Never hurts to be protected. I say a few expletives when the power blinks, surges or goes out. I use high quality power supplies when i build my computers. I have too much stuff to buy UPS's to protect it all so i rely on surge protectors on everything, some even have 2 together just in case. My old rental house that was built probably in the 50's had power issues and it took a lot of work to keep noise out. i looked at conditioners but couldnt really decide if they would do any good but that would have been a good house to try them in. No such issue's in this house .
