OK, good to know. And hypothetically, if I used this G1600, how many watts would be on each cable? 1200W/8 cables = 150 per cable in that case? Or is it not that cut and dry?

So the stock EVGA 1300 G2 won't work unless we change the stock cord? I am going to try to use a LEPA 1600w which is 15 amp (180W) per PCI-connector and it has 8 of them. (30 per socket x 4 rails (total of 6 rails on the PS) 12v3-12v6. Is it enough power for the Prisma? I am thinking yes, because 12v x 30amps = 360w. Anyway, I will let you know....

I run two S3s which are 340w on each of the 3 socket on the Lepa G1200, so I think I am good to go here.  (I run a total of 6 S3's on each Lepa 1200W)



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.
