The ASUS ROG STRIX B850-I GAMING WIFI is a Mini-ITX AM5 motherboard for compact gaming PCs and small-form-factor builds using Ryzen 7000, 8000, or 9000 series processors, with DDR5, Wi-Fi 7, and two PCIe 5.0 M.2 slots.
Recommended For
- Builders fitting an AM5 gaming PC into a Mini-ITX case who want tested, solid gaming performance without moving to a larger motherboard.
- Small-form-factor builders who need two PCIe 5.0 M.2 slots—for example, to keep a fast OS or project drive alongside a separate high-speed game or media library.
- Compact-PC owners who prefer built-in Wi-Fi 7 and 2.5Gb Ethernet instead of using expansion slots for networking.
- Builders who want a compact AM5 system for CPU-heavy workloads as well as gaming; review testing found strong multithreaded results alongside solid gaming performance.
