UPS

Thanks for your replies. I am still a bit undecided. Would also love to understand how you are using it? Are you indeed expecting power outages of more than 30 minutes and (if so) are you wacthing movies in these circumstances?

I am asking as I try to understand what device to pick. I am more worried about outages of a few seconds, which on its own will have the server being off (basically a tenth of a second without power will turn it off). Also, in case there is really an outage, it would be nice to have the server being shut down after one minutes without electricity.

Even with my excessive electricity consumption (my server has a 1000W P/S), it appears that the very tiniest UPS device would be sufficient for my needs. Is that a correct conclusion?

Well, you can calculate it easily (see the formulas above), if you know your power requirements and your estimated outage times you want to overcome.

To my usage: I use my ups in my home-office for my freeNAS storage server running 24x7 and in parallel for the phone system, router, GBit switches and my laser fax machine - all connected to it, so I do not miss a call / fax from my customers just in case.

I've had some power outages during the last years, most of them for a few minutes - some because of stormy weather and some because of some damaged bulbs that fired the safety fuse one or two times. I also have done some re-wireing in my house and needed to turn off the fuses to prevent accidents while working - during this time the office stuff run on battery for a half hour. So all in all I am happy with my ups. However, after 2-3 years the battery packs are wrecked and need replacements. I just bought some online and replaced them - easy stuff.
