Does this board support Ryzen 5000 processors?

Yes. B550 with the AM4 socket supports Ryzen 5000 and 3000 series CPUs, though older 1000 and 2000 series chips are not supported. Check MSI's CPU support list for the exact model before buying.

How many M.2 drives can I install?

Two. One slot runs at PCIe 4.0 speed with a Ryzen 5000 or 3000 CPU, and the second slot is for additional storage. Both are M.2, so no 2.5-inch adapter is needed.

Do I need a Wi-Fi card with this motherboard?

No. Wi-Fi 6E and Bluetooth 5.3 are built in, so you only need to attach the included antennas. Wi-Fi 6E requires a compatible 6 GHz router to get its full speed.

Is there a USB-C port on the back panel?

No. The USB-C connection is a front-panel header for a case with a USB-C port. The rear I/O uses USB-A ports only.

What memory does it take?

It uses DDR4 DIMMs, rated up to 4400 MHz in MSI's specs. Higher speeds depend on the CPU's memory controller and the kit, so check the QVL for validated kits.

Is this board good for a small gaming build?

Yes, if you want a compact AM4 system with PCIe 4.0 graphics and a Gen4 SSD. It has fewer slots and no 2.5GbE, so step up to an ATX B550 or X570 board if you need more expansion.

Our take on the MSI PRO B550M-P WIFI6E AM4 AMD B550 Micro ATX Motherboard

The MSI PRO B550M-P WIFI6E is a micro ATX board for AMD's AM4 socket, built on the B550 chipset. It pairs PCIe 4.0 and a Gen4 M.2 slot with Wi-Fi 6E and Bluetooth 5.3, so you get fast storage and wireless without an add-in card. DDR4 memory support up to 4400 MHz, a second M.2 slot, front USB-C and Realtek 1GbE round it out. It suits builders who want a compact, well-connected AM4 board for Ryzen 5000 or 3000 chips and do not need the extra lanes of X570.
