There have been some reports of psu fails when volts drift above 243-246
Have you seen any more anecdotal evidence of PSUs failing with a voltage spike above 240v ?
I have been having problems with equipment at a colo (they have been dropping like flies) and the site has also been having significant electrical issues
No new info but I finally lost 1 psu about 2 months ago.
Our major issue is we drop to 190 from 220-227.
It has over amped a few psus. 1 Avalon died 1 s17 died 1 s15 died. I had spares. I now have 1 s17 spare and no other spares for the new gear.
