Overview

An ATX motherboard built on the Intel B860 chipset for LGA 1851 processors. It targets gamers and builders who want PCIe 5.0 and fast DDR5 without CPU overclocking.

Design and Cooling

The board uses a black ATX layout measuring 304.8 by 243.8 mm. It includes VRM heatsinks, M.2 shields, a rear I/O backplate, and six 4-pin PWM headers for fans or radiators. RGB and digital RGB headers are provided for lighting control.

Performance and Memory

Supports Intel Arrow Lake processors with a 4-pin plus 8-pin CPU power configuration. Four UDIMM slots accept up to 256 GB of DDR5. Standard speed is 6400 MT/s with overclocked support to 8600 MT/s via Intel XMP 3.0 profiles.

Storage and Expansion

Three M.2 slots include one PCIe 5.0 x4 and two PCIe 4.0 (x4 and x2). Four SATA 6 Gbps ports are available. Expansion consists of one PCIe 5.0 x16 slot, one PCIe 4.0 x16 slot running at x4, and two PCIe 4.0 x1 slots.

Connectivity

External I/O offers one Thunderbolt 4 USB4 port, two USB 3.1 Type-A, two USB 3.0 Type-A, and four USB 2.0 Type-A ports. Video outputs include HDMI, DisplayPort, and a USB-C DisplayPort alt mode. Networking uses an Intel Killer E5000 5 GbE controller and a Killer BE1750x Wi-Fi 7 with Bluetooth 5.4 module.
