Verdict

The Gigabyte Z790 Aorus Tachyon is an E-ATX motherboard purpose-built for extreme overclocking, featuring a robust direct 15+1+2 phase digital VRM with 105A power stages and tantalum polymer capacitors for superior voltage stability. It supports Intel 12th, 13th, and 14th Gen processors on the LGA 1700 socket and utilizes a specialized two-DIMM memory layout to achieve DDR5 speeds up to 8333MHz+. Connectivity highlights include dual PCIe 5.0 x16 slots, four PCIe 4.0 M.2 sockets, Intel Wi-Fi 6E, 2.5GbE LAN, and dual USB-C 20Gb/s ports. While its dedicated onboard overclocking kit and 'OC Ignition' feature are major pros for enthusiasts, its specialized nature leads to notable cons such as having only two RAM slots (limiting total capacity to 96GB or 128GB depending on the revision) and a high price point that targets a niche professional audience.
