MSI MAG B550M BAZOOKA AMD Motherboard A

Core platform

This motherboard uses the AMD B550 chipset and AM4 socket in a MicroATX form factor. It accepts DDR4 memory up to 128 GB across its slots. One PCI Express 3.0 x16 slot and a single PCI slot handle expansion cards. Rear I/O provides DisplayPort, a USB 3.1 Gen 2 Type-A port and one RJ45 LAN connection.

Build fit

The board suits builders assembling a compact AM4 system with standard DDR4 memory and a single graphics card. Two M.2 slots allow fast solid-state storage without extra cables. Buyers who need more than one x16 slot or additional rear USB ports should look at a larger form factor.

Deciding spec

The AM4 socket and B550 chipset define which processors and chipset features are available. Match the CPU to this socket before purchase. The single PCI Express 3.0 x16 lane layout also sets the ceiling for graphics performance.
