Verdict

The Gigabyte Z390 Gaming SLI is an ATX motherboard built for 8th and 9th Gen Intel Core processors, featuring an LGA 1151 socket and a 10+2 phase digital PWM design. Key specifications include four DDR4 DIMM slots supporting up to 128GB at speeds over 4266MHz (O.C.), dual M.2 slots (one with a Thermal Guard), and robust multi-GPU support for both 2-Way NVIDIA SLI and AMD CrossFire. It is praised for its high-end Realtek ALC1220-VB audio codec, Intel Gigabit LAN with cFosSpeed, and solid overclocking stability even under heavy loads like the i9-9900K. However, it lacks built-in Wi-Fi and Bluetooth connectivity, and the rear I/O is somewhat limited, notably missing a USB Type-C port and utilizing the older HDMI 1.4 standard.
