AM5 mATX motherboard with PCIe 5.0
The ASUS B850M MAX GAMING WIFI uses the AMD B850 chipset on a micro-ATX board. It accepts Ryzen 7000, 8000 and 9000 series processors in the AM5 socket. Four DDR5 slots support up to 256 GB at speeds beyond 6000 MT/s via AMD EXPO. The board includes Wi-Fi 6, 1 Gbps Ethernet, 7.1-channel audio and rear USB 10 Gbps Type-A and Type-C ports.
Builders who want compact AM5 with PCIe 5.0
This board suits small-form-factor gaming or workstation builds that need a full-length PCIe 5.0 x16 slot and a PCIe 5.0 M.2 slot driven by Ryzen 7000 or 9000 CPUs. It also provides three additional PCIe 4.0 x1 slots and four SATA 6 Gb/s ports. Users requiring more than four memory slots, 10 Gbps networking or a full-size ATX layout should look at larger platforms.
PCIe 5.0 x16 slot and M.2_1 at 5.0 x4
The single specification that decides compatibility is the PCIe 5.0 x16 slot and the M.2_1 slot running at PCIe 5.0 x4, which are only active with Ryzen 7000 or 9000 series processors. With Ryzen 8000 series CPUs both interfaces operate at PCIe 4.0 speeds, so CPU choice directly determines the peak bandwidth available for graphics and primary storage.

Questions about this item
Which CPU must I already have for the AM5 socket on this B850 board?
A Ryzen 7000, 8000 or 9000 series desktop processor fits the AM5 socket.
Will my PCIe 4.0 graphics card run at full speed in the primary slot?
With a Ryzen 9000 or 7000 CPU the slot is PCIe 5.0 x16; with Ryzen 8000 it becomes PCIe 4.0 x16, so a 4.0 card runs at its rated speed.
How can I confirm the DDR5 memory is running at the rated 6000 MT/s after build?
Enable AMD EXPO in the BIOS, then check the memory frequency in the Q-Dashboard or Armoury Crate software.
