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.

What customers like about MSI B450M-A Pro Max II

  • Excellent value for budget-conscious builds
  • Out-of-the-box support for Ryzen 5000 series CPUs without needing a BIOS update
  • High-speed 2.5 Gbps Ethernet, which is rare for motherboards in this price range
  • Sleek all-black PCB design with a modern, user-friendly BIOS interface
  • Broad compatibility across the entire AM4 lineup (Ryzen 1000 to 5000 series)
  • Compact Micro-ATX form factor suitable for smaller PC cases

What customers don't like about MSI B450M-A Pro Max II

  • Lacks VRM heatsinks, which can lead to thermal throttling on high-core count CPUs (6+ cores) during heavy loads
  • Limited to only two RAM slots, which may restrict future memory upgrade paths
  • Only one M.2 slot and one system fan header, making it feel 'barebones' for advanced setups
  • Potential XMP compatibility issues where some users reported difficulty reaching 3200 MHz with specific RAM kits
  • Large GPU installs can physically block access to some SATA ports and the second PCIe slot
  • Does not support PCIe 4.0, sticking to the older PCIe 3.0 standard

Verdict

The MSI B450M-A Pro Max II is a budget-oriented Micro-ATX motherboard featuring the AMD B450 chipset and Socket AM4, supporting AMD Ryzen 1000 through 5000 series desktop processors. Key specifications include two DDR4 memory slots supporting up to 64GB at speeds up to 4133MHz (OC), one Turbo M.2 Gen3 x4 slot for NVMe SSDs, and four SATA 6Gb/s ports. Its main pros include high-speed 2.5G LAN for stable networking, 7.1-channel HD Audio with Audio Boost, and Core Boost technology for optimized power delivery to the CPU. However, it has some notable cons, such as being limited to PCIe 3.0 speeds, offering only two DIMM slots which limits future memory expansion, and lacking a VRM heatsink, which may lead to thermal throttling with higher core-count processors.
