Great motherboard with lots of I/O. The LTT motherboard tier list places this at A-tier and has sufficient VRM and power delivery to support my 5800X3D without holding it back.

MSI B550-A Pro has 10x 46A 4C029N/4C024N discrete MOSFETs for VCore and 4x for SoC, in doubled/teamed configuration for 5+2-phase VRM, fully heatsinked.

It has an internal USB 3.2 Gen 1 USB-C front panel header in case your case comes with a front panel USB-C port. It also includes a rear USB-C 3.2 Gen 2 port.
