ASRock B650M Pro RS WiFi

This microATX AMD B650 motherboard is aimed at compact AM5 builds using DDR5, especially Ryzen 5 or Ryzen 7 systems. It provides three M.2 slots, PCIe 4.0 x16 graphics connectivity, and 2.5 Gbit/s Ethernet. Buyers still need to check case fit, memory qualification, lane sharing, wireless needs, front-panel support, and the CPU support list before purchase.
