What Size UPS Do I Need For My Computer?


It's dark all of a sudden. Did this ever happen to you?

Screen Dark, Data Lost?
Not For Me – Thanks to UPS



Did it ever happen to you? You are working on a complicated spreadsheet on your computer and all of a sudden… power is out. The screen gets dark, silence follows, and you might hear your neighbor through the wall shout out loud, “Oh, shit!”



I got used to those power outages lasting from 30 seconds to 1 hour. Like during the recent heavy rainfalls in early December. In 95% of all cases power comes back in less than 5 minutes.
  • Other people suffer data loss.
  • Some people even had their hard drives crash or other hardware damaged (Ouch!)

I am not one of them.

After moving to the Canaries I quickly realized that electric power is not as stable as in the big cities where I lived earlier.

Therefore, I got myself a UPS (uninterrupted power supply), a kind of a battery that keeps supplying your PC and monitor with juice even when power fails. Usually you can run up to 15 minutes on battery power with your normal PC or Mac setup.

The reason for writing this article is I want to share with you what I have learned about UPS during the last three years. I just replaced my UPS with a new one because the battery died.

Update: Just added a “How To Video” going through the process.
