So I was just doing some browsing...
If I went with the APW3-12-1600-B2 on 220V to power an S9... How many would I need?
One has 5 6pin connectors. So you need two of those PSUs to power one S9 right?

Also I got confused,, the site said "Separate power supply to control board: there is one additional 6pin PCI-e connector on the IO board which must be connected to the PSU to get power.".
So does that mean you need a third PSU just for the board???
Or do you just put your one left over cable into it?


What powersupply would you recommend? (Preferably under $250)
