I am having a very hard time finding a concrete answer on if you have to use the molex connectors on the board if you are using powered USB risers, or not. Everything i find is just people arguing over it.
I am currently using a Corsair TX750M to power an entire 4x 1060 rig. I have two more 1060s and an ASRock H81 Pro BTC R2.0 on the way. I was planing on replacing the mobo, adding the 2 cards and using an EVGA PSU i have laying around to power the 2 new cards i am adding (And their risers).
All the risers i have on hand are molex. Since i am being told i cannot use the second PSU (EVGA) to power the risers of the new cards (only the 2 6pins on the cards) or the molex connections on the board. I wont have enough connections on the first PSU (Corsair TX750M) for the Molex on the board. I am already going to have to convert 2 SATA to Molex for the last two risers so they can be on the first PSU (Corsair TX750M).
Any tips would be very helpful!
EDIT: hmm according this i can power the riser and the GPU of the 2 new cards from the 2nd power supply? This is what i planned to do originally but i was told it was dangerous to not have all risers on the same PSU as the MB.
