MSI B550M-A PRO
 | Outdated Product £159.49 Compact, affordable and well-balanced 2021 multi-purpose ATX motherboard with AMD AM4 socket and mid-range B550 chipset. Refers to products of the MSI PRO-series family, designed to complete high-performance universal office systems, home PCs and entry-level low-cost workstations. Compatible with 4/6/8/12/16-core Ryzen 3000/5000 (Vermeer/Matisse cores, 7nm) and Ryzen 4000 hybrid APUs (Cezanne/Renoir cores, 7nm). Supports installation of two DDR4 memory modules with a total capacity of up to 64 GB, which is more than enough for any household, most complex professional tasks, streaming and demanding games. Thanks to the reinforced PCI-E x16 slot, MSI B550M-A PRO can handle massive and large discrete professional and gaming graphics cards. The high-speed PCI-E Gen4 system interface allows you...to significantly increase the speed of loading textures into the local memory of the video adapter and speed up data exchange with top-end NVMe SSDs. It is also worth noting the presence of a Realtek 8111H GbE LAN network adapter and two digital video outputs (HDMI, DVI-D) used to display an image from the video core built into the processor. Only high-quality components are used in the design of the board: durable capacitors, power switches with low heat dissipation, case chokes and textolite with a double thickness of metallization. |
