I have an asus b450m-a motherboard and want to upgrade my ryzen 5 2600 to a ryzen 9 5900x. I know the upgrade will work and is compatible already but i saw on other reddit posts something about the boards VRM isn’t good? is this true and should i upgrade my motherboard too?
 
Solution
As you are going to need a CPU and motherboard, I would suggest an i7 12700, over a 5900x. Performance wise they trade blows, but the 12700 is considerably cheaper. That way you have upgrade options.

The board you currently have lacks any cooling on the power delivery side for the CPU. I'd say don't bite the bullet and swap out the board for something like a B550 chipset with a beefy VRM cooling assembly.

Review of that cpu with benchmarks.

 
if you're case has good airflow, then i'd not worry about the passive vrm cooling. good airflow will take care of the needs. i am considering the same thing for my b450 aorus pro. it does have a heatsink on the vrm's but it stays cool now with a 3600x simply due to the nice airflow i have in the case.
