Very high-quality motherboard, I am quite satisfied. The only drawback that really bothered me is the second slot for a graphics card at the bottom; I consider it a useless design choice, no one will buy this small motherboard to put 2 graphics cards on it (not to mention that the 2nd one barely fits if it's dual slot and it obstructs many cables from connecting). I would have preferred it to have another normal pcie 1x slot on top. Nevertheless, I chose it because it has 2 slots for CPU fans and another 4 for case fans, which was convenient for me since I installed one of the CPU fans and all 5 case fans directly on the motherboard. The only downside is that one of the 5 fans is controlled based on how hot the processor is, but it's a minor issue. Other than that, it has a quality, sturdy design with good cooling. It came with BIOS 3.20 and although 3 more have been released after that (the last 2 are beta), I preferred to stick with this one and not flash it yet. Anyway, it works perfectly, I have no complaints. I recommend it to anyone looking for a quality micro ATX; I combined it with a Ryzen 5600X and 48GB RAM Gskill 3200mhz and two M2 SSD ADATA Gen4 and the machine runs flawlessly.

My motherboard (traumatic experience) broke and I wanted to get something more than a basic AM4 and based on the B550 chipset instead of the A520, so that it would be both of slightly better quality and more durable over time. I ended up choosing this one because it seemed to have a very good price-quality ratio. This motherboard has many advantages, such as multiple fan headers (I connected 3, one for the processor and two 12mm ones for the case, and it detects them very well), 2x USB 10 Gbps (1x type A and 1x type C, the latter without display out and PD), triple display connections DP/HDMI/VGA, antenna headers, 2x M.2 SSD slots (1x PCIe4 x4 or PCIe3 x4 and one PCIe3 x2), M.2 slot for WiFi card, sturdy construction, countless BIOS settings for regular use and gaming, top DDR4 speed (4 slots), support for PCIe 4 peripherals (depending on the processor), and many more. Pay attention to which processor you will use because it does not support BIOS flashback! Mine came with BIOS v2.50 which supports all Ryzen 3000, 4000, and 5000 series, but check the relevant Asrock support page to see if it supports your processor. The technical manuals, software, and online support are very good. The motherboard is manufactured in Vietnam - I don't know if this is good or bad, but it seems to be a quality build. Its heatsinks look good, except for the one for the SSD - I think a larger one that fully covers it would do a much better job compared to the integrated "plate". Compared to my old motherboard, I think it is much better, but I don't consider it among the best (and much more expensive) motherboards on the market. However, I think it is very good for the money. I deduct one star due to the lack of BIOS flashback support and the inconvenient placement of the M.2 slot for the WiFi card.

CPU: AMD RYZEN 7 5700G
RAM: KINGSTON KF436C16RB1K2/32 FURY RENEGADE 32GB (2X16GB) DDR4 3600MHZ DUAL KIT
M2: SSD KINGSTON SKC3000S/1024G KC3000 1TB M.2 2280 NVME PCIE GEN4 X4
WINDOWS 11 64BIT.
The processor is not PCIE GEN4 X4 but 3. However, it doesn't matter. The only problem with this motherboard was that if I set the memory to 3600, the screen would go black and the machine would freeze after 15 to 20 minutes. I solved it by lowering the speed to 3533. Even though I updated it to the latest BIOS, it didn't work at 3600.
I play Grand Theft Auto V without any crashes and with much better graphics than the Gigabyte GeForce GT 1030 2GB GDDR5 OC.
I have installed 3 fans: one in the front (120mm), one at the bottom (120mm), and one at the back (90mm). I have them in silence mode.
The CPU comes with the fan that was included in the box. It doesn't have any temperature issues.
The motherboard came with BIOS 2.50, which works with all processors.
Also, please note that by installing an M2 disk, you immediately lose two SATA ports. This was one of the main reasons why I chose it because it has 6 SATA ports.

Good motherboard with more impressive coolers than its predecessor, which I also have, without, of course, having anything revolutionary. I miss motherboards with the panel that displays the error code and you don't need to learn Morse code...
A reset power button on the board wouldn't be bad...

Where they made a mistake for me is the backward compatibility.
It only supports Ryzen 3rd generation processors and above.
The R5 2600 that I initially tried doesn't work... and some APU from the 3x00G series may also not work, which are Ryzen 2nd generation.
The motherboard with an incompatible CPU won't even post and it just shows 2 blinking DRAM-CPU lights.
For the inconvenience, I would give it another star, but the reality is that I hadn't read the CPU support.
I just couldn't imagine that they wouldn't have included the microcode at least for all Ryzen processors, come on...
If you want the above compatibility, go for the older and cheaper B450, which practically performs the same and supports all processors for this socket.
