Reviews last updated: May 2026 · How we calculate this

What we like about ASRock B660M ITX AC

  • One of the most affordable Mini-ITX options for Intel 12th/13th Gen
  • Includes built-in Dual Band 802.11ac Wi-Fi and Bluetooth
  • Features a front-panel USB 3.2 Gen1 Type-C header
  • Performs reliably when paired with budget-friendly CPUs like the i3-12100 or i5-12400
  • Compact form factor is ideal for space-constrained SFF (Small Form Factor) builds
  • Supports DDR4 memory, allowing for lower total system build costs

What we don't like about ASRock B660M ITX AC

  • Extremely limited rear I/O with few USB ports
  • Only one M.2 NVMe slot available for storage expansion
  • Weak VRM design limits performance on high-end CPUs (e.g., i7 or i9) due to power throttling
  • Lacks a pre-installed I/O shield and M.2 heatsink
  • No diagnostic LED error lights to help with troubleshooting boot issues
  • The basic aesthetic and 'hideous' green/brown PCB design are frequently cited as negatives

Verdict

The ASRock B660M-ITX/ac is a budget-friendly Mini-ITX motherboard featuring the Intel LGA1700 socket to support 12th, 13th, and 14th Gen processors. Key specifications include a 6-phase Dr.MOS power design, two DDR4 DIMM slots supporting up to 64GB at 5000+MHz (OC), one PCIe 4.0 x16 slot, and a Hyper M.2 slot for high-speed Gen4x4 NVMe storage. Its main pros are the inclusion of built-in dual-band 802.11ac Wi-Fi, Bluetooth, and a front-panel USB 3.2 Gen1 Type-C header, making it an excellent value for compact builds. However, notable cons include a limited expansion suite with only one M.2 slot, no USB Type-C port on the rear I/O, and VRM thermal limitations that may require undervolting or direct airflow when paired with higher-end CPUs like the i5-12600K.
