DPS-2000 + breakout board + S4's cables. You'll have to check if the breakout board has a limit per wire channel, I don't remember one.
Ohh dog-ie. You produce a pure loss for your owner Bitmain with your barking.
BITMAIN AntMiner APW3-12-1600 PSU Series hat is own separate power board to connect the PCI-E cables with S4 cables.
Named S4 Power_Board V1.0
No more S4 Power_Board V1.0 breakout boards with new PSU.
My last bought 4 x APW3-12-1600-B2 came without this breakout board.
And dogie does not work anymore for Bitmain, which of course is not something strange. .
Free land. dogie are now more committed to the Forum.
