Who each one is for
The ASRock B650M Pro RS is the one to take for the most affordable current-generation AM5 builds, though it is not built for anyone who wants Wi-Fi included out of the box and builds that want a PCIe 5.0 x16 GPU slot. It also earns its place with builders who don't need a PCIe 5.0 GPU slot or built-in WiFi. Buy the MSI PRO B650M-A WiFi for Micro-ATX cases where a full ATX board won't fit, though it is the wrong buy for any sustained overclocking beyond stock Ryzen clocks. It is equally the pick for budget compact AM5 builds that don't need more than two M.2 slots. It is the wrong buy for builds that want PCIe 5.0 storage or a third M.2 slot.
