Windows 10: Computer Peripherals lighting up after just plugging in the psu

Hello! I'm kind of worried cause it never happened with my computer before.So i just changed my mobo Gigabyte GA-H510M-K-V2 LGA1200 DDR4 mATX - putting this info cause it might be the problem. My previous mobo died cause of power surges .And so, after changing it I noticed that all attached peripherals are lighting up after plugging the psu cable on a ups or an outlet. I still haven't turned on my pc so I'm kinda worried if there's something wrong with my new mobo or my psu. There's no any burning smell on my pc and when I turned it on, the temps are the same as usual. I've also removed th

Office And Light Gaming Build

There's nothing wrong with the build, but I have some suggestions to, IMHO, make it better:

• You list a 550 watt PSU, but you have a 51 watt CPU and a GPU that pulls 120 watts at the max. In other words, your system will pull under 200 watts at maximum load, which it sounds like will be rarely. PSU's are most efficient between 50-80%, and even at max load, this system won't reach 50%. Suggest a PSU 400 watts or less, like the Seasonic G-360.
• RAM's really cheap. Suggest getting 16 GB instead.

 

What PSU should i get?

I find NO specs on the psu you listed, not the one ktr listed, ktr also suggested i get the mushkin psu!
