Pretty sure this was my 2nd choice when I was looking for a B850M board. I can't remember for sure, but at the time, there was an MSI board that was only available overseas, and this looks a lot like it and if I remember correctly, that board only just recently became available in North America. The main deal breaker I had with this board, and it shouldn't stop anyone else unless they have similar concerns, is that I didn't like the idea of having my drives underneath the GPU. Between the heat of a 5090 and whatever gets produced for a gen5 NVMe, I had my concerns about the two adding heat to each other.
I also found it interesting about the 12+2+1 configuration, but at 60a per stage. One of the more unique configurations I came across when researching smaller boards.
Otherwise, for users who don't have extreme needs, it looks like a nice board. Plenty of fan headers, 2 drives, lots of ports, and a good selection at that and okay price given what AM5 micro boards go for on average. Generally speaking, I usually prefer MSI boards as I've had some pretty good experiences with them in my AMD builds (except for some odd BT/WiFi driver issues here and there).
