Verdict

The Gigabyte Z390 Gaming X is an ATX motherboard built for 8th and 9th Gen Intel Core processors, featuring a robust 10+2 phase digital VRM design and dual M.2 slots with a thermal guard for high-speed NVMe SSDs. Key characteristics include support for up to 128GB of dual-channel DDR4 memory (overclockable to 4266MHz), Intel Gigabit LAN with cFosSpeed, and RGB Fusion lighting for a customisable aesthetic. Its main pros are the reliable power delivery for 8-core CPUs, an integrated I/O shield for easier installation, and overall great value for a Z390 chipset board. However, it lacks a front-panel USB Type-C header, the second PCIe x16 slot only runs at x4 mode, and the BIOS interface can be unintuitive for new users compared to competitors.
