It can't handle the power spikes fluctuations, however you can use dual cerfified cable like the one EVGA has with 1 end 6+2 pin and the other end with 6pin and use a 6 to 8 pin adaptor

That's no different than using any splitter cable. The issue isn't splitting, the issue is overloading of the PSU cable.
