What it is
Our main score for this model, 1–10. It combines specs, expert reviews, best-of lists, owners and ratings from across the web.
How we count it
Parts: Technical score 40%, Reviews score 20%, List score 20%, Sentiment score 10%, User score 10%
Marks: Each part gets a mark out of 10. For reviews, lists and owners, a typical model in this category gets about 8 and the best one gets 10.
No data yet: A part with no data shows "?". It counts as the mark of a weaker model in this category (4 in 5 models with data score higher). This way, models with reviews, lists and owners usually come out ahead.

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 ASUS Prime B650M-A

  • Stable performance with no spontaneous reboots or Blue Screens of Death (BSOD) reported by many users
  • Effective cooling performance when paired with standard air coolers
  • Quick boot times for some users once initial setup is complete
  • Generous connectivity including 2.5Gb Ethernet and PCIe 5.0 M.2 support
  • BIOS FlashBack feature allows for easy BIOS updates without a CPU installed
  • Comprehensive I/O for a budget-friendly board, including front USB Type-C support

What customers don't like about ASUS Prime B650M-A

  • Long POST times (up to 40 seconds) due to memory training on the AM5 platform
  • Potential stability issues when attempting to run RAM at high overclocked speeds (e.g., 6000MHz+)
  • Spotty Bluetooth and Wi-Fi connectivity reported on wireless-enabled variants
  • Entry-level VRM design may run hot under heavy loads with high-end Ryzen 9 processors
  • Lacks a pre-installed I/O shield and uses a more basic audio codec (ALC897)
  • Occasional BIOS/UEFI bugs that can make initial configuration or updates frustrating

Verdict

The ASUS Prime B650M-A is a Micro-ATX motherboard designed for AMD Socket AM5, supporting Ryzen 9000, 8000, and 7000 series processors. It features four DDR5 DIMM slots (up to 128GB/192GB and 7600+ MHz OC), two M.2 slots (one supporting PCIe 5.0 x4), and dual PCIe 4.0 x16 expansion slots. Connectivity is highlighted by a Realtek 2.5Gb Ethernet port, USB 3.2 Gen 2 (10Gbps) Type-A rear ports, and a front-panel USB 3.2 Gen 1 Type-C connector. Key pros include its future-proof PCIe 5.0 storage support, robust cooling with VRM and PCH heatsinks, and user-friendly features like BIOS FlashBack and Aura Sync RGB headers. However, notable cons include the lack of built-in Wi-Fi/Bluetooth on this specific model and a relatively basic power delivery system that may limit extreme overclocking on high-end CPUs.
