I think his point was that he had other power issues. Those issues were likely causing small voltage fluctuations and perhaps even drop-outs.
We have 220 (110-0-110) 100 Amp service as well. With all the shop equipment and computer mapping equipment it's touch and go when appliances kick in and the motors spike.
Those are the things you worry about.
There is no reason the supplies recommended could not run on 220V lines -- more efficiently.
Lots of my equipment can run on 220V and draws less current -- runs more efficiently and cooler -- and typically has slightly less power draw because of those improvements.
That aside -- you are correct --normally it would not be worth the effort to run 200 Amp service. Especially to service a device that only draws 600 -- 700 Watts nominal.
But -- it would be good practice to run your miner(s) on a dedicated circuit -- were it easily done.
fwiw
I have a huge farm, remember....and a home.... the service line is now seperate from the well pump, microwave, toaster,coffee pot, vacum cleaner...and every other electrical disruption.
It DOES indeed make a difference!
think he ment 20 amp line usa direct (only thing on it is asic gear) vs probably a 15amp with other clutter on the line. so if I had a 15 amp wire line I'd replace the wire to the next gauge up 20amp and 20amp breaker etc...maybe overkill ..just saying ..or at least that is what I did....... just in case...running a separate circuit in to the breaker box in the basement direct.
No I said 200 amp SERVICE line. The FAT MAIN line that feeds your home, direct from the pole!
My sub-panel is like 250 feet from the roadpole and main box.
I added service line from the pole to the home.
I had a substandard, temporary line, that was meant for construction use. I installed all this myself.... I do ALL my own work. Built my home.
after 12 hours on the new line...
The answer is Yes, a nice. very steady hashrate now!
a couple days will show better I think...
I was noticing that with every pot of coffee, the rate would dip, every vacuum, the rate would dip.....use the water....take a shower...the rate would dip....
no more.
In my studies.... frequency counts alot towards efficiency. This is yet another example. Let it have it's 60hz unwavered. (50hz in EU)
A power factor correction cap may do the same.... if you rent... or those backup power supplies.....
I dont have that option with so many machines...
