I will add that in a commercial 3-phase setup all the above run perfectly on the typical >208VAC you get across the phases. Most of my ~18 or so kw farm at work runs on it.

+1, all my high voltage PSU's specify 200V as minimum, just like Bitmain. In regards to the PSU's I offer, I find the 2880Wbetter for 2x S9's than the DPS-4K. It puts the PSU at an efficient yet healthy state of load, very reliable, compact and easy to mount with 24" cables. Only challenge is noise and 200V AC input.

The only difference 220V will make vs 240V is it will require slightly higher amperage (~9%) to provide the same wattage.
