Verdict

The ASRock H670M-ITX/ax is a compact Mini-ITX motherboard supporting 12th, 13th, and 14th Gen Intel Core processors on the LGA1700 socket, featuring an 8-phase Dr.MOS power design and a high-speed PCIe 5.0 x16 slot. It offers dual-channel DDR4 support up to 5000MHz (OC), dual Hyper M.2 slots (PCIe Gen4x4), and robust connectivity including Wi-Fi 6E, Bluetooth 5.3, and Dragon 2.5G LAN. Main pros include its relatively affordable price for the ITX form factor, excellent high-speed I/O such as the rear USB 3.2 Gen2x2 Type-C (20Gbps), and a lack of bulky heatsinks that ensures broad CPU cooler compatibility. However, notable cons include a lack of VRM heatsinks which can lead to thermal throttling under high power draws, and a BIOS-enforced 125W power limit that may restrict the performance of high-end, unlocked processors.

What customers like about ASRock H670M ITX AX?

  • Competitive pricing for a Mini-ITX board with PCIe 5.0 support
  • Dual M.2 slots (one PCIe 4.0 x4) and 2.5G LAN provide excellent connectivity for its size
  • Lower-profile heatsinks offer great compatibility with various CPU air and liquid coolers
  • Solid performance when paired with mid-range CPUs like the i5-12400 or i5-12600K
  • Clean, utilitarian design without excessive RGB lighting

What customers dislike about ASRock H670M ITX AX?

  • Power limits (roughly 125W-150W) make it unsuitable for high-end 'K' series i7 or i9 CPUs
  • Weak VRM cooling with some phases lacking heatsinks, leading to potential thermal throttling under heavy loads
  • Reported instability or random disconnections with the second M.2 slot on some units
  • Initial driver issues, specifically with the Wi-Fi adapter not being detected out of the box
  • Requires a BIOS update for compatibility with 13th Gen Intel processors
