This happens multiple times a day, all usb power ( mouse, keyboard, headphones, pc fans, cpu cooler fans, bluetooth) turn off for a moment then restart. im using an msi b450 tomahawk. The monitors are unaffected. So far it hasnt happened to me while playing a game but usually happens while browsing the web

full system spec? include brand and model of the psu

what exactly were you doing when it happen?
bequiet 500W system power 9, ryzen 3 3100, corsair vengeance RAM, coolermaster liquid cpu cooler 360mm.

I wasnt doing anything that could've caused excessive power draw, just watching youtube or some video. I've noticed now that it doesnt really happen when my pc is idle across the room, so it must be caused by me doing something im just not sure what
