5.0 out of 5 stars Best motherboard for the price!
By Kyle Pommier on September 21, 2020
This was my first ever PC build with this motherboard and I am glad it was! You will get more than you pay for with this motherboard. It may be a micro ATX board but it has many features that some standard ATX boards don't even have! This board has 2 NVME slots which is very useful for extra storage. This board is one of the most best looking in my opinion. It has a nice black and grey contrast without any other flashy colors. That means that this motherboard will match with any PC theme you are going for. This is also a very easy motherboard to work with as long as you are careful with everything. This board was 3rd Gen AMD Ryzen compatible right out of the box, but if your motherboard's box doesn't say that on it then you can flash the BIOS. Flashing the MSI BIOS is a very easy process as there is a BIOS flash button on the motherboard and all you need is a USB stick with the bios on it. The manual is very helpful and includes everything you need to know. This motherboard is also B550M which is a big upgrade from B450M. I would definitely get this board again. Great price, good looking, easy to work with, LOTS of features, and more!

5.0 out of 5 stars MSI makes a good board.
By Ronald Bradford on November 16, 2020
PRO
I like the black color theme and aggressive style, the EZ Debug LEDs that show you what's not initializing correctly during POST, the 4 RGB headers (2 ea. of 12V RGB & 5V ARGB), and the inexpensive price.

CON
Some of you may need more features, but this is an entry-level price-point with some extras others might not give you at this level. MSI has mid, high, and top tier boards, as well.
