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 don't like about ASRock B550M-ITX/ac

  • Only one M.2 slot for storage expansion
  • VRM heatsink is relatively small and may struggle with high-TDP CPUs or overclocking
  • Lacks BIOS Flashback, making updates difficult without a compatible CPU
  • No front-panel USB-C header (only rear USB-C)

  • Some users reported weak Wi-Fi signal or Bluetooth connectivity issues
  • Basic aesthetics with a simple, stamped metal I/O shield

Verdict

The ASRock B550M-ITX/ac is a compact Mini-ITX motherboard featuring the AMD B550 chipset and AM4 socket, supporting Ryzen 3000, 4000 G-Series, and 5000 series processors. It is equipped with an 8-phase power design, 60A power chokes, and a 50A Dr.MOS solution to ensure stable delivery for high-performance CPUs. Key specifications include two DDR4 slots supporting up to 64GB at 4733MHz (OC), one PCIe 4.0 x16 slot, and a Hyper M.2 slot that also supports PCIe Gen4 x4 speeds. For connectivity, it offers built-in 802.11ac Wi-Fi, Bluetooth 4.2, and a rear I/O with HDMI 2.1 (4K @ 60Hz), DisplayPort 1.4, and USB 3.2 Gen1 Type-C. Main pros include its excellent value for small form factor builds, PCIe 4.0 support for modern GPUs/SSDs, and robust VRM cooling for its price point. However, notable cons include the presence of only a single M.2 slot, lack of a front-panel USB-C header, and the use of older Wi-Fi 5 and Bluetooth 4.2 standards instead of the more recent Wi-Fi 6.
