Does it support Ryzen 5000 out of the box?

Most units ship with a BIOS new enough for Ryzen 5000, but older stock may need a BIOS update first. Check the board revision before buying if you have no older AM4 CPU to boot with.

Can I use two PCIe 4.0 M.2 drives?

No. Only the first M.2 slot runs PCIe 4.0, and only with a Ryzen 5000 or 3000 CPU. The second slot runs at PCIe 3.0.

Do I need a graphics card?

Only if your CPU lacks integrated graphics. With a Ryzen G-series APU the HDMI, DisplayPort and VGA outputs drive a display directly.

No. Networking is Realtek 1GbE Ethernet only, so add a Wi-Fi card or USB adapter if you need wireless.

What comes in the box?

The board, I/O shield, SATA cables, M.2 screws and a quick guide. Check the listing for the exact bundle.

Is it good for overclocking?

It handles light memory and CPU tuning, but the modest VRM cooling makes it a poor fit for pushing high-core chips hard.

Our take on the MSI PRO B550M-P AMD AM4 Micro-ATX Motherboard

The MSI PRO B550M-P is a micro-ATX AM4 board built on AMD's B550 chipset for Ryzen 3000, 4000G and 5000 processors. It covers the basics for a compact build: two M.2 slots, PCIe 4.0 from the CPU, DDR4 rated to 4400+ MHz, USB 5Gbps Type-C and Realtek 1GbE LAN. Its three video outputs (HDMI, DisplayPort, VGA) make it a practical pick for office and home PCs with a Ryzen APU. Against pricier B550M boards it gives up Wi-Fi, a second full-speed PCIe 4.0 slot and heavier power delivery, so it suits budget builds rather than overclocking or high-core CPUs under sustained load.

What reviewers say

Owners of budget AM4 builds generally find the board does what it promises: stable with Ryzen 5000 chips, easy to set up and well laid out for a micro-ATX case. Complaints center on the light VRM heatsinks and the lack of wireless.

What people mention

VRM thermalsMixedFine with mid-range Ryzen chips, but warm under sustained load with high-core models.
WirelessCriticisedNo Wi-Fi or Bluetooth, so buyers add a card or dongle.
M.2 slotsPraisedTwo slots are handy, though only the first runs PCIe 4.0.
BIOS and setupPraisedOwners describe the BIOS as straightforward and the layout as easy to build in.
Fan headersCriticisedFewer headers than some rivals, which limits fan-heavy builds.
