ASUS ROG Strix B850-G Gaming WiFi
9.2/10★★★★★
The ASUS ROG Strix B850-G Gaming WiFi is the clearest overall winner in this micro-ATX pack when the goal is a compact AM5 gaming or AI-ready PC that does not feel compromised. It is ready for Ryzen 9000, 8000, and 7000 processors, pairs a robust 14+2+1 power solution rated for 80A per stage with 8+8-pin ProCool connectors, and stacks four M.2 slots—including a PCIe 5.0 M.2 plus additional PCIe 4.0 paths, one on the underside—for storage configurations that usually require ATX boards.

Power and thermals are built for multi-core Ryzen behavior. Massive heatsinks bridged to the VRMs with high-conductivity pads and an integrated I/O cover help when a micro-ATX case packs a hot GPU beside the socket.
Storage flexibility is the Strix’s killer feature versus every other board here. One PCIe 5.0 M.2 and multiple PCIe 4.0 M.2 slots with substantial heatsinks mean you can run OS, game library, and media drives without a SATA breakout nightmare.
Networking and USB are similarly ambitious. WiFi 7 (802.11be) is the forward play, with the important OS caveat from ASUS: full Wi-Fi 7 functions on Windows 11 want 24H2 or later; older Windows 11 builds may land on Wi-Fi 6E behavior, and Windows 10 support is more limited.
DIY features are where ROG earns its keep in cramped cases: PCIe Slot Q-Release, M.2 Q-Latch and Q-Release, Q-Antenna, Q-Dashboard, Q-LED, BIOS FlashBack, Clear CMOS, and a pre-mounted I/O shield. AI Advisor, AI Networking II, and AEMP aim to simplify tuning.
Who it is for
Enthusiasts building compact Ryzen 7000/9000 gaming PCs, creators who want four M.2 drives, and anyone prioritizing WiFi 7 plus ROG’s DIY conveniences in mATX.
OS and WiFi 7 notes
Update to a Windows 11 version that unlocks the board’s WiFi 7 feature set when possible. If you must stay on older Windows builds, treat wireless as WiFi 6/6E class until you upgrade the OS.
