Hey everyone. Wanted to reach out to see what you guys think about using 277v for mining. I currently am using a step-down transformer to 240v, but I wanted to build out a little section for testing some machines at 277v. I know HP makes some power supplies for 277v and I am going to give those a shot with some breakout boards, but I wanted to see if anyone has had any success with other power supplies.

IBM 2880 Bladecenter
I have seen a discussion from 2015 here that talks about different power supplies that run at 277v and on that list is the IBM 2880. Link: https://bitcointalk.org/index.php?topic=1206101.0

I bought a couple of them and tried it on 277v for about an hour and it ran great. I was curious if anyone has tried it long term. Also, why does this power supply work for 277v compared to other power supplies rated for 240v?

Bitmain APW3++ or Avalonminer Sorcerer PSU
Has anyone tried these power supplies with 277v? The sorcerer says it is rated for up to 264v so I am curious if either of these will run at 277v long term. Anyone had any success?

Anyone know of other PSU's that work at 277v safely?

It's not safe and not recommend mostly PSU's are related 110v/220v-240v above of that its not safe and it can damaged your power supply and your miner.
Transformer could help to step down to downgrade the voltage flow to 220v-240v and you can run your miner 24/7 safety.
everything too much is not good, it can result of too much hot in your miner and PSU and fried.
And don't forget to use surge protection for safety of your PSU and miner.
