Used this with 3400G for 2 months and then upgraded to 3600X. Supported both without any issue. Shoutout to MDComputers for updating the BIOS before shipping it to me. VRM is good enough for overclocking even when my room temps hit 35 to 38C. Pretty sweet experience for me as I was it was my first time with MSI products.
I just love this motherboard. If you don't want to do crazy stuff for overclocking just buy this board and it will do it for you. My Ryzen 3600 easily goes up to 4.1Ghz without even doing anything. This board also has an ample amount of fan headers which help you cool everything well. I haven't used all the RGB headers yet but I am planning to do so in the near future.
