Socket AM4 Mini-ITX platform

The MSI MPG B550I Gaming Edge WiFi is a Mini-ITX motherboard built around the AMD B550 chipset and Socket AM4. It supports 3rd Gen AMD Ryzen processors and future Ryzen CPUs with a BIOS update. Dual-channel DDR4 memory runs at speeds from 1866 up to 4600+ MHz with a 64 GB maximum capacity.

Compact builders and high-speed memory users

This board suits builders assembling a small-form-factor system who need 2.5 Gbps LAN, 7.1-channel audio and two M.2 slots alongside four SATA III ports. It is not suited for anyone requiring a larger ATX layout, more than one full-length PCIe slot or memory capacity beyond 64 GB.

Single PCIe 4.0 x16 slot

The board provides only one PCIe 4.0/3.0 x16 expansion slot. If your build demands a second graphics card, a capture card or additional expansion cards, this motherboard cannot accommodate them.

Questions about this item

What comes in the box and what must I buy separately?

The package includes the motherboard, a CMOS battery, one SATA cable, the rear I/O shield and the Wi-Fi antenna. You still need to buy a Socket AM4 Ryzen processor, DDR4 memory modules, storage drives and a power supply.

Which memory speed should I choose for this board?

The board supports dual-channel DDR4 from 1866 MHz up to 4600 MHz and a maximum of 64 GB. Pick a kit that matches your CPU's memory controller and your budget; any speed in that range will work.

What does the 2.5 Gbps LAN figure mean in daily use?

The Realtek RTL8125B controller provides a 2.5 Gbps wired link, so large file transfers and low-latency gaming see higher throughput than standard 1 Gbps Ethernet when your router and cabling also support 2.5 Gbps.
