Overview

A Micro-ATX motherboard built on the AMD B840 chipset for Socket AM5 processors. It supports DDR5 memory up to 8200 MT/s and offers dual M.2 slots, 2.5 GbE LAN, and EZ-Latch installation aids.

Platform and Power Delivery

The board uses the AMD B840 chipset on a Micro-ATX form factor for Socket AM5. An 8+2+2 phase VRM supplies stable power to Ryzen 7000 and 9000 series processors through a single 8-pin CPU connector.

Memory and Storage

Four DDR5 DIMM slots accept up to 256 GB with standard speeds of 5200 MT/s and overclocked speeds up to 8200 MT/s. Storage includes two PCIe 4.0 x4 M.2 slots and four SATA 6Gbps connectors.

Connectivity and Rear I/O

Rear I/O provides HDMI 2.1, two DisplayPort outputs, one USB-C 3.0, two USB-A 3.0, four USB-A 2.0, and a single 2.5 GbE LAN port. Internal headers add one USB-C 3.0, one USB-A 3.0, two USB 2.0, and front-panel audio.

Expansion and Installation Features

Two PCIe x16 slots (one PCIe 4.0 x1 mechanical, one PCIe 3.0 x1 mechanical) handle graphics and add-in cards. EZ-Latch simplifies GPU removal, while Q-Flash Plus enables BIOS updates without an installed CPU.
