Product details

The ASROCK B850M Pro RS is a Micro-ATX mainboard with the mid-range AMD B850 chipset and AMD AM5 socket. It supports both the Ryzen 9000, 8000 and 7000 CPUs.

Graphics cards and NVMe SSDs are connected via PCIe 5.0 and data transfer rates of up to 10 Gbit/s are possible via USB 3.1.

To get the best out of your gaming PC, the CPU can be overclocked to higher clock rates via the mainboard. This ensures a stable power supply to the processor so that even high-end CPUs can operate at full power over a longer period of time. You can also fully utilise the DDR5 memory with overclocking. Just in case, the ASROCK B850M Pro RS offers you BIOS flashback.
