I'm in USA so 120 volt or 110 not sure.

What is the highest I can put my ASIC Voltage to without it breaking/popping any circuits?

Power cost is not the concern and I'm pretty sure the max power draw is 1300 watts from the AMP3++ power supply from bitmain?

I want highest hash rate possible... POWER cost is not a problem the only problem is popping a circuit!


Thanks

Your supply will only give you 1200watts at 120v. So you can't go much higher without killing the supply or starving the boards.

The above is correct but to answer the rest of your question : look in your breaker box. are they 15amp breakers or 20 or what..
take that and x 110 (thought technically 120/240 - real world best to base your math on 110/220)  this will give you  the wattage that
the WHOLE circuit can run..at MAX if your wires are crappy and barely acceptable for the amps you will be drawing they will get hot.. (gotter the closer you get to max..)  so lets say 15  so that is a max of 1650.. (oh wait keep in mind your psu will draw MORE than the 1200 it is giving to the machine.. by like.. alot. )  so realistically.. you can do it on 15 amp breakers IF you have pretty much NOTHING else on the circuit.. how to find out? flip a breaker.. what all went off... that;s all on the same circuit. voila.


my bad.. the rest of HIS question. sorry still getting coffee in me.

Actually, I clamped mine at the breaker and based on voltage at the time vs the amperage I clamped mine were using 1180 watts. That includes the power supply. So the power supply doesn't draw a "lot" more. The efficiency factor is printed on them too.

Wow I gotta get me some of those then.. I knew bitmain was good about power efficiency but damn.. (most psu's no matter what they "claim as efficiency isn't anywhere near it in the real world - I assume they base calculations on best case scenarios a million things will go into it in the end including dust on the fans etc..)  anyway so the miner is probably using say 900-ish of that .. when you start drawing close to the 1200 it will start using more (that last bit is almost exponential because the heat, voltage drop it will start drawing more.. so you should be good so long as you are keeping it under max.. they might have a chart of the draw at bitmain, you can probably figure where you will get peak performace from that.
