Overview

An ATX motherboard built on the Intel B860 chipset for LGA 1851 processors. It supports DDR5 memory up to 8600 MT/s and includes Wi-Fi 7 plus Thunderbolt 4.

Layout and Cooling

The board uses a black and silver ATX layout measuring 304.8 mm 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.

Memory and Expansion

Four DIMM slots accept up to 256 GB of DDR5 CUDIMM or UDIMM modules. The primary PCIe 5.0 x16 slot runs at x16, while a second x16 slot operates at x4 and two more run at x1, all on PCIe 4.0.

Storage and Connectivity

Three M.2 sockets provide one PCIe 5.0 x4 and two PCIe 4.0 x4 connections alongside four SATA 6 Gbps ports. External I/O includes Thunderbolt 4, two USB 3.1, two USB 3.0, four USB 2.0, HDMI, USB-C DisplayPort, and 5 GbE LAN.

Wireless and Audio

Integrated Wi-Fi 7 and Bluetooth 5.4 handle wireless duties. The Realtek ALC897 codec drives onboard audio, and RGB lighting is supported through one 12 V header and two 5 V/12 V digital headers.
