I believe GrapeApe is using the EVGA 1300 G2 without issue. You just need to split the multi connector pcie cables over multiple blades so that each cable is carrying an equal load. At 1200 watts, that would put around 200 watts on each cable. In this configuration, each blade will have one single connector pcie cable and 1 half of a a dual connector pcie cable. This will only work on PSUs with a shared rail on the pcie output.
Correct I am using 1 EVGA 1300 G2 per Prisma. It has 6 PCIe cables 2 of which has double connectors. I am using the stock power cord with no issues. Phillipma1957 is suggesting making it a bit more efficient with a larger power cord.
