It's only worth buying if you're building an average home or gaming PC.
6 August 2020 
I've been using the board for a month now and everything is fine. The temperature at the power phases does not exceed 50 degrees, I thought the 4-pin power supply to the processor would not have much effect on its operation, but as it turned out, everything was fine. Ryzen 5 3600 processor overclocked to 4.2 Ghz. In terms of RAM, everything is fine too, I think 2 slots are enough for an ordinary user, 16 GB is enough for games, work and video editing. As for the audio codec and the Internet, everything is standard, no unnecessary functions or limits.
B550 chipset, good processor power phases, PCIe 4.0 support, board design.
4-pin power connection for the processor, as you cannot install Ryzen 7 or Ryzen 9 on this board and most likely this board is intended only for Ryzen 3 and Ryzen 5 3rd generation. There is no second slot for a video card, you can't enable CrossFire, but I think no one would install a second video card for such a price of the motherboard.
