ASUS TUF Gaming B850I WiFi NEO Mini-ITX AM5 Motherboard
The ASUS TUF Gaming B850I WiFi NEO Mini-ITX AM5 Motherboard brings TUF Gaming performance to the Mini-ITX form factor for the first time, making it suited to builders who want a compact but capable platform for AMD Ryzen processors and demanding AI PC applications. It pairs PCIe 5.0 storage, WiFi 6E, and a robust multi-phase power solution in a 6.7 × 6.7 inch footprint, addressing the need for full-featured performance in small form-factor builds.
Why this product
Mini-ITX with full PCIe 5.0 support
A PCIe 5.0 x16 slot and a PCIe 5.0 x4 M.2 slot (with Ryzen 9000/7000) deliver the latest storage and graphics bandwidth in a compact 6.7 × 6.7 inch board.
Robust 10-layer server-grade PCB
The 10-layer PCB uses 2-ounce low-loss copper power planes for enhanced signal integrity and stable power delivery, backed by military-grade components.
WiFi 6E and 2.5Gb Ethernet onboard
Wi-Fi 6E 2×2 with 160 MHz bandwidth across 2.4 GHz, 5 GHz, and 6 GHz bands is complemented by Realtek 2.5Gb Ethernet for fast wired connections.
DDR5 up to 9600 MT/s (OC)
Two DIMM slots support up to 128 GB of DDR5 with AMD EXPO and ASUS AEMP profiles, reaching up to 9600 MT/s (OC) with Ryzen 8000 Series processors.
Abundant USB connectivity
Six rear USB ports include a USB 20Gbps Type-C port, plus five front USB connectors, so high-speed peripherals and storage devices are well catered for.
DIY-friendly tools built in
Q-Antenna, Q-Dashboard, Q-LED, a Clear CMOS button, and BIOS FlashBack make initial setup and troubleshooting straightforward without needing a running system.

- EAN4711636580915
- Supports AMD Ryzen 9000, 8000, and 7000 Series Desktop Processors via the AM5 socket.
- Fits standard Mini-ITX cases; the board measures 6.7 × 6.7 inches (17 × 17 cm).
- Accepts DDR5 ECC and Non-ECC Un-buffered DIMMs in dual-channel configuration up to 128 GB across two slots.
- Officially supports Windows 11 as the listed operating system.
- PCIe 5.0 x16 and PCIe 5.0 x4 M.2 speeds apply to Ryzen 9000 and 7000 Series; Ryzen 8000 Series is limited to PCIe 4.0 x16 and PCIe 4.0 x4 on those same slots.
- DisplayPort 1.4 and HDMI 2.1 outputs on the rear panel are functional only when using a Ryzen processor with integrated graphics; a discrete GPU is required otherwise.
Best for
- Compact gaming or AI PC builds where Mini-ITX dimensions are required but PCIe 5.0 and WiFi 6E performance cannot be compromised.
- AMD Ryzen 9000 and 7000 builders who want PCIe 5.0 storage on the primary M.2 slot alongside a second PCIe 4.0 M.2 slot.
- Connectivity-focused users who need a USB 20Gbps Type-C port on the rear panel plus multiple high-speed front-panel headers in a small board.
- Wireless-first setups that benefit from Wi-Fi 6E 160 MHz bandwidth across three frequency bands plus Bluetooth with LE Audio support.
- Self-builders who value diagnostic tools such as BIOS FlashBack, Clear CMOS, and Q-LED for easier troubleshooting without a fully assembled system.
Trade-offs
- Builds requiring more than two memory slots — the board provides only two DIMM slots, limiting memory configuration flexibility.
- Multi-GPU or multi-PCIe card setups — only one PCIe x16 slot is present on this Mini-ITX board.
- Ryzen 8000 Series users seeking PCIe 5.0 — those processors are limited to PCIe 4.0 x16 on the expansion slot and PCIe 4.0 x4 on the primary M.2 slot.
- Builds needing more than two SATA ports — only two SATA 6Gb/s ports are available alongside the two M.2 slots.
- Linux-primary users — the listed operating system support is Windows 11 only.
