Overview

The ASUS ROG Strix B850-I Gaming WiFi is a premium Mini-ITX motherboard engineered for AMD AM5 processors, delivering exceptional performance in a compact form factor. Whether you're building a high-end small form factor (SFF) gaming rig or a powerful workstation, this board combines cutting-edge features with the reliability and style ROG is known for.

Unleash AMD Ryzen Performance

Built on the AMD B650E chipset, the B850-I supports Ryzen 7000, 8000, and 9000 series CPUs. Its robust VRM design with dedicated heatsinks ensures stable power delivery even under heavy loads, allowing you to overclock your processor with confidence. The board supports PCIe 5.0 for both graphics and storage, providing blazing-fast data transfer speeds for the latest GPUs and SSDs.

Next-Gen Memory and Storage

With two DDR5 DIMM slots, the motherboard supports up to 128GB of RAM and speeds up to 8400+ MHz (OC) via AMD EXPO technology. For storage, you get two M.2 slots—one PCIe 5.0 x4 and one PCIe 4.0 x4—both equipped with dedicated heatsinks to keep your NVMe SSDs cool. Additionally, two SATA 6 Gb/s ports offer traditional storage options.

Connectivity and Networking

Stay connected with Intel 2.5 Gb Ethernet and Wi-Fi 6E (802.11ax) with Bluetooth 5.2. The rear I/O panel includes a USB 3.2 Gen 2x2 Type-C port, multiple USB 3.2 and USB 2.0 ports, DisplayPort and HDMI outputs (for CPUs with integrated graphics), and a BIOS FlashBack button for easy firmware updates. Front-panel USB headers include a Gen 2 Type-C connector, a Gen 1 header, and a USB 2.0 header.

Designed for SFF Enthusiasts

The Mini-ITX form factor (17cm x 17cm) fits perfectly in compact cases, making it ideal for portable gaming setups or minimalist workstations. The board's layout is optimized for airflow and component clearance, ensuring easy installation and clean cable management. ROG-exclusive software like AI Suite and Armoury Crate provides intuitive control over system tuning and RGB lighting.

Who Is It For?

This motherboard is perfect for gamers and creators who demand top-tier performance in a small footprint. If you're building a powerful SFF PC with an AMD Ryzen 9000 series CPU and a high-end graphics card, the B850-I offers the features and reliability you need.
