I'm looking to use a non-PC power supply, with regulated high current 12v DC.
Does anyone know (from measurements, specs) what the DC Current draw of the Antminer S1 is?  (Standard or overclocked?)

Is 12.0v the ideal input voltage, or would it prefer 13.5v DC?
(Is there a DC-to-DC converter in the unit, or does it need 12.0v?)

Do all S1 units need a total of six positive leads and six ground leads (for screw terminals)?  I want to have the wiring ready for arrival.

Thanks!
