i have some antminer s3

but i only have 3000W to mining

i need to have max efficiency

3000w/120volts=25amps
keep in mind that as you volts drop you watts go down and amps go up

curently at my house i get 117 volts. a good idea would be to put a volt meter on your plug to see what you volts are at different times of the day and different days.

117v * 25 amps = 2925 watts
115v * 25 amps = 2875 watts

do you have a 25 amp beaker. that seams odd. residential is usealy 15 or 20???

Sounds like they are from Europe (Portugal?) where the voltage is 240V, so that would be only 12 Amps.

By the way, where do I find what the stock voltage is?
