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.
