Our take on the Asus Prime PRIME B850-PLUS WIFI AMD AM5 ATX Gaming Desktop Motherboard

The Asus Prime B850-Plus WiFi is an ATX motherboard for AMD's AM5 socket, built on the B850 chipset. It carries DDR5 memory, a PCIe 5.0 graphics slot, three M.2 slots, Wi-Fi 6E and 2.5Gb Ethernet, so it covers modern storage and networking without stepping up to a premium board. It suits builders who want a full-size board with room for several drives and a clean, understated look rather than RGB-heavy styling. Against pricier X870 boards it gives up some USB4 and lane flexibility, but it keeps the essentials most gamers and general builders actually use.

Questions and answers

Does this board support current AMD Ryzen processors?
It uses the AM5 socket and the B850 chipset, so it is built for Ryzen 7000, 8000 and 9000 series CPUs. Check Asus's CPU support list for the exact model before buying.
How many M.2 drives can I install?
There are three M.2 slots. One is wired for PCIe 5.0 and the others for PCIe 4.0, so you can run several fast NVMe drives at once.

Wi-Fi 6E is built in, along with 2.5Gb Ethernet. You do not need a separate network card.
What memory does it take?
It uses DDR5 DIMMs. Asus lists supported speeds and capacities in its memory QVL, and higher kits may need EXPO enabled in the BIOS.
