This interests me as well. I have an Antminer too & I let it collect dust(not in the good way) for 2 months assuming that when I moved my new house would have a 220v in the garage or something. It didn't, still doesn't as the cost to run one was far greater than just buying a EVGA 1300 G2 to run off 120 for the time being.
Now I'm looking at running another 2-3 miners, possibly 6(in my dreams) one day & to be honest I'll probably just move & find a place that already has some of what I want already done.
Obviously I'm not going to find a house prewired with a bunch of 10AWG to the basement, but an extra 220v or 2 would be a start. That being said & not to hijack your thread here but it is better to run 220v server PSUs than a bunch of say 1300 or 1600watt EVGAs? It's the kind of problem I'm ok with having, it could be worse, but I too would like to know what people with multiple 4-10 rigs/miners are doing for power.
There's got to be a limit. Some would be due to their power company bumping them up a tier but aside from that if I wanted to run 20+ rigs it'd probably make more sense to lease a building specifically for mining.
Essentially, your power consumption is going to be directly related to the mining equipment consumption. If you have EVGAs, they run at around the 110W realm. The power supply and delivery is as newton's physics states: The path of least resistance. If you run the Antminers, they are like having a 800W Hair dryer running full time.
Ever load an outlet too much? it pops the circuit to avoid overloading the wires, which could heat up or cause spark inducing a fire. So... YES it is much more efficient and safer to run at a 220 - 240V PSU to deliver your high order of... 1600W, 2400W, 3200W of power.
I know people are running multiple miners, so hope they see this thread and shed some experience.
