Z790 ATX Motherboard for Intel LGA 1700

This ASUS ROG Strix board pairs the Intel Z790 chipset with an LGA 1700 socket for 12th, 13th and 14th generation Core processors. It delivers a 16+1+2 phase power design using 70A DrMOS stages and AI overclocking assistance. Four DDR5 slots support up to 192GB of memory with XMP, DIMM Flex and AEMP II profiles.

PCIe 5.0 Graphics Slot and Five M.2 Interfaces

A single PCIe 5.0 x16 slot connects directly to the CPU for the graphics card, while the chipset adds one PCIe 4.0 x16 slot running at x4 and one PCIe 3.0 x1 slot. Five M.2 slots accept 2242, 2260, 2280 and 22110 form factors; the top slot runs at PCIe 4.0 x4 from the processor and the remainder are wired through the Z790 chipset. Four SATA 6Gb/s ports remain available for additional drives.

DDR5 Memory Support Up to 192GB

The board provides four 288-pin DDR5 slots with a maximum capacity of 192GB in dual-channel mode. Supported data rates and module counts depend on the specific processor and memory kits installed. AI cooling and VRM thermal armour help sustain high-frequency operation during extended workloads.

Questions about this item

Which DDR5 kit should I pick for this board?

The board has four DDR5 slots supporting up to 192 GB total and speeds beyond 8000 MT/s with XMP, AEMP II and DIMM Flex; populate all four slots for maximum capacity or two slots for the highest frequencies.

What does the 16+1+2 phase 70 A DrMOS design mean for daily use?

It delivers stable power to 14th, 13th and 12th Gen Intel Core processors, allowing sustained boost clocks and headroom for AI-assisted overclocking without VRM throttling.

How fast are the M.2 slots and what limits them?

One slot runs at PCIe 5.0 x4 from the CPU while four run at PCIe 4.0 x4 from the Z790 chipset; each is covered by full thermal armour to prevent throttling.
