Overview

A Mini-ITX motherboard built on the AMD B850 chipset for Socket AM5 processors. It fits compact cases while delivering PCIe 5.0 graphics and storage support, DDR5 memory overclocking, and Wi-Fi 7 connectivity.

Compact AM5 Platform

The Mini-ITX form factor measures 170 mm square and uses the AMD B850 chipset with Socket AM5. It accepts Ryzen 9000, 8000, and 7000 series processors and includes a pre-installed I/O shield for easier installation.

Memory and Expansion

Two UDIMM slots support up to 96 GB of DDR5 with AMD EXPO profiles up to 8400 MT/s. A full-length PCIe 5.0 x16 slot handles modern graphics cards, while one PCIe 5.0 and one PCIe 4.0 M.2 slot provide high-speed storage options alongside two SATA 6G ports.

Connectivity and Networking

External ports include one USB-C 3.2 Gen 2x2 (20 Gbps), one USB-C 3.1, four USB-A 3.1, two USB-A 2.0, HDMI, and 2.5 Gbps Ethernet. Wireless connectivity uses Wi-Fi 7 and Bluetooth 5.4. Internal headers add one USB-C 3.2, one USB-A 3.1, one USB-A 2.0, two addressable RGB headers, and front-panel audio.

Power and Cooling Features

An 8-pin CPU power connector feeds robust VRM cooling with dedicated heatsinks. Both M.2 slots have heatsinks, and a rear backplate adds structural rigidity. Four 4-pin PWM fan headers allow precise cooling control for compact builds.
