    BIOS is easy to use and has features that will satisfy everyone, except maybe some enthusiasts. RGB is tasteful and VRMs are legit. They are supposedly the same as the B450 Tomohawk without the top vrm heatsink.

    The lights on the MB are full RGB, controllable with Mystic Light.

    One of, if not the best, VRMs on the MicroATX Boards, along with two M.2 ports, four fan headers and two 12v RGB headers. Nice clean design and tasteful RGB lighting. No issues with the board at all.

    Ive always had a good experience with msi boards, the bios is super easy to use and overclocking was really easy and was able to get my cpu and ram to pretty high speeds!

    I was able to snag this for under $100 on Amazon during black Friday deals. Very easy to work with and the bios was super simple to use. You won't see too many micro ATX B450 motherboards available, this was one of the few that caught my eye right away and the price was too good to pass up.

    A great looking, highly reviewed motherboard (VRM's are best of any mATX AM4 board). I've also successfully used the flashback option when I broke the BIOS playing with memory profiles. Having 2 NVMe slots helped me decide on storage plans as well.

    First B450 to get stable bios + mATX. Great VRM, overclocks RAM perfectly.

    Design of this board is among the best in the B450 lineup; the BIOS looks the best when compared to other manufacturers. Great VRMs and overall a great mATX motherboard.

    Fantastic mATX board with tons of features. Easy to set up and use. Could do with 1 extra fan header.

    No issues so far. I think it's a good looking board. BIOS is easy to use, it already had a profile to support my 3200Mhz RAM. Literally a flick of a switch and it's running at full speed.

    Good board, though I have not tried overclocking. The port selection is complete and the VRM heatsink is substantial.
