    For it's purpose, it's great. A M-ATX board that looks very clean and was very cheap. However, I might move towards a larger board. Definitely would recommend for a M-ATX build.

    Easy to build on and provides all of the features i was looking for! No update required either, ready to go right out of the box.

    Runs solid with a 2200G and has a great amount of ports/headers.

    My only complaint is that the I/O shield is garbage. While it's stainless steel, it's unpainted (which may clash with some black builds) and trying to fit the MB into it was the hardest part of the build. The HDMI port will also not output at 1366x768 (which I need for my TV) but I blame Windows for that, not this.

    High quality budget motherboard with future upgradability! Wish you could change the color of the lights on it though.

    There aren’t many options for micro-ATX AM4 boards, so competition is slim. But this board has been working well for me so far. Easy overclocking (although I’ve only overclocked RAM with it so far) and overall typical ASUS quality. Two fan headers, an RGB header, M.2 support, and 6 SATA ports (although worth noting that SATA ports 5 & 6 are disabled if you are using the M.2 slot).

    Update: I was having boot issues. If I would shut down and then turn back on without cutting power at all (normal shut down, not a restart, and leaving the PSU on), the system would hang on the POST screen until I hit restart on the case, then turn on. But, updated to the latest BIOS and this issue is gone.

    from completed build I Should Be Studying

    As a first time builder, this seemed great to work with. The manual makes that part easy enough, and there's really nothing negative I can say about it. There was a point where I felt that perhaps at this price point there may be better boards out there, but for a deal, this does exactly what it needs to.

    This is an excellent motherboard! Everything works well and was/is super easy to setup! Search function is very helpful because some of the options do seem a bit buried.. only because there’s so many options! Asus AURA works with 4 pin LED. Great board and competitively priced.

    This mobo is great for what i was wanting (had an m.2 slot, neutral black and silver design, and aura sync). Only complaint right now is that the dang IO shield sucks! I heard thats always a tough part of a build in general, but that was garbage trying to fit the mobo to the shield.

    Nice and efficient. It just works. And it works so good. No issues at all when updating the BIOS or drivers.

    from completed build Entry Level Sleeper Build

    Motherboard: The Asus PRIME B450M works perfectly with the case I chose. My only complaint is the yellow LEDs, although I know they can be shut off in the BIOS. This board gives me space for RAM upgrade ability in the near future.
