Socket LGA 1700 ATX board

This ATX motherboard uses the Intel Z790 chipset and an LGA 1700 socket for 12th and 13th generation Intel Core, Pentium Gold and Celeron processors. It targets PC builders who want a full-size platform with current-gen connectivity and room for expansion.

Build quality and daily connectivity

A 16+1+1 phase Duet Rail power system with 90 A smart power stages feeds the CPU through dual 8-pin connectors. The board carries an extended VRM heatsink, 7 W/mK thermal pads, a six-layer PCB with thickened copper and M.2 Shield Frozr cooling for storage. Rear I/O includes Wi-Fi 6E, 2.5 Gbps LAN, Realtek ALC4080 7.1-channel audio, USB 3.2 Gen 2x2 20 Gbps and multiple USB 3.2 Gen 1 ports.

Memory ceiling and PCIe 5.0 graphics slot

Four DDR5 slots support up to 192 GB in dual channel with XMP 3.0 profiles reaching 7200 MHz. The primary PCIe 5.0 x16 slot runs from the CPU for next-generation graphics cards, while four M.2 Key M slots and seven SATA 6 Gb/s ports provide abundant high-speed storage options.

Questions about this item

What speed does the PCIe 5.0 x16 slot deliver in practice?

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

What clearance and form factor does the board need to fit in a case?

The ATX form factor requires a case with ATX mounting holes and enough height for the extended VRM heatsink and M.2 shields.

How is the BIOS updated and which step is often missed?

Use the rear Flash BIOS Button with a USB drive inserted in the dedicated BIOS port; the step often missed is renaming the BIOS file to the exact name required by the board.
