Overview
The MSI PRO B550M-P is a micro-ATX AM4 motherboard for Ryzen 5000, 5000G, 4000G, 3000 and 3000G series processors, built around the B550 chipset with DDR4 support.
It uses passive chipset cooling plus MSI's Frozr AI system, which adjusts fan speed automatically based on CPU and GPU temperature rather than a separate control app. The smaller mATX footprint trims connectivity versus the full ATX B550 boards in MSI's range, with a single Gigabit LAN port and no built in Wi-Fi. No customer reviews are attached to this listing yet.
- AM4 socket for Ryzen 5000 / 5000G / 4000G / 3000 series
- DDR4 memory overclocking up to 4400+ MT/s
- Dual M.2 slots, one Gen4 and one Gen3
- Frozr AI automatic fan control
Who it's for
Builders assembling a compact AM4 system with a Ryzen 5000 series or older chip who don't need onboard Wi-Fi or multiple expansion slots. Not the right fit for anyone wanting Wi-Fi built in or planning a build with more than one PCIe x16 card.

Performance notes
MSI's Core Boost VRM design targets stable power delivery for Ryzen 5000 series chips on the B550 chipset, with passive chipset heatsinks and the Frozr AI system automatically adjusting case fan speeds off CPU and GPU temperature readings. Four DDR4 slots support overclocking up to 4400+ MT/s, and the single PCIe 4.0 x16 slot with steel armor carries the graphics card. Storage covers an M.2 Gen4 x4 slot and a second M.2 Gen3 x4 slot, with a Gigabit LAN port and 7.1 HD audio on the rear panel.
