ASUS ROG STRIX B860-I GAMING WIFI Mini-ITX Motherboard - Future-Ready

In this review the ASUS ROG STRIX B860-I GAMING WIFI is evaluated as a compact, high-performance Mini-ITX motherboard aimed at builders who want next-generation CPU and AI readiness in a small build. The bottom line: this board is for enthusiasts who need Intel LGA 1851 support for Intel Core Ultra Series 2, DDR5 memory, and modern connectivity like WiFi 7 and Thunderbolt 4, all packed into a Mini-ITX footprint. Its combination of a robust power delivery design and specialized ASUS AI and memory tools makes it the strongest choice for small-form-factor AI-capable or gaming systems.

Key Features

• Intel LGA 1851 Socket: Ready for Intel Core Ultra Series 2 processors so builders can use the latest high-performance CPUs without a platform change.
• Advanced AI readiness: ASUS AI Advisor and AI Networking II provide simplified tuning and network prioritization for AI workloads and low-latency applications.
• Robust power solution: A 10+1+2+1 stage design with 80A power stages and ProCool connectors offers stable delivery under heavy CPU loads and overclocking.
• High-speed connectivity: Includes WiFi 7 and 2.5G LAN plus Thunderbolt 4 and USB Type-C for fast networking and peripheral throughput in a compact board.
• Thermal optimization: Massive heatsinks, integrated I/O cover and an L-shaped heatpipe with high-conductivity pads help keep VRMs and storage cool in cramped cases.
• Storage and expansion: Dual M.2 support and a PCIe 5.0 x16 SafeSlot make room for next-gen NVMe storage and full-size GPUs in a Mini-ITX build.

Who It's For

The ASUS ROG STRIX B860-I is best for small-form-factor builders who want to run an Intel Core Ultra Series 2 CPU, use DDR5 memory, and need modern I/O such as Thunderbolt 4 and WiFi 7 while keeping the system compact. It suits gamers who plan to pair a powerful GPU or creators who need fast NVMe storage and advanced AI/network tuning in a Mini-ITX chassis.

Those who should look elsewhere include buyers on a strict budget who do not need cutting-edge connectivity or AI features, and users who require plentiful legacy expansion slots beyond what a Mini-ITX board can provide. If WiFi compatibility with a specific setup is critical, verify wireless behavior first since some customers reported issues in certain environments.

Pros & Cons

Pros

• Comprehensive modern I/O including Thunderbolt 4, USB Type-C, WiFi 7 and 2.5G LAN for versatile connectivity.
• Strong power delivery with multiple 80A stages and ProCool connectors for stable performance under heavy loads.
• Dual M.2 and PCIe 5.0 x16 SafeSlot allow fast storage and next-gen GPU compatibility in a Mini-ITX layout.
• ASUS-exclusive tools like AI Advisor and AI Networking II help optimize performance and networking for advanced workloads.

Cons

• Mini-ITX size limits expansion and may cause tighter thermal constraints in some cases despite the board's heatsinks.
• Some users reported mixed experiences with WiFi compatibility, so wireless performance can vary by environment or client hardware.
