I had none of these issues before unless I was hard overclocking which I am not. I have the Smart M. How do you know which is suitable?
So you spent quite a lot of money 3800x, 570 board,2080 and got a cheap and nasty PSU - did someone advise you on that ?
Every PSU in reality has a Tier there is a list here on the forum also. They don't mean that PC with low tier will not work at all, it means that it could be not suitable for a PC that is on some level by components. It's based on quality of internal components of PSU, how it behaves under load etc.
Your is "Tier D - Potentially dangerous, but only in specific situations" for your component most people wouldn't even think about that PSU. With 99% certainty I would say that PSU while under heavy load (or load that has high peaks) it not supplying enough juice and system crashes.
PS. Smart Pro RGB would also be good for your build.
