Hello,
Based on a short off topic exchange, it looks like there is some confusion about the best ways to hook up some of the current generation miners to popular power supplies. I'll be happy to edit this post as people provide information to provide a place to find this information quickly. Please don't limit it to what I've got here, feel free to add other miners and other PSUs, as well as helping me fill in the info correctly here. Also, most of my experience came on BFL and S1s, so please correct me if I've mistated something.
Antminer S5
CX750M - Will power 1 miner, connect the 2 - 8 pin split cables to the ports labeled "6+2 PCI-E & 4 + 4 CPU" and to the 4 - 6 pin ports on the miner ( ? )
EVGA 1300W SuperNova G2
Spondoolies SP20
CX750M - Need two PSUs to power 1 miner, connect the 2 - 8 pin split cables to the ports labeled "6+2 PCI-E & 4 + 4 CPU" and to the 4 - 6 pin ports on the miner ( ? )
EVGA 1300W SuperNova G2
Antminer S3
CX750M - Will power 2 miners, connect the 2 - 8 pin split cables to the ports labeled "6+2 PCI-E & 4 + 4 CPU" and to the 2 - 6 pin ports on each miner. One cable per miner ( ? )
EVGA 1300W SuperNova G2
I do not think the cx750m will safely power an s-5 running above freq 325.
but I am not sure. it only has 2 cables each with 2 plugs.
so you are asking the cable to do 300 watts if you do freq 350. So I guess the best way to know has anyone run a cx750m with 2 s-3's set at freq 225 that would be 1 cable for each s-3 using the 2 plugs one in each board. two s-3's at freq 225 pull about 720 watts so if you can do that the cx750m could certainly run 1 s-5.
