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?)

Well P = V * I

So (roughly)

(stock)
360 = 12 * I
I=360/12
I = 30 amps

(overclocked)
430 = 12 * I
I=430/12
I=35.8 amps

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.

The terminal blocks have three leads per polarity on each blade. So you will need a total of 3 for positive and 3 for negative for each blade.

They now have the pci-e 6-pin plugs which if you have some spare extender cables to sacrifice is a much better way to fly. you need two per unit (one per blade).
