We have been informed that you can run most current generation miners on 277 volt power, without stepping it down. Does anyone have any information or insight on this?

The ratings should be on the device and in the manual and they will specify the primary driving side with some lower and upper limits and usually a frequency as well and driving the unit outside of these parameters is not recommended and can result in the malfunctioning of, and damaging the hardware.

bitmain apw12 psu reads 200-240volts this is for the s19 gen or current gen

avalon may be able to do more volts with the a1166 pro but I don't have a link for the psu

the whatsminer p21 psu claims 277 volts see link

so if you use a whatsminer m20s it should be okay

It depends on what do you mean by the current generation, if you mean the latest generation then that's wrong info, Bitmain's gears like the S19 and S19 pro won't run on 277 volts, Microbt M32 and most of the M30 series require 176-264V.

As far as I know, only the following miners work on 277V :

M10, M20, M20S, and M21S.

In other words, any miner that uses one of these PSUs p21 and P11.

Old gears like the Antminer S9 can pretty much use any PSU that has 10*6pin cables or more and outputs 12v, there are many 277V PSUs with those specs, so that is an option if efficiency isn't a factor.
