Do you have a UPS? If you do, how many times has it saved your equipment? What was the scenario? (en.wikipedia.org)

My BX750MI-GR has saved my precious data on two occasions. Earlier this year, my seven year old, well used waffle iron shorted, popping loudly and sparking quite brightly in the process, probably because of all the gunk that had accumulated inside its less cleanable interior over the years. That not only made my breaker trip, but also blew the 16 amp main fuse. The UPS kicked in immediately, making a klick and a beep, which felt amazing. That was my first time ever.

As for the second time, see this post.

I have three UPSs.

Two at my desk: The smallest for my daily driver NUC, Eaton S3 850VA (510 W max) and enough for that purpose. The second is an Eaton Ellipse Pro 850 (510 W max) for my gaming PC. I want to replace both with a single device that has enough Oomph for both., but yet have to find a suitable model without fan noise at a reasonable price.

The largest is a APC SMT1000 that I got used without batteries, that I use in my rack for networking devices, some additional small devices, a Lenovo m920x and a custom build server (NAS, proxmox etc.). Usually the draw from the wall for that is 200 W. I added LiFePo packs instead of the Pb ones, as they are much more durable: 10 years instead of 2 to 3 years. As LiFePo packs have around 50 % continues load vs the Pb, the UPS ist purposefully oversized.

Where I live, we barely have outages, but they occasionally happen. Around once in two years. So it's more a peace of mind. Hard to say, how often they in fact 'saved' anything.

Edit: Edited battery chemistry to LiFePo. Did an oopsie there. Corrected typo.

    Sweet! I'm going to check to see whether it's possible to do the same with my little APC.

    I do recommend it, if the circumstances allow it. LiFePo are such a step up in battery technology.

    Just a tip for anyone considering it: Make sure to only use packs with an integrated BMS, as most of the shelves UPS models are designed for a different chemistry.

    Addendum regarding the desk UPS: I'm thinking about one of the power stations with a < 10 ms switch time. Have yet to find one that plays well with NUT.
