Combo Ready for AM5 Builds

This bundle pairs a ROG Strix B850-G Gaming WiFi S motherboard with a Ryzen 7 9700X processor. The board uses the AMD B850 chipset and AM5 socket, supporting Ryzen 9000, 8000 and 7000 series CPUs. Four DIMM slots accept DDR5 up to 256 GB total capacity. It targets gamers and creators who want a white mATX platform with current-generation connectivity.

PCIe 5.0 and WIFI 7 Limits

The single PCIe 5.0 x16 slot provides high bandwidth for modern graphics cards and future expansion cards. Wireless networking uses WIFI 7 for low-latency gaming and fast transfers. USB 20Gbps Type-C is available for quick external storage. DDR5 memory runs at 5600 MT/s base speed, with overclocking headroom dependent on the CPU and memory kit.

White mATX Layout and Connectors

The white mATX form factor fits compact cases while exposing four M.2 slots for fast storage. A 40 MB cache on the processor aids gaming performance. Eight cores and sixteen threads deliver 100+ FPS in popular titles at a 5.5 GHz max boost clock. No cooler is included, so a separate AM5-compatible solution must be sourced.
