GIGABYTE Z790 UD AC WiFi DDR5 Intel Motherboard

The Gigabyte Z790 UD AC is a full-size ATX motherboard built on the Intel Z790 chipset, designed for the LGA1700 socket and compatible with 12th, 13th, and 14th Generation Intel Core, Pentium Gold, and Celeron processors. It arrives with a robust power delivery system featuring a Twin 16+1+1 phase digital VRM solution, providing stable voltage regulation for demanding workloads and overclocking scenarios. Memory support is handled through four DDR5 DIMM slots in a dual-channel configuration, accepting up to 128 GB of system memory (up to 32 GB per DIMM). The board is compatible with DDR5 speeds from 4000 MHz up to 7600 MHz via overclocking profiles, with native support for Extreme Memory Profile (XMP) modules. Both ECC and non-ECC unbuffered DIMMs are accepted, giving system integrators added flexibility. Storage is well catered for with three PCIe 4.0 x4 M.2 connectors — one routed directly from the CPU and two from the chipset — all protected by Gigabyte's M.2 Thermal Guard heatsinks. Six SATA 6 Gb/s ports round out the storage options for traditional drives. The primary PCIe x16 slot runs at PCIe 5.0 bandwidth directly from the CPU, and it features Gigabyte's EZ-Latch mechanism for tool-free graphics card removal. Connectivity is a highlight: a Realtek 2.5GbE LAN chip delivers wired speeds up to 2.5 Gbps, while the onboard Intel Wi-Fi AC 9560 module supports 802.11a/b/g/n/ac on 2.4 GHz and 5 GHz dual-band frequencies with up to 1.73 Gbps throughput, accompanied by Bluetooth 5.1. The rear I/O panel includes a USB Type-C port with USB 3.2 Gen 2x2 (20 Gbps), a USB 3.2 Gen 2 Type-A port, four USB 3.2 Gen 1 ports, four USB 2.0 ports, HDMI 2.0 (up to 4096×2160 @ 60 Hz), DisplayPort 1.2 (up to 4096×2304 @ 60 Hz), and three audio jacks. An internal USB Type-C header adds front-panel USB 3.2 Gen 1 at 5 Gbps. Fan and thermal management is handled by Smart Fan 6, which monitors multiple temperature sensors across the board and supports hybrid fan headers with FAN STOP capability for silent operation under light loads. Two addressable RGB and two standard RGB LED headers allow system lighting customisation. The Q-Flash Plus button on the rear I/O enables BIOS updates without a CPU, memory, or graphics card installed — a practical feature when preparing for a new processor launch. The board ships with a 3-year manufacturer warranty.
