ASRock B550M-P

A budget AM4 Micro ATX board with PCIe 4.0 graphics and M.2, 2.5 Gigabit LAN and HDMI + DisplayPort for Ryzen 3000/5000 and G-series APUs.
AMD B550 · AM4PCIe 4.0 x16 + Gen4 M.22.5GbE LANHDMI 2.1 + DP 1.4

The ASRock B550M-P (part number 90-MXBV10-A0UAYZ) is an AMD B550 Micro ATX motherboard for Socket AM4 Ryzen 3000, 4000 G-Series, 5000 and 5000 G-Series desktop processors. It is a cost-effective way to build or refresh a DDR4 PC: a PCIe 4.0 x16 slot and a Gen4 x4 M.2 socket come from the CPU, four SATA ports cover existing drives, and a Realtek Dragon 2.5GbE port replaces the usual Gigabit LAN. HDMI 2.1 and DisplayPort 1.4 outputs serve Ryzen APUs with integrated Radeon graphics.

Compatibility Note: This is an AM4 / DDR4 board: it does not accept AM5 Ryzen 7000/8000/9000 CPUs or DDR5 memory. PCIe 4.0 on the x16 slot and M.2 requires a Ryzen 5000 or 3000 CPU; Ryzen 4000G/5000G APUs run at PCIe 3.0. The 12V CPU input is a single 4-pin connector, and NVMe is not supported with the Athlon 3000G.
Best For
✓ Budget AM4 gaming PCs
✓ Ryzen 5 5600 / 5700X builds
✓ Ryzen 5600G / 5700G office PCs
✓ Reusing existing DDR4 memory
✓ 2.5GbE home networks
✓ Small Micro ATX cases

Key Features

 
PCIe 4.0 from the CPU
With a Ryzen 5000 or 3000 processor, the x16 slot and the Hyper M.2 socket (2260/2280, SATA or PCIe Gen4 x4 at 64 Gb/s) run at PCIe 4.0 speeds.
 
2.5 Gigabit LAN
Realtek Dragon RTL8125BG 2.5GbE with Dragon software for traffic prioritisation — faster transfers to a 2.5GbE NAS or switch than standard Gigabit.
 
Display Outputs for APUs
HDMI 2.1 (4K 60Hz) and DisplayPort 1.4 (up to 5K 120Hz) for Ryzen G-series APUs with Radeon Vega graphics, useful for dual-monitor office PCs.
 
Useful Headers
Front USB 3.2 Gen1 Type-C header, COM port and SPI TPM headers, 1x RGB + 3x ARGB headers, plus a rear USB 3.2 Gen1 Type-C port.

Frequently Asked Questions

Which Ryzen CPUs work with the B550M-P?
AM4 Ryzen 3000, 5000 and the 3000/4000/5000 G-Series APUs, for example Ryzen 5 5600, Ryzen 7 5700X or Ryzen 5 5600G. Always check ASRock's CPU support list for the required BIOS version.
Does it support PCIe 4.0 SSDs?
Yes, the M.2 socket runs at PCIe Gen4 x4 with Ryzen 5000 and 3000 CPUs. With Ryzen 4000G/5000G APUs the socket runs at Gen3 speed.
Does the B550M-P have Wi-Fi?
No. It has 2.5GbE LAN; an M.2 Key E 2230 slot is available for an optional Wi-Fi/Bluetooth module.
What do I need to know before buying?
It uses DDR4 in two slots (max 64GB) and a single 4-pin 12V CPU connector, so it suits 65W-class Ryzen CPUs best. CPU, cooler, memory and SSD are sold separately.
Singular Expert Insight
The B550M-P makes sense when you want to keep costs down by staying on AM4 and DDR4 — for example a Ryzen 5 5600 gaming PC or a 5600G office machine — while still getting PCIe 4.0 and 2.5GbE. For a new build that should last longer, AM5 boards such as the A620AM-P or X870 Challenger WiFi add DDR5 and a newer upgrade path.
✓ Buy it if you are building a low-cost AM4 PC or reusing DDR4 memory and a Ryzen 5000 CPU.
✕ Skip it if you want DDR5, four memory slots or an upgrade path to Ryzen 9000.
→ Also consider ASRock A620AM-P for an entry AM5/DDR5 platform, or X870 Challenger WiFi for PCIe 5.0 and Wi-Fi 7.
