Hello,
I'm running a small ASIC operation where I live, and unfortunately we have consistent power outage daily that last for a few hours. And sometimes the voltage drop to 180V for a part of the day instead of the standard 220V.
My question is, will this affect the ASICs long term? I have had them running for a month now, and nothing major happened, except couple of fans failure (which I believe because of their quality).
The stability of the voltage is very important to the power supply. If the voltage is often unstable, it will damage the power supply. I suggest you find a way to solve this problem, or change the venue.
