AMD driver version :- 20.1.3
CPU:- R5 3600
GPU:- MSI RX 5700 MECH EDITION
RAM:- G.Skill F4-3200C16D-16GTZRX (16gb) (3200mhz overclocked)
SSD:- Adata XPG Gammix S11 Pro 256GB
PSU:- ANTEC NEO ECO MODULAR 650 WATT 80+ BRONZE

Check the GPU power cables too, make sure the aren't damaged. Sometimes if too much power goes through them they can start damaging the cables, especially check the end that goes into the power supply. The part that plugs in that holds the 6 or 8 cables can melt and damage proper contact. This happened to my RX Vega 64 wave and Seasonic 1000W platinum power supply which I had for 3-4 years. It only damaged the cables at the PSU and I kept getting signal loss. Since getting a new Corsair HX850 PSU I've had no issues.
It's unlikely what is affecting your GPU but you never know and worth a check.
