A well-equipped and compact mid-range microATX motherboard based on the 2020 AMD B550 chipset. Equipped with AMD AM4 processor socket. In addition to small overall dimensions that allow it to be installed in compact MiniTower cases, it is distinguished by the presence of a full set of up-to-date system / peripheral interfaces and a high-speed 2.5GbE Dragon RTL8125BG LAN adapter.

Works correctly with 4/6/8/12/16-core Ryzen 3/5/7/9 3000 processors with Matisse/Matisse Refresh cores (7nm) and Ryzen 4000 processors (Renoir core, 7nm). The manufacturer is positioned as a product of the middle price category, designed to create gaming and universal home configurations for connecting to high-speed cable networks. The ASRock B550M Steel Legend motherboard is equipped with a reinforced 10-phase digital power subsystem with additional aluminium heatsinks. Supports up to 128 GB of DDR4 RAM (4733 MHz), which is more than enough for any games and resource-intensive professional applications. Supports the connection of two M.2 SSDs, one of which is equipped with a heat sink and is capable of working with the PCI-E Gen 4.0 interface.
