Third-party reviews

What customers like about ASUS ROG Strix Z390-I Gaming

  • Excellent cooling performance with large heatsinks for an ITX board
  • Dual M.2 slots (one on front with heatsink, one on back)
  • Strong power delivery capable of handling high-end CPUs like the i9-9900K
  • High-quality integrated audio (SupremeFX S1220 codec)
  • Neutral aesthetic with customizable RGB lighting that fits most builds
  • Includes a variety of internal headers (USB 2.0, 3.1, and 3.1 Gen 2)
  • Pre-mounted I/O shield makes installation easier

What customers don't like about ASUS ROG Strix Z390-I Gaming

  • Significantly higher price point compared to other Z390 ITX competitors
  • Awkward placement of front panel and USB 2.0 headers above the PCIe slot
  • VRM design (twin-phase) is sometimes debated by enthusiasts for missing doublers
  • Cybertext patterning on the PCB and I/O cover may not appeal to all users
  • Potential clearance issues with some large CPU air coolers or AIO blocks due to tall heatsinks
  • Reported instances of long-term reliability issues (e.g., failure to POST after several months)

Verdict

The ASUS ROG Strix Z390-I Gaming is a premium Mini-ITX motherboard featuring the Intel Z390 chipset and an LGA 1151 socket, supporting 8th and 9th Generation Intel Core processors. Despite its compact 17cm x 17cm form factor, it offers high-end performance characteristics including dual PCIe 3.0 x4 M.2 slots (one with a double-decker heatsink), Intel 2x2 802.11ac Wi-Fi with MU-MIMO, and support for up to 64GB of DDR4 memory via unique double-capacity DIMM technology. Main pros include a robust VRM with DrMOS power stages for stable overclocking, SupremeFX S1220A audio, and a pre-mounted I/O shield for easier installation. However, notable cons include its high retail price relative to other ITX boards, a limited number of fan headers (only three), and the potential for a cramped layout that can make certain headers difficult to access in small cases.
