Well we had one of many power failures earlier this week and it seems some of my UPSs were taken out. I was only ably to get one computer running and every time I plugged in one UPS it would kick out the socket (I do have to get that ground fault plug replaced). Finally got one computer running : https://setiathome.berkeley.edu/results.php?hostid=7226971&offset=0&show_names=0&state=6&appid=. SETI came up with 2 GPU WUs and 1 CPU WU. I decided the easiest thing to do was reboot and after the reboot I immediately started with downloading 198 GPU WUs. The after they had downloaded I got 99 CPU WUs. No problem downloading or getting WUs it seems..........HOWEVER I now have 300 abandoned WUs. Obviously something went wrong in the computer. At least I do not have 300 ghosts and all those WUs are now back in the mix.
(I can not wait until I get a new cooler in for my main system, seems turning off the Water Cooler has caused it to fault, not sensing the CPU fan, and see what surprises it will have for me)

UPSs do have a tendency to blow breakers after a power outage due to the fact the battery is dead. Say under normal use you are drawing 10A, but after an outage you are drawing 10A plus charging the battery, so poof goes the breaker. So let it charge up.

Cheaper UPSs are also known to never come back after an outage. They go to battery and never come back.

I have the UPSs set to power down the computers after one minute of power loss as our power outages can look like someone clicking the light switch off and on because we are on a power loop, one side down and the other kicks on.
My UPSs are APC.
