Socket AM5 DDR5 platform

This ASUS TUF GAMING B850M-E WIFI motherboard fits AMD Ryzen 7000, 8000 and 9000 series processors in a micro-ATX form factor. It targets builders who want a compact board with current connectivity for gaming or AI workloads. The AM5 socket supports future CPU upgrades without a board change.

8+2+1 80A DrMOS power stages

The 8+2+1 phase design uses 80A DrMOS stages on an 8-layer PCB with alloy chokes and durable capacitors. ProCool 8+4 pin connectors feed the VRM while an enlarged heatsink, M.2 heatsink and PCH heatsink dissipate heat under sustained loads. Hybrid fan headers and Fan Xpert 2+ keep airflow matched to temperature.

PCIe 5.0 x16 and M.2_1 slot

One full-length PCIe 5.0 x16 slot and one M.2_1 slot running PCIe 5.0 x4 are wired directly to Ryzen 9000 and 7000 CPUs. Ryzen 8000 CPUs drop the graphics slot to PCIe 4.0 x16 and the M.2_1 slot to PCIe 4.0 x4. This CPU-dependent lane allocation decides whether the board delivers peak bandwidth for your chosen processor.

Questions about this item

Will a Ryzen 9000 series CPU run the primary PCIe slot at full 5.0 x16 speed?

Yes. With a Ryzen 9000 or 7000 series processor the board provides one PCIe 5.0 x16 slot. Ryzen 8000 series CPUs limit that slot to PCIe 4.0 x8 or x4.

How many M.2 drives can I install and which one supports PCIe 5.0?

Three M.2 2280 slots are available. M.2_1 runs at PCIe 5.0 x4 with Ryzen 9000 or 7000 CPUs, while M.2_2 and M.2_3 operate at PCIe 4.0 x4.

Does the rear I/O include a 10 Gbps USB-C port for fast external storage?

The rear panel has one USB 10 Gbps Type-C port. A front-panel header for USB 5 Gbps Type-C is also present on the board.
