Works as well as expected. 8/3/2020 8:35:16 PM

Pros: Price, up-gradable (future AMD chip releases), and fits in all setups.
***The ability to boot from the Gen 4 M.2 slot***

Cons: Sound issues and plastic PCIe release bar.

Overall Review: The Booting from the M.2 slot sold me on this MoBo. I expected the build quality and so on for the price. I installed the PCIe graphics card and had to remove it because something did not connect. When I was in the process of the removal, I could not hit the release bar. I had to use a very small screw driver due to lack of easy access. When I did this, I think the plastic bar cracked. But when I replaced the graphics card, I held with no issues and booted up right away.
I continued to update the drivers and Windows. Did some stress testing and called it a night. The next night I started to watch a couple videos and tried a couple of games. Turns out the sound card is not processing voices. The background music blasts out and the voice sound is like a mouse in the wind mill in a hurricane. I plugged it into the back out put and the front earphone out put. Still the same.
Hoping it's a software issue and will be fixed via an update in the near future.

All that and I still give it a 5 star because of the gen 4 M.2 booting. I am using a 3700X chip with a gen 4, 1 tb SSD and it took me less than 10 minutes to install Win 10 and every boot up after has been 8 secs for the ASRock logo to pop up and 4 more to fully boot.

"APPshop", "MotherboardUtility", and "RestartToUEFI" doesn't work but a good board 7/29/2020 9:28:30 AM

Pros: Everything, hardware wise, is working.

Cons: ASRock "APPshop", "MotherboardUtility", and "RestartToUEFI" doesn't work. They will install but when you try to open them it says "this utility is not for this platform".

Overall Review: If you're on a budget and want the latest chipset for a mitx build then get this board.

excellent value and performance 7/25/2020 1:44:35 PM

Cons: Not much of a con but the m.2 was a little difficult to install since the drive and the shield has to go on at the same time due to the screw placement of the shield but not to bad.

Wish it had extra usb ports instead of ps2 port.

Overall Review: Great board for the price, installed in lian li tu150, paired with ryzen 3600 and gtx 1080, does what i need it to no issues, plugged it in and worked. good looking board to, not to flashy. Im not a overclocker so I cant say how well it does I just play games, but overall happy with purchase and the price is amazing for a new b550 and mini itx

Easy to use, everything worked great straight out of the box. 7/23/2020 9:17:40 AM

Pros: - Test bench setup and posted within 20 minutes.
- Reasonably priced.
- Latest B model motherboard.
- Built in WiFi for a good price.

Cons: None so far.

Overall Review: Bought after multiple RMAs of a Gigabyte B450 paired with a Ryzen 5 2400G. Gigabyte board only posted with a graphics card, bought this ASRock board out of frustration, and had it working within a half hour with no headache whatsoever. Cannot recommend enough. It works exactly as you'd want, and expect.

Good motherboard 7/23/2020 8:54:35 AM

Pros: Felt and looked sturdy
not missing any features I wanted while being the cheapest b550 board at the time

Cons: The layout is strange

Overall Review: I really like the board and don't regret buying it, but I can't plug the front header audio in because of the awkward placement of the connector so my case wires don't reach. The power connector is also in a weird spot
