1 year later, and still keeping up.
Style: Steel Legend
I have zero complaints. I built a custom PC with mid-grade components to do some light gaming and internet use. This board is great. It doesn't support USB-C, but that's such a small issue in my book that I don't even see it as a problem. If you just have to have that, you'll need to look elsewhere. This is an amazing board for the money, and it looks really good in my white-out, see-through case build with RGB.

My only option
Style: Steel Legend
Bought to solve a power issue with my 4700GE ryzen processor. This board is able to deliver a consistent 7 watts to the cpu and eliminated my BSODs from the last board I had. Definitely recommended if you are replacing a ryzen Lenovo matx desktop mobo and have all the components to salvage for this one. It's hard to find boards that just work with OEM parts and I was happy this one did.

Incredibly Reliable and Budget Friendly MoBo
Style: Steel Legend
This motherboard came incredibly quick, literally next day, and it has worked amazing ever since I opened it out of the box. I paired this motherboard with a Ryzen 7 5800xt and GeForce rtx 3060 12gb gpu and I haven’t had a single issue with the motherboard since. The ARGB ports work amazing and connect extremely well with my controller and the rgb on the motherboard is perfect and not too bright. The RGB app (ASRGB Polychorme) is easy to work with and while it has a limited number of RGB options, they are good options that work for the everyday user.

This is an awesome B550.
Style: Steel Legend
Plenty USB ports, enough SATA ports, 2 Nvme.2 slots (second one is SATA and disables ports 3456), 1 m2 key. Worked right out the box, the chipset drivers are still a bit buggy due to its recent launch. I expect it to get better in a couple of months. Had a couple of issues with RAMs, but they are now fixed on the new BIOS update. Please select RAMs in the QVL list to avoid these issues, I had random crashes and windows corruption and found out it was due to RAM not being compatible with each other using the 4 slots (Team Group Nighthawk). The RGB is beautiful and I didn't have any problems to match everything together. The only thing the software didn't recognize was the GPU, but this is known with the MSI RX5700XT Gaming X. Totally recommended!

Es buena por lo que cuesta.
Style: Steel Legend
Me gusta, estéticamente es muy bonita, los materiales de construcción son buenos, tiene bastante disipación térmica. El único detalle, aunque no afecta mi calificación y que puede mejorar con una próxima actualización de BIOS, es que ya venía actualizada con la última versión de BIOS estable (la 3.90), sin embargo el arranque inicial hasta donde carga el logo de Asrock es bastante lento, fácilmente puede llegar a 30 segundos. No es problema de memorias, porque con 1 o con 4 módulos se mora lo mismo, incluso en configuración de fabrica. Pensé que podría ser el perfil XMP de la RAM pero no, tampoco en las batería del CMOS porque con otra tarda lo mismo. Sin embargo la board funciona bien, no genera problemas ana vez inciado el SO, solamente hay que tener un poquito de paciencia al prender el equipo.
