Our take on the Asus Prime B550M-A WiFi II AM4 3rd Gen Ryzen Micro ATX Motherboard

The Asus Prime B550M-A WiFi II is a micro ATX motherboard for AMD AM4 processors, built around the B550 chipset. It has four DDR4 slots, a PCIe 4.0 x16 slot for the graphics card, two M.2 slots and built-in Wi-Fi. It suits a compact Ryzen build that needs wireless networking without a separate card. Against pricier B550 boards it gives up some USB ports, fan headers and overclocking headroom, but covers the basics for a mainstream gaming or office PC.
