3.0 out of 5 stars Hay que actualizar el BIOS antes de Ryzen 5000
Reviewed in Mexico on December 22, 2020
Un punto a notar aquí es que no viene lista para un Ryzen 5600X batalle para conseguir otro procesador y poder actualizar el BIOS, no entendía el porqué no booteaba y se quedaba en la pantalla de ASUS y averigüe que ocupaba eso, otra cosa es que los indicadores de las conexiones del gabinete son confusas para alguien que apenas empieza, por lo demás todo bien, buenos materiales y buen funcionamiento al día de hoy, tiene varías conexiones para abanicos ARGB.

Reviewed in Singapore on January 7, 2021
Using a Ryzen 5 3600 with it. So far so good! It wasn't my first choice of motherboard, but due to the lack of availability of other B550M motherboards during my purchase period, have settled for this one. Comes with Dual M.2, PCIe 4.0, 1 Gb Ethernet, USB 3.2 Gen 2 Type-A. Hope it lasts.
