I've got two S3 batch 5s running off of one thermaltake smart M 850W. Each S3 has two pci-e plugs. Each S3 is running at about 216 GH/s.
I was under the impression that each miner could run with only two plugs each. Am I mistaken?
Under normal clock you need one power cable to each blade, sounds like you got two ports on one side powered instead of one each side
