Silver-white Z790 ATX motherboard

The ASUS ROG Strix Z790-A Gaming WiFi S is an Intel LGA 1700 board built around the Z790 chipset. It targets enthusiasts who want a clean silver-and-white aesthetic and AI-assisted overclocking for 12th, 13th and 14th generation Core processors. A 16+1+2 phase 70A DrMOS power design supports heavy CPU loads, while Polymo lighting and AURA Sync handle the visual side.

Expansion layout and connectivity

One PCIe 5.0 x16 slot takes the graphics card and a second chipset-linked slot runs at PCIe 4.0 x4. Five M.2 sockets accept 2242, 2260, 2280 and 22110 modules, with the top slot wired to the CPU at PCIe 4.0 x4. Four SATA 6Gb/s ports remain available for additional storage. Rear I/O delivers 5Gbps and 2.5Gbps Ethernet, WiFi 7, Bluetooth 5.4, 7.1-channel audio and twelve USB ports including one 20Gbps Type-C and three 10Gbps ports.

Memory capacity and headroom

Four DDR5 slots support up to 192GB in dual-channel mode. The board validates speeds beyond DDR5-8000 via XMP, AEMP II and DIMM Flex, which adjusts timing based on module temperature. OptiMem II routing helps maintain signal integrity at high frequencies. Headroom ends at the 192GB limit and at the maximum data rate your specific memory kits can sustain.

Questions about this item

How much power can the 16+1+2 phase 70A DrMOS VRM deliver before thermal throttling under sustained load?

The 16+1+2 phase 70A DrMOS design is rated to handle an i9-14900K at full load, with VRM dual heatsinks, heat pipes and AI Cooling II managing thermals continuously.

What are the VRM and M.2 temperatures and fan noise like when the board runs all day with AI Cooling II active?

AI Cooling II auto-tunes every 4-pin header — CPU, CPU OPT, AIO pump and five chassis fans — while dual VRM heatsinks, heat pipes and double-sided M.2 thermal armour keep component temperatures low and acoustics quiet.

Which DDR5 memory kit speeds and capacities are validated for the 192 GB four-slot limit on this board?

Four 288-pin DDR5 slots support up to 192 GB total; the board validates DDR5-8000+ overclocking via XMP, DIMM Flex and AEMP II, with exact kit compatibility listed in the ASUS QVL.
