I'm awaiting an order of six Sapphire Radeon RX Vega 56 Nitro+ graphic cards which, unfortunately, need 3 x eight-pin PCIe power connections each.
I believe the rig should be fine if powered by two 1200w PSU's and am just trying to figure out which to order.
If I can get away with the Corsair HX1200i, I'll go ahead and order two of those:
Alternatively, I'll splash out the extra cash and go for two of the EVGA SuperNOVA 1200 P2:
The second PSU above seems to have an extra PCIe slot available.
I'm new to this but would I be okay to power three cards off each HX1200i? I'd use a 6 pin periph slot on the PSU for each of the risers. One of the eight pin slots would be needed for the CPU and five leftover would be used as follows:
1: To splitter and onto GPU 1 slot 1 and 2
2: To splitter and onto GPU 2 slot 1 and 2
3: To splitter and onto GPU 3 slot 1 and 2
4: To splitter and onto GPU 1/2 slot 3
5: Direct to GPU 3 slot 3
After reading some online advice, I cancelled my order for 18AWG splitters and placed an order for the 16AWG splitters below (at more than triple the price
):
