interesting, well this board is simply the best b450 board that you can probably get for 120ish bucks.
8 sic639's are absolutely more than enough for any am4 cpu currently, if you want to go for it, then that wont be a bad choice.
seems like it's a new board, i'm not familiar with it, but it looks similar to the b550m tuf plus.
if it is, then it uses 10 sic639's (50a dr mosfets) and 8 of those is for the vcore. the b550 one is pretty good, and if this one has the same vrm then it's a really good value.
the b450 mortar? if it's the same price as the b450 mortar, and it's vrm is as good as the b550m tuf plus, then definitely go for it.
im actually interested on why they released this board now, and why it's using the old chipset.
edit: yep, it looks like it's the same as the b550m tuf plus with the old chipset.
