The Asus Prime B850M-A WIFI-CSM is a micro ATX AM5 motherboard built on AMD's B850 chipset. It pairs a 9.6-inch square board with four DDR5 slots, three M.2 slots, PCIe 5.0 for the graphics card, Wi-Fi 6E and 2.5Gb Ethernet. It suits builders who want a compact Ryzen 7 or Ryzen 9 system with current connectivity and room to expand. Against pricier X870 boards it gives up some USB4 and lane flexibility, but covers the essentials for most gaming and productivity builds.
