Compact mid-range microATX motherboard based on 2020 AMD B550 chipset with AM4 processor socket. In addition to small overall dimensions that allow it to be installed in small Mini Tower cases, it is distinguished by the presence of a full set of up-to-date system/peripheral interfaces and connectors for connecting the Aura Sync LED backlight. Guaranteed compatible with 3rd generation Ryzen 3/5/7/9 processors with Matisse/Matisse Refresh cores.

The manufacturer is positioning itself as an affordable product of the middle price category, designed to create universal home and inexpensive gaming configurations. The design of the Asus PRIME B550M-A motherboard is adapted for self-assembly. It is equipped with a high-quality 8-phase digital CPU Digi+ Power Control power subsystem with an additional aluminium heatsink. It can work absolutely stably for a long time under a “heavy” multi-threaded multimedia, computational or gaming load. Allows you to install up to 128 GB of high-speed DDR4 RAM (4x32 GB), which is more than enough for any casual/professional software and current/future games. Installation of two M.2 SSD drives is provided, and one of them is capable of working with a high-speed PCI-E 4.0 x4 interface. Performant work in cable networks is provided by the Realtek RTL8111H controller.
