Socket LGA 1700 Z790 motherboard

This ATX board uses the Intel Z790 chipset and the LGA 1700 socket to support 12th and 13th generation Intel Core processors plus Pentium Gold and Celeron CPUs. Four 288-pin DDR5 slots accept up to 192 GB in dual-channel mode with XMP 3.0 profiles. A PCIe 5.0 x16 slot connects directly to the CPU for the latest graphics cards.

Quad M.2 slots and 2.5 Gbps LAN

Four Key M M.2 connectors provide flexible storage expansion; the CPU-linked M2_1 slot runs at PCIe 4.0 x4 and fits 2260, 2280 or 22110 drives. A shielded thermal cover helps keep SSDs cool under load. Seven SATA 6 Gb/s ports add further capacity, while an Intel 2.5 Gbps Ethernet controller and pre-installed Wi-Fi 6E module cover wired and wireless networking.

Check CPU generation and BIOS before ordering

Some 14th generation Intel Core processors may require a BIOS update, so verify the board revision or plan an update path. Confirm that your chosen DDR5 kit matches the supported speed table for one or two DIMMs per channel. Ensure your case fits an ATX form factor and that the power supply provides the required EPS connectors.

Questions about this item

What PCIe generation does the primary x16 slot use, and what bandwidth does that cap at?

The primary PCI_E1 slot runs at PCIe 5.0 x16 directly from the CPU, delivering up to 128 GB/s of bandwidth for graphics or accelerator cards.

What physical clearance does the board require for its M.2 heatsinks and ATX mounting?

The board uses the standard ATX mounting pattern and includes M.2 Shield Frozr heatsinks that add height over the four Key M slots; verify your case and CPU cooler clearances before fitting double-sided 22110 drives.

How is the Wi-Fi 6E module installed, and what step do builders often miss?

The Intel Wi-Fi 6E module comes pre-installed in the M.2 Key-E slot; the step many miss is attaching the two external antenna cables to the gold connectors on the module before closing the case.
