I run my antminers in pairs of 2 connected to corsair rm1000's.
Power at the distribution unit where the power supply plugs in is: 3.6A~750watts @ 208V power.
When you purchased the 1000 watt corsair to power 2 antminers, did it come with 4 PCI-E cables, or did you have to purchase them separately?
That's the beauty of this power supply! It ships with 4 cables, each has 2 PCI-E connectors for a total of 8 connectors. Plus, it has 83A on a single 12A rail. Some engineer at Corsair must have been a miner! lol
