What exactly is the unit model of your ASIC machine?
There are ASIC miners that only mine at 200v to 240v less or more than that could damage any components in your miner mostly PSU due to overheating.
I suggest you try to use software to auto-shutdown the miner like awesomeminer to reduce the risk or to avoid burnt PSU or hashboard.
S9 and L3+, PSU are APW3++ on the s9 and APW7 on the L3+.
I have the S9 running on Hiveos and underclocked to about 960W and the L3+ on AsicFW.io underclocked to 670W. I also have the auto-shutdown enabled on both of them. I hope this will at least reduce the risks some.
