Dimension Scores
The 10+1+2+1 power stages, each rated for 80A, with ProCool connectors and premium components, provide robust power delivery for high-performance CPUs.
It includes WiFi 7, 2.5G LAN, Thunderbolt 4, PCIe 5.0 M.2, and ASUS AI technologies, offering a comprehensive set of modern features for a Mini-ITX board.
As a Mini-ITX board, it offers expected limitations with one PCIe 5.0 x16 slot and two M.2 slots, which is average for its form factor.
The BIOS offers features like NPU Boost and Asynchronous Clock for fine-tuning, but user feedback suggests ASUS software utilities could be improved.
Best For
- Building a compact, high-performance Mini-ITX gaming PC with Intel Core Ultra Series 2 processors.
- Users requiring advanced AI computing capabilities in a small form factor.
- Systems needing cutting-edge connectivity with WiFi 7, 2.5G LAN, and Thunderbolt 4.
- Enthusiasts aiming for high-speed DDR5 memory configurations up to 8000 MHz.
Not Recommended For
- Users planning to overclock their Intel Core Ultra Series 2 CPU.
- Builds requiring more than two DDR5 memory modules or extensive PCIe expansion slots.
Watch Out For
- The B860 chipset prevents CPU overclocking, meaning you won't be able to push an unlocked processor beyond its stock speeds.
- Only two DDR5 DIMM slots are available, limiting maximum RAM capacity to 96GB.
- The included antenna is essential for Bluetooth functionality; without it, Bluetooth will not work properly.
- ASUS's software utilities, like Armoury Crate, have been reported to lack functionality and have a less intuitive user interface compared to older versions.

What Buyers Say
While the motherboard delivers on its promise of robust hardware for compact builds, the software experience could be smoother. Users appreciate the board's quality and audio components, noting its suitability for a no-fuss build. However, the included manual is less detailed than previous generations, and the ASUS software utilities have room for improvement in terms of functionality and user interface. The lack of CPU overclocking support is a key limitation to consider for performance enthusiasts.
“Look, this thing is built like a tank for a tiny board, and the sound is actually good, but seriously, ASUS, fix your software and give us a real manual!”
Common Praise
- The layout is well-designed, making for a straightforward build process.
- The audio quality stands out, with dedicated layers and high-quality components supporting 7.1 channel systems.
- The board appears to be of solid quality, as expected from ASUS.
- Offers a comprehensive set of features for a compact, micro-ATX build.
Common Complaints
- The B860 chipset does not allow for CPU overclocking, even with unlocked processors.
- ASUS software utilities, including Armoury Crate, could use more functionality and a better user interface.
- The printed manual included with the motherboard is very limited compared to what was previously provided.
- Bluetooth functionality requires the included antenna to be attached for proper operation.
Ownership Tips
- The compact size means careful cable management is crucial for airflow and aesthetics.
- Updating BIOS and drivers through ASUS DriverHub is easier, but the overall utility suite feels less refined than older versions.
- The thermal design with massive heatsinks helps keep temperatures in check even in cramped Mini-ITX cases.
- The pre-mounted I/O shield simplifies installation, which is a small but appreciated detail for Mini-ITX builds.

Buying Guide
When you're looking at a motherboard, especially a Mini-ITX one, you need to think about what you're actually going to put in your PC. This board is for Intel's new Core Ultra Series 2 chips, so make sure your CPU matches. Since it's small, expansion slots are limited, so plan your storage and graphics card carefully. The B860 chipset means no CPU overclocking, so if you want to push your chip to its limits, this isn't the one. Connectivity is key for a modern build, and this board packs a lot into its small size.
LGA 1851 Socket
This is the physical connection point for your CPU. It dictates which generation of Intel processors you can use. LGA 1851 is for Intel Core Ultra Series 2, so older or newer CPUs won't fit.
DDR5 RAM
This refers to the type of memory (RAM) the board supports. DDR5 is the latest standard, offering faster speeds than DDR4. Think of it like a wider, faster highway for your computer's short-term memory.
Mini-ITX Form Factor
This is the physical size of the motherboard. Mini-ITX boards are the smallest standard, perfect for compact PC builds where space is at a premium. The trade-off is fewer expansion slots and RAM slots compared to larger boards.
10+1+2+1 Power Stages
This describes the power delivery system for your CPU. More stages with higher amperage (like 80A here) mean more stable and efficient power, especially important for demanding processors and system stability.
Alternatives
If you need CPU overclocking, search for LGA 1851 motherboards with a Z-series chipset. For more PCIe slots or additional RAM slots, consider larger form factors like Micro-ATX or ATX.
