Overview

A Micro-ATX motherboard built on the AMD B850 chipset for Socket AM5 processors. It supports Ryzen 7000, 8000, and 9000 series CPUs with DDR5 memory up to 8200 MT/s.

Design and Power Delivery

The board uses a Micro-ATX form factor with a black PCB. It includes an 8-pin CPU power connector and VRM heatsinks to sustain high-end processor loads. Two M.2 heatsinks cover both storage slots.

Memory and Expansion

Two DDR5 DIMM slots accept up to 128 GB with AMD EXPO and Intel XMP profiles. Expansion includes one PCIe 4.0 x16 slot, a second x16 slot wired at x4, and one x1 slot. Storage offers one PCIe 5.0 M.2, one PCIe 4.0 M.2, and four SATA 6G ports.

Connectivity and I/O

Rear I/O provides one USB-C 3.0, three USB-A 3.0, two USB-A 2.0, HDMI, DisplayPort, and a 2.5 GbE LAN port. Wireless uses Wi-Fi 6E and Bluetooth 5.2. Internal headers add one USB-C 3.0, two USB-A 3.0, four USB 2.0, front audio, and SPI TPM.

Cooling and Features

Six 4-pin PWM fan headers support chassis and radiator fans. The Realtek ALC897 codec handles audio. BIOS Flashback allows firmware updates without a CPU installed. RGB lighting headers are present for customization.
