Biostar B550MXC PRO AM4 microATX Motherboard

This motherboard uses the AMD B550 chipset and an AM4 socket to support Ryzen series processors. The microATX form factor fits smaller cases while providing four DDR4 memory slots for up to 128GB of system memory. A PCI Express 4.0 x16 slot handles modern graphics cards and a Gigabit RJ45 port provides wired networking.

Gamers building a compact Ryzen system

This board suits builders who want a compact platform for serious gaming with current Ryzen CPUs. It is not for users who need a full-size ATX layout with additional expansion slots or more than four memory slots. Buyers requiring integrated Wi-Fi or Bluetooth should verify availability as antennas are only included if applicable.

PCI Express 4.0 x16 graphics slot

The single PCI Express 4.0 x16 slot determines the graphics upgrade path and bandwidth for discrete GPUs. Four DDR4 slots define the maximum memory capacity of 128GB. The microATX size dictates case compatibility and the number of rear I/O ports available.
