Weird computer behavior during a split second of a power outage

[VoltaIsFuture]

When there is a power outage for a split second, computer does not turn off. It just restarts itself, and i see the windows boot log, computer boots up and everything works normally from there, is that normal??

I would think so, I've never had a desktop running during a power outage so I wouldn't really know for sure

mine has done that a few times. 
It can cause some issues especially if you were saving files or anything was being written to. 

So I try to run a chkdsk after every power outage.

Ya so it is normal for it to restart when it is only a split second of a power outage????

yes. desktops dont run on battery unless you have a UPS (uninterupted power supply) to keep it on during poweroutages.

Yes, it's probably a safety feature of the power supply since the capacitors can only hold so much charge. If these are frequent you should buy a UPS to prevent damage to your system.

this can happen sometimes. some systems are more immune to split second power outages than others. like this one time my main system rebooted while the old computer that i used to serve files and printers to the network didn't even notice something happened.

If power outage happens often and you are afraid of losing data, you could buy a power bank or whatever it is called where it keeps a computer running until you do save shut down in a case of power loss. I only saw such thing once in my life ages ago, not sure if people are actually using this at home.

i think most people who know those things exist still don't use one at home because they tend to be expensive

Ya, at my house my bro's pc does shutdown during a split power outage but my computer  just restarted itself!

Ya but in my opinion if you are buying a  computer that costs over 2 grands then it is worth it to buy a UPS

yeah, but this "server" i had didn't even skip a beat while most other devices running in the house at that time reacted to the outage in some way. almost creepy

Ya, i dont know. Me and my bro have pretty similar rigs, except he has a regualr PSU and i have a 80 + bronze PSU. So i really dont know.
