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 a CyberPower 1500VA AVR UPS.

Some time ago, I had an electrical fault on one of two devices - either my Logitech Z906 subwoofer or a cheap power supply for a cheap monitor. Both failed at the same time and were connected to the UPS.

There’s a known issue with the Logitech Z906 where a pair of underrated resistors can blow. They had both exploded, and had also taken out a step down regulator elsewhere on the board.

So, the UPS seems to have failed to protect from an electrical fault of another connected device.

Hard to say how many times it has saved me from power surges and the like, I have everything expensive behind a UPS or surge protection so I don’t have equipment failures to compare against.

For the most part, UPS have allowed me to stay online after a power outage to tell my friends the power went out.

There were a few circumstances where my partner tripped a breaker and I was able to restore power without getting disconnected from a game.

    Nice! But, am I naïve to assume that my breaker already carries to role of a surge protector to some degree? I mean, it trips at a certain increase in current. I even learned how to check the response time of the individual "switches" hehe.

    Yes partly. Electrical extremes of various kinds threaten our gear. We have a storm right now, I live in the country, we are getting brownouts. Everything important is behind a battery and fast switching, I think. Lingering doubt, maybe I missed something or an appliance board could break, always there.
