  1. Eric

    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.

    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

    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…

  5. mike s.

    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. **Fun fact, Did you know most graphics card have a audio chip? I had to route my sound through my HDMI cable to my monitor and plug my speakers into it.** 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…

    Overall Review: Wifi works great! Also this thing is tight fitting because its itx obviously but it is legitimately tight to work in if you got larger hands. BIOS is simple to use for even beginners and AsRock has always been a good bang for your buck in motherboards. I do wish the backplate stayed in place better when putting the cpu on because it can kinda be a pain when doing it alone.

  7. Buff

    Pros: -For the most part, was extremely easy and pleasant to build on. -The quality feels very good, and you have some “premium” features with the low price like the NVME drive heatsink and WIFI, as well as OC options. -Bios is very beginner friendly, was able to easily overclock ram. -Detects boot drive instantly if powered on while inserted. I didn’t know how much I would appreciate these little things until I experienced them. -Plenty of fan headers for future expansion, and enough SATA…

    Cons: The m.2 screw is not standard because it secures both the m.2 drive and the heatsink that comes with the board. This means you have no choice but to use the heatsink which was fine with me. Overall Review: It was a relief to see the sticker for Ryzen 5000 support on the box. I did not have to flash the bios to get it working with my 5600G. Was able to install win 11 by enabling amd ftpm, TPM and secureboot. The xmp profile I selected is stable with my patriot viper memory.
