I've also learned the hard way to Google "AM4 main board tier list" before buying.

Some boards can run a 5950X in name only, while others can comfortably run it close to double its spec power all day. VRMs are a real differentiator for this tier of hardware.

(If anyone can comment on the airflow required for 400-500W Epyc CPUs with the tiny VRM heatsinks that Supermicro uses, I'm all ears.)
