I'm using a Corsair RM850 to power 2 Antminer S1. I found this to be the sweet spot in price/amps with very high efficiency.
The 2 S1 miners pull 730Watt from the socket.
A bit strange is that this PSU comes with 5 sockets for PCIe/CPU connectors. There are 3 double PCIe 6+2 cables and 2 8-pin CPU cables.
You can easily use 1 dual PCIe cable for 1 S1 miner. Ideal you would get 1 extra cable and connect 4 single PCIe cables for 2 miners.
A 1200W CPU should be able to run 3 of these things.

You need 35A on 12V rail per S1 miner to be safe.
So 70A PSU for 2 miners and about 100A PSU for 3 miners ...
If you're going to overclock, you'll need 40A per miner.

Yeah i was waiting for a reply on my post about the PS3 PSU so i was quick.

I understand that it's not good to use all the power because that will stress the PSU.
3 antminer's should be fine, maybe the fourth will be a bit much for that expensive PSU.

3 sounds good,thx mate
