Is it possible to adapt this PSU to fit the older style S4?
Not with the PDI connectors but with the ones fitted with a nut and bolt?
Yes. 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

Oh OK so you take the cables from the original PSU connect them to the board in the picture - how using the screw connectors shown in the picture?
Then connect the PCI cables into the board?
Does this board come with the PSU as standard?
Thanks?
