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.
The EVGA G2 750W has a single 12V rail.
Happy to report that this setup is working very nice; seeing around 1445-1460GH/s pulling 1195-1205W at the wall.
The Prisma had shifted a bit inside the foam padding, had 2 handles slightly bent (no damage to the boards) that had to be straightened a bit to be able to plug in the power connectors, the fan screws were loose & a screw was missing opposite side of the fan (found it in the box under the foam padding). Miner up and running within 15 minutes of USPS delivering the box.
Extremely pleased; thanks for organizing the GB CrazyGuy!
