Verdict

The ASRock H670 Steel Legend is a durable ATX motherboard designed for 12th, 13th, and 14th Gen Intel Core processors on the LGA1700 socket, featuring a 9-phase Dr.MOS power design and a 6-layer PCB for stable performance. Key specifications include a PCIe 5.0 x16 slot for next-gen graphics, four DDR4 DIMM slots supporting dual-channel memory up to 5333+(OC), and triple Hyper M.2 slots (PCIe Gen4x4) with full-coverage heatsinks. It excels with robust connectivity like Dragon 2.5G LAN, a front panel USB 3.2 Gen2x2 Type-C (20 Gb/s) header, and Nahimic Audio for immersive sound. Main pros include its solid VRM cooling, BIOS Flashback button for easy updates, and support for high-speed PCIe 5.0 devices at a mainstream price point; however, notable cons include the lack of built-in Wi-Fi (though an M.2 Key-E slot is provided), reliance on the older DDR4 standard which limits future memory scaling, and the use of the aging Realtek ALC897 audio codec.

What customers like about ASRock H670 Steel Legend?

  • Affordable pricing compared to competitors with similar chipset features
  • Support for PCIe 5.0 on the primary x16 slot, providing future-proofing for next-gen GPUs
  • Includes BIOS Flashback feature, allowing for BIOS updates without a CPU or RAM installed
  • Sturdy 6-layer PCB and Dr. MOS power phase design for stable power delivery and better thermals
  • Equipped with three M.2 slots for high-speed NVMe storage
  • Includes a POST status LED cluster to help with troubleshooting during the boot process
  • Support for DDR4 memory allows users to reuse existing RAM and save on total build costs

What customers dislike about ASRock H670 Steel Legend?

  • Lack of integrated Wi-Fi or Bluetooth out of the box (requires a separate M.2 Wi-Fi card)
  • No support for CPU or BCLK overclocking, which is a limitation of the H670 chipset
  • The audio solution uses an older ALC897 codec, which may not satisfy high-end audio enthusiasts
  • M.2 slot placement is not ideal, with some slots sitting directly under the GPU without dedicated heat shields
  • Does not feature a 20Gbps USB port on the rear I/O, only providing an internal header for one
  • DDR4 support, while cost-effective, limits future top-end performance compared to newer DDR5 platforms
