Compact AM5 platform

This bundle pairs the ROG Strix B850-I Gaming WiFi motherboard with the Ryzen 9 9900X processor for a Mini-ITX build. The board uses the AMD B850 chipset and an AM5 socket that supports Ryzen 9000, 8000 and 7000 series CPUs. Two DDR5 slots accept up to 96 GB of memory in dual-channel mode with ECC support. It targets enthusiasts who need high core counts in a small chassis.

Sustained 70 A power delivery

The 10+2+1 stage VRM is rated for up to 70 A per stage and uses ProCool power connectors to handle continuous current. Massive heatsinks with an integrated I/O cover and high-conductivity thermal pads dissipate heat during long workloads. AI Overclocking and AI Networking II adapt voltages and traffic in real time to keep performance stable. AEMP and EXPO profiles simplify memory tuning for extended sessions.

12-core Zen 5 CPU included

The Ryzen 9 9900X brings 12 cores and 24 threads based on the Zen 5 architecture with a 5.6 GHz maximum boost clock and 64 MB of cache. It is unlocked for overclocking and plugs directly into the AM5 socket. This processor determines the compute ceiling for rendering, compilation and multi-tasking workloads. The combination delivers a complete high-performance foundation in a compact form factor.
