AI Verdict
This is a Mini ITX LGA 1851 motherboard with Intel B860 chipset, DDR5 8933+ (OC) support, and PCIe 5.0 M.2 for compact Intel Core Ultra builds.
This motherboard is a strong contender for Mini ITX builds centered around Intel Core Ultra processors, offering cutting-edge features like PCIe 5.0 M.2 and WiFi 6E. However, its 'situational_fit' comes from the potential for WiFi troubleshooting, especially in SFF cases with riser cables, and the limited two DDR5 DIMM slots.
If you need more RAM capacity or a more robust audio solution, look for motherboards with four DIMM slots or an ALC1220 (or better) audio codec.

Pros
- Supports Intel Core Ultra Processors (Series 2) on LGA 1851 socket, ready for current-gen CPUs.
- Features a Blazing M.2 slot with PCIe Gen5x4, offering 128Gb/s transfer speeds for future-proof storage.
- Equipped with WiFi 6E (802.11axe) and Bluetooth for high-speed wireless connectivity.
- Includes Realtek 2.5G LAN and Intel Gigabit LAN for dual wired network options.
- Robust 8+1+1+1+1 Power Phase design with SPS for stable power delivery, even during overclocking.
- Supports DDR5 memory up to 8933+ MHz (OC) in dual channel mode.
Cons
- Limited to 2 DDR5 DIMM slots, restricting total RAM capacity to 128GB and upgrade flexibility.
- Uses Realtek ALC897 7.1 CH HD Audio Codec, which is a step down from the ALC1220 mentioned in some product descriptions.
- Only offers 1 HDMI and 1 DisplayPort for graphics output, which might be restrictive for multi-monitor setups without a discrete GPU.
- Some users have reported WiFi connectivity issues with the Intel AX211 adapter, potentially linked to PCIe riser cable settings in SFF cases.
Dimension Scores
The 8+1+1+1+1 Power Phase design with SPS and Hi-Density Power Connectors is above average for a Mini ITX board, supporting stable power for Intel Core Ultra CPUs and overclocking.
It includes WiFi 6E, Dual LAN (2.5G and Gigabit), Nahimic Audio, and a PCIe Gen5x4 M.2 slot, offering a strong set of modern features for its size.
While offering one PCIe 5.0 x16 slot, two M.2 slots, and four SATA3 ports, the limitation to only two DDR5 DIMMs is a common Mini ITX trade-off but restricts memory expansion.
No specific user feedback on BIOS or software was found, so it's scored as category average, assuming standard ASRock UEFI functionality.
Best For
- Small Form Factor (SFF) PC builds requiring an Intel Core Ultra CPU.
- Users prioritizing high-speed PCIe 5.0 M.2 storage in a compact system.
- Builders who need advanced wireless connectivity with WiFi 6E and Bluetooth.
- Enthusiasts looking to overclock DDR5 memory up to 8933+ MHz in a Mini ITX form factor.
Not Recommended For
- Users needing more than two DDR5 RAM sticks for higher memory capacity.
- Budget-conscious builders who don't require PCIe 5.0 or advanced power delivery.
- Anyone expecting a plug-and-play WiFi experience without potential troubleshooting in specific SFF configurations.
Watch Out For
- The Amazon rating of 4.4/5 from 71 reviews might be misleading due to potential ASIN hijacking, where reviews for a different product are displayed.
- WiFi connectivity issues with the Intel AX211 adapter have been reported, specifically when using PCIe riser cables set to Gen3 instead of Gen4/Auto, requiring manual BIOS adjustment.
- The audio codec is Realtek ALC897, not the higher-end ALC1220 as listed in some product descriptions, which might disappoint users expecting premium onboard audio.

What Buyers Say
While Amazon lists a 4.4/5 rating, there's a general concern about ASIN hijacking on the platform, which means those reviews might not be for this specific motherboard. However, specific user feedback on Reddit points to potential WiFi issues with the Intel AX211 adapter, which one user resolved by adjusting their PCIe riser cable setting from Gen3 to Gen4/Auto in the BIOS. This suggests that while the board offers advanced features, some users might need to troubleshoot specific configuration quirks, especially in compact builds.
“Man, this board is tiny but packs a punch with that Gen5 M.2, but seriously, my WiFi was acting up until I figured out my riser cable was messing with it, almost sent it back.”
Common Praise
- The inclusion of a PCIe Gen5x4 M.2 slot is a forward-looking feature for fast storage.
- Dual LAN (2.5G and Gigabit) provides flexible and fast wired networking options.
- WiFi 6E offers high-speed wireless connectivity.
- The 8+1+1+1+1 power phase design is considered robust for an ITX board.
Common Complaints
- WiFi connectivity problems with the Intel AX211 adapter, particularly when using PCIe riser cables set to Gen3.
- The audio codec is Realtek ALC897, not the higher-spec ALC1220 as some might expect or as initially listed in some product details.
- Only two DDR5 DIMM slots limit maximum RAM capacity and future upgrade paths.
Ownership Tips
- You might need to manually set your PCIe slot to Gen4 or Auto in the BIOS if you're using a riser cable and experiencing WiFi issues.
- The Realtek ALC897 audio codec is functional but don't expect top-tier audiophile performance from the onboard sound.
- Remember you only have two RAM slots, so plan your memory capacity carefully from the start.
- The dual LAN ports are a nice touch for network flexibility, especially if you have a 2.5G network at home.
