Verdict

The Gigabyte Z390 M is a Micro-ATX motherboard designed for 8th and 9th Gen Intel Core processors, featuring the LGA 1151 socket and Intel Z390 chipset. Key specifications include support for up to 128GB of dual-channel DDR4 memory (overclocked to 4266MHz), dual NVMe PCIe Gen3 x4 M.2 slots, and a 10+2 phase digital PWM design for stable power delivery. It offers versatile connectivity with Intel GbE LAN, USB 3.1 Gen 2 (Type-A and Type-C), and Thunderbolt 3 AIC support, while the Ultra Durable design provides reinforced PCIe slots and surge protection. Its primary pros are its compact form factor combined with high-end overclocking capabilities and robust thermal management through Smart Fan 5. However, it lacks built-in Wi-Fi and Bluetooth, and its older HDMI 1.4 version limits 4K output to 30Hz.

What customers dislike about GIGABYTE Z390 M?

  • Tight layout can cause clearance issues between large CPU coolers and the primary GPU slot
  • No integrated ARGB support (users looking for this must step up to the 'Gaming' version)
  • Included software/bloatware (Gigabyte App Center) is often described as clunky or unnecessary
  • Physical build quality of small components, like fan headers or M.2 screws, can feel flimsy to some users
  • Lack of built-in Wi-Fi on the base model requires an additional card or choosing the Wi-Fi specific variant
