I used to have a APC UPS, it worked fine for quite a few years but suddenly stopped working. I heard good things about Eaton, and bought one, but it has been a disaster to be honest. I use it on a fileserver, and the capacity should be good, but when i tried the new one from Eaton it cut power during startup, and restarted the machine several times, maybe some peak power thing, but the APC what 650VA, and the new one is 850VA and the APC worked fine. For some reason it caused some data loss, which is certainly a big drawback when preventing data loss is the main reason for having it in the first place. I had a power failure, and the Eaton seems to have handled shutting down the machine, but after the failure it trips the circuit when it is plugged in. Does anyone have some other UPS to recommend? As of know the UPSes has caused more power outages than just not having one.
I honestly got tired of APC/CyberPowr units either taking a complete shit (internal failures), or yeeting batteries every year or two.
I ended up building my own damn UPS, a few years ago.

I have tested with up to a 1,500 watts constant load, and it was able to power a 1.5kw load for around an hour and a half.
It should be good for 20 years or so. Expensive, but, damn, peace of mind is nice. Under typical load, it can power my entire rack from around 4-6 hours depending on load…
