Micro ATX motherboard for Ryzen 2

The ASUS Prime B450M-A/CSM is a microATX board built for 2nd generation AMD Ryzen processors on the AM4 socket. It targets system builders who need a compact foundation with corporate-grade lifecycle support and advance replacement coverage. The layout fits smaller chassis while keeping essential expansion and connectivity intact.

Builders needing long-term stability — not extreme

This board suits offices and integrators who value a guaranteed long product lifecycle and complimentary advance replacement over enthusiast voltage headroom. Buyers who want multi-GPU configurations or the highest memory overclocking headroom should look at something else, as the microATX form factor and B450 chipset limit those scenarios.

NVMe M.2 slot for primary storage speed

A single NVMe M.2 interface provides the fastest onboard pathway for the operating system and applications. The slot connects directly to the processor, so storage throughput depends on the installed Ryzen CPU. If a build requires multiple high-speed M.2 drives, this board cannot accommodate that need.
