Whoops, I need to correct my comment slightly, because Asus has so many motherboards: the Ryzen Pro is in an Asus Prime X370-Pro motherboard.
(There is no Asus 'Prime Z370-Pro', but there is an Asus 'Prime Z370-A' for current Intel CPUs so you can easily be confused just by changing a few letters.)
