Well-balanced 2020 ATX multi-purpose motherboard with AMD AM4 socket and mid-range B550 chipset. Designed to complete gaming systems, high-performance universal home PCs and entry-level workstations. Thanks to the reinforced PCI-E slot connector, it can work with massive and large-sized top-end discrete gaming video cards. It is positioned as a product of the middle price category.

Guaranteed compatible with AMD Ryzen 3000 (Matisse/Matisse Refresh, 7nm) and Ryzen 4000G (Renoir, 7nm) APUs. Unlike the previous generation models based on the B450 chipset), MSI B550-A PRO motherboard fully supports the high-speed PCI-E Gen 4.0 system interface, which allows you to 100% increase the speed of loading textures into progressive models of discrete graphics cards and speed up the exchange data with fast NVMe SSDs. With four DDR4 DIMM slots, you can install an impressive maximum total amount of RAM (up to 128 GB), which is more than enough for gaming, streaming and solving any household/professional tasks. It is also worth noting the presence of a high-speed network GbE LAN adapter Realtek 8111H and two digital video outputs (HDMI, DisplayPort).
