Yet I have had many m20's die from their crap psu. So yes, they run well, but power supplies are also junk. They are bricks now because you can't get the p11 psu's anymore.
Could there be an issue with your electricity setup? The psu on this gear had more dust than one can imagine, the voltage was far from stable but usually within 190-220v, what is your ac voltage?
By the way, if you are interested in buying them from China i can help you locate some.
Hey I would be interested in locating one, or some PSU. I have an M20S, and also a whatsminer D1 which has a P11 on it. The M20S is running full power non-stop, but the D1 is not. Yes I understand the D1 is an altcoin miner but I mine DCR with it paying every day in BTC. The P11 on my D1 is toast, would love to find one. Thanks
