So a while back when I first build my first pc, I had a ryzen 1200, an rx580, and an evga b450t psu. Fast forward about a year later and all of the sudden I start getting random crashes in game, none of which were repeatable so it wasn't software. I had eventually determined it was my psu and just upgraded that. But my question is, on a system with barely 300w power draw, that was fine for the first year, suddenly not be able to output enough power the the components.
