AM5 Micro-ATX for Ryzen 7000 and 9000

This ASRock B650M Pro RS motherboard fits the AM5 socket and supports AMD Ryzen 7000 Series and Ryzen 9000 Series processors. It uses the AMD B650 chipset on a compact Micro-ATX layout. A BIOS update may be required before installing a 9000 Series CPU. The board delivers an 8+2+1 Dr.MOS power phase design for stable operation.

Suits compact DDR5 builds, not multi-GPU

The board suits builders who want a small-form-factor system with up to 128 GB of dual-channel DDR5 across four slots. Memory runs at DDR5 6000+ (OC) and supports both AMD EXPO and Intel XMP 3.0 profiles. Only one PCIe 4.0 x16 slot is wired for graphics, so multi-GPU configurations are not an option. The second x16 slot runs at PCIe 3.0 x4 electrically.

PCIe Gen5 M.2 and 5 GbE ceiling

The primary M.2 socket (M2_1) connects directly to the CPU and runs at PCIe Gen5 x4, providing 128 Gb/s bandwidth for the fastest NVMe drives. Two additional M.2 sockets operate at PCIe Gen4 x4 and Gen4 x2 respectively. Wired networking tops out at 5 GbE via the Realtek Dragon RTL8125BG controller.
