The Gigabyte Z790 D is built around the LGA 1700 socket and is compatible with the Z790 chipset, housed in a standard ATX form factor measuring 305 mm by 244 mm. It features a single CPU socket and does not include an integrated CPU or integrated graphics, so a discrete GPU is required for display output. The board supports HDMI 2.1 and is noted as easy to overclock, while also including RGB lighting. Wi-Fi and Bluetooth are not present, meaning wired networking is the only built-in connectivity option. Dual BIOS is not supported, and the BIOS reset process is not listed as simplified. The board carries a 3-year warranty.
The board supports DDR5 memory across four slots in a dual-channel configuration, with a maximum capacity of 192 GB. Standard RAM speeds top out at 5600 MHz, while overclocking allows speeds of up to 7600 MHz for users who want to push memory performance further. ECC memory is not supported, so the board is oriented toward standard consumer use rather than workstation or server applications.
The rear I/O panel provides a reasonable spread of USB connectivity, including one USB 3.2 Gen 2 Type-A port, four USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2 Type-C port, and two USB 2.0 ports. Higher-bandwidth options such as USB 3.2 Gen 2x2, USB 4, Thunderbolt 3, and Thunderbolt 4 are not present. Display output is handled through one HDMI port and one DisplayPort output, while VGA and DVI are absent. Networking is covered by a single RJ45 port, and a PS/2 port is also included for legacy input devices. eSATA is not available on this board.
Internal connectivity on the Gigabyte Z790 D includes three M.2 sockets for NVMe or SATA-based storage drives, along with four SATA 3 connectors for traditional storage devices; SATA 2 and mSATA are not available. For USB expansion via headers, the board offers two USB 3.2 Gen 1 connectors, two USB 3.0 connectors, and four USB 2.0 connectors, allowing additional ports to be added through the chassis. Six fan headers provide ample control over system cooling, and a TPM connector is present for hardware-based security modules. U.2 sockets are not included.
The board offers a capable set of expansion slots, anchored by one PCIe 5.0 x16 slot for the primary graphics card or other high-bandwidth devices, complemented by one PCIe 4.0 x16 slot and one PCIe 3.0 x16 slot for additional cards. Two PCIe x1 slots are also available for smaller expansion cards. Legacy PCI slots are not present, and there are no PCIe 2.0 x16, x4, or x8 slots on this board.
The onboard audio supports 7.1-channel surround sound and is accessible through three analog audio connectors on the rear I/O. An S/PDIF optical output is not included, so digital audio passthrough via that interface is not an option on this board.
The board supports a broad range of RAID configurations, including RAID 0, 1, 5, and 10, giving users flexibility in balancing performance, redundancy, or a combination of both across connected storage drives. RAID 0+1 is not supported.
