I'm planning on using 2 x EVGA G2 750Watt PSU per Prisma miner; the 750W has 4 PCIE connectors - so 2 per hashboard isn't a problem.
If anyone is looking for a good deal Amazon has the best price currently; plus their MiR is good for 2 PSUs.
if that is a split rail psu it won't work. I have a 750 watter and it use up to 3 cables on the fourth it overloads. mine is a split rail model . check and see if it is.
