AM5 platform with B650 chipset

This micro-ATX motherboard uses the AMD B650 chipset and Socket AM5 to support Ryzen 7000 and 8000 series desktop processors. It provides a compact foundation for a new build or an upgrade to the current AM5 generation.

DDR5 memory and 2.5 GbE LAN

The four DIMM slots accept DDR5 up to 256 GB with JEDEC 4800 MHz and a wide range of overclocked speeds up to 7200 MHz. Rear I/O includes 2.5 GbE LAN, 10 Gbps USB Type-A and Type-C ports plus 7.1-channel audio from the Realtek ALC897 codec.

PCIe lane allocation depends on CPU

The single PCIe x16 slot runs at x16 with Ryzen 7000 CPUs, drops to x8 for Ryzen 7 8700G and Ryzen 5 8600G, and runs at x4 for Ryzen 5 8500G. Two additional PCIe x1 slots and two M.2 interfaces are available regardless of processor choice.

Questions about this item

What case clearance does the 23.6x20.0cm Micro-ATX board need for the I/O shield and front-panel headers?

The board measures 23.6 by 20.0 cm, so any case with a standard Micro-ATX cut-out and front-panel header reach will fit. Align the included I/O shield before securing the nine mounting screws.

Which DDR5 DIMM slots should I populate first for a dual-channel kit on this four-slot board?

Install the first kit in the two slots furthest from the CPU socket — usually labelled DDR5_1 and DDR5_2 — to enable dual-channel operation.

How long does the onboard Realtek ALC897 audio codec typically last before sound quality drops?

The Realtek ALC897 7.1-channel codec is a solid-state component with no moving parts; it does not wear out under normal use and rarely requires replacement.
