I have had a CyberPower CP1500PFCLCD UPS for a year and a half and has worked flawless. Every power event it has alerted me, worked as it should and configured to work. Pure Sine power factor correction. It's for the 3D printer/octopi server. Amazon blessed me with this one on sale $107 lightning deal

I've had power cuts where the Monitor and amp went off, but when the power came back a few seconds later, they both came back on and the PC, and the Nas, hadn't noticed a thing.PC-1

I got the Cyberpower, and it is indeed dead silent under normal operation. On battery power or when charging the fan makes a bit of noise, but in those conditions it is not an issue for me. Interesting feature is that you can switch off the audible alert completely,convenient for home use.
But the cause of the psu issue has probably been found: on of the electronic dimmers (gira knx dimmer) in the appartment started failing. I know that dimming leds can introduce some harmonics, so probably a failing dimmer can really mess up the power quality. Even though the ups does not show anything wrong with the input power, the computer hasn't shown the issue since being plugged into the ups...Comment
