ASUS ROG Strix X870-I Gaming WiFi

The premium AM5 ITX option in the pro tier, this X870 board packs WiFi 7, USB4, Gen5 M.2, and 10+2+1 power stages into a mini-ITX footprint. It's built for SFF enthusiasts who refuse to compromise on connectivity. The limits are inherent to the form factor — two DIMM slots, two M.2, a single PCIe slot — so multi-drive or expansion-heavy builders should step up to ATX.

Compatibility

Built around AMD AM5, DDR5, Mini-ITX, PCIe 5.0. Make sure the rest of your build uses the same platform before you buy — mismatched sockets, mounts or standards are the most common return reason. Check it in the builder →

Upgrade path

Buying today, the MSI MAG X870 Tomahawk WiFi scores higher for less — the smarter pick in motherboards unless you specifically want this one. See it →
