ROG MAXIMUS Z790 EXTREME for LGA 1700

The ASUS ROG MAXIMUS Z790 EXTREME is an Intel motherboard built on the Z790 chipset for LGA 1700 processors. It supports DDR5 memory up to 192GB in an E-ATX form factor. The board arrives new and includes a rear I/O shield plus one SATA cable.

Suits high-capacity DDR5 builds.

This board suits builders who need the 192GB DDR5 ceiling and the Z790 feature set for an LGA 1700 CPU. The E-ATX dimensions mean it will not fit in cases limited to standard ATX or smaller layouts. Buyers who need a smaller footprint should look at a different form factor.

192GB DDR5 maximum decides the build

The single specification that determines fit is the 192GB DDR5 memory limit. If the planned workload requires more memory than this ceiling allows, this motherboard cannot meet the requirement and a different platform must be chosen.

Questions about this item

How much DDR5 memory can the ROG MAXIMUS Z790 EXTREME support before hitting the ceiling?

The board accepts up to 192 GB of DDR5, so that capacity limit is the first constraint you reach under sustained heavy workloads.

What thermal or acoustic behaviour should I expect when the Z790 chipset runs all day?

With only the chipset and VRM areas active continuously, heat output stays moderate and the stock cooling keeps noise low during extended sessions.

Which storage cable must I already have to connect a SATA drive to this motherboard?

One SATA cable is included in the box, so you can attach a SATA drive immediately without sourcing an extra cable.
