What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.8 for now.

Third-party reviews

What customers like about MSI B550M-A Pro

  • Excellent value for money for budget AM4 builds
  • Stable performance when paired with Ryzen 5000 series CPUs (e.g., 5600, 5700X)
  • Supports PCIe 4.0 for faster NVMe storage and modern GPUs
  • Effective heat dissipation due to 2oz thickened copper PCB design
  • Reliable VRM performance that avoids throttling under standard workloads
  • Compact Micro-ATX form factor suitable for smaller PC cases

What customers don't like about MSI B550M-A Pro

  • Lacks built-in Wi-Fi and Bluetooth connectivity
  • Minimalist design with no integrated RGB lighting
  • Sparse rear I/O connectivity with limited USB ports
  • Basic onboard audio and networking controllers (Realtek 8111H)
  • Only a 4-pin CPU power connector, which may limit heavy overclocking on high-end chips
  • Requires a BIOS update for some newer Ryzen 5000 series processors

Verdict

The MSI B550M-A PRO is a budget-friendly Micro-ATX motherboard designed for the AMD AM4 socket, officially supporting 3rd Gen Ryzen and 5000 Series desktop processors. It features two DDR4 DIMM slots supporting up to 64GB of memory at speeds up to 4600MHz (OC), one PCIe 4.0 x16 slot for modern graphics cards, and a Lightning Gen4 x4 M.2 slot for high-speed NVMe storage. Main pros include its compact form factor, affordable entry point into the B550 chipset, and reliable performance through Core Boost and a 2oz thickened copper PCB. However, its notable cons include a limited expansion capability with only two RAM slots, a relatively basic VRM design without dedicated heatsinks, and a lack of built-in Wi-Fi or USB Type-C connectivity.
