My power just went out but luckily I have a battery backup on my PC. Up to 30 minutes or so of use even with no power. Main reason I have this battery backup is so I don't lose work when power flickers. It's such a good feeling to suddenly stop hearing music, be kicked offline for a minute or so, have to reset my alarm clock, wait for the router to reboot BUT my PC is 100% good to go with no interruptions. The only thing plugged into my battery backup is my PC. Everything else is secondary and just goes through a surge protector I have. If you don't have a battery backup I recommend getting one. They are so convenient.
