  • 4K 60 Hz video output through HDMI 2.1 and DisplayPort 1.4

Ready for demanding multi-threaded workloads

This bundle pairs the MSI PRO B850M-P WIFI motherboard with the AMD Ryzen 9 9950X processor. The CPU delivers 16 cores and 32 threads on the Zen 5 architecture with a 5.7 GHz maximum boost frequency. The Micro-ATX board uses the AMD B850 chipset and AM5 socket, supporting Ryzen 7000, 8000 and 9000 series processors. It targets content creators and professionals who need high core counts in a compact form factor.

Step up from an older AM5 platform

The combination replaces a system built around a Ryzen 7000 or 8000 series CPU on a B850 board when the workload demands the 9950X’s 64 MB L3 cache and higher boost clocks. The motherboard adds PCIe 5.0 for the primary graphics slot, four SATA 6Gb/s ports, Realtek 8126 5G LAN, Wi-Fi 7 and Bluetooth 5.4. Dual-channel DDR5 runs up to 8200 MT/s over four slots with a 256 GB maximum capacity. The jump is worthwhile when rendering, compilation or simulation times are limited by core count and memory bandwidth.

Suits compact workstations, not extreme overclocking

The bundle fits builders who want a 16-core workstation in a smaller chassis with modern connectivity including HDMI 2.1, DisplayPort 1.4, USB 10Gbps Type-A and Type-C, and 5G wired networking. Users chasing maximum memory overclocking headroom or extensive multi-GPU configurations should look at full-size ATX boards with enhanced power delivery and additional PCIe 5.0 slots. A CPU cooler is not included and must be sourced separately.

Questions about this item

Will the Ryzen 9 9950X fit in this motherboard without a BIOS update?

The board uses the AM5 socket and B850 chipset, which are built for Ryzen 7000, 8000 and 9000 series processors, so the 9950X is supported out of the box.

What memory speed can I run with the included CPU and this board?

The motherboard supports DDR5 up to 8200 MT/s when overclocked, while the 9950X officially supports DDR5-5600; both will work together at the lower rated speed and can be tuned higher in BIOS.

Do I need a separate graphics card to get a display signal?

The 9950X includes integrated graphics, and the board provides HDMI and DisplayPort outputs, so a discrete GPU is not required for 4K 60 Hz output.
