What type of Temperatures are you showing for your GPU card and Ryzen CPU?
Check Device Manager and check to be sure you are not having any driver errors or yellow exclamation marks.
Run DXDIAG and see if any errors pop up. If you have a chance, Attach DXDIAG.txt to your reply.
Stress test your GPU card and see if it passes or shows any errors or problems. I personally like using OCCT. I would stress test your GPU and CPU first and then stress test your PSU.
See if you notice any overheating or PSU output issues during the stress testing of the GPU, CPU, & PSU.
