Socket AM5 DDR5 motherboard for Ryzen 7000 8000 9000

This ASUS TUF GAMING B850M-PLUS WIFI7 board fits the AM5 socket and supports Ryzen 7000 8000 9000 series processors. Four DDR5 slots accept up to 256GB at 8000 MHz with EXPO and AEMP profiles. The 14+2+1 80A DrMOS design and eight-layer PCB deliver stable power for multi-core workloads and AI-ready builds.

Enlarged VRM heatsink M.2 heatsinks PCH heatsink

An enlarged VRM heatsink covers the 14+2+1 80A DrMOS stages while dedicated M.2 heatsinks and a PCH heatsink spread heat across the board. Hybrid fan headers and Fan Xpert 2+ adjust speeds to keep noise low during everyday tasks. The 2.5GbE LAN and WiFi 7 controllers run cool under typical network traffic.

PCIe 5.0 x16 slot PCIe 5.0 M.2 slot sustained

The single PCIe 5.0 x16 slot and one PCIe 5.0 M.2 slot maintain full bandwidth during extended gaming or compute sessions. Two additional PCIe 4.0 M.2 slots and a PCIe 4.0 x16 slot provide extra throughput without throttling. Rear USB-C 20Gbps and front USB-C 10Gbps ports sustain high transfer rates over long copies.

Questions about this item

How do I install a Ryzen 9000 series CPU into the AM5 socket and what step do people often miss?

Align the triangle on the CPU with the socket corner, lower the retention arm fully, then attach the cooler; many forget to remove the plastic socket cover before seating the processor.

Which components on this board will need replacement or maintenance over time?

The CMOS battery on the motherboard will eventually need replacement to keep BIOS settings and the system clock accurate.

What is the first limit reached when running the 14+2+1 80A DrMOS power stages under sustained heavy load?

The VRM temperature rises until the enlarged heatsink and fan headers managed by Fan Xpert 2+ become the limiting factor for continuous power delivery.
