ASUS ROG Maximus XIII Extreme Intel Z490 motherboard

The ASUS ROG Maximus XIII Extreme is an Intel Z490 motherboard built for the LGA 1200 socket. It supports DDR4 memory up to 128GB and uses an E-ATX form factor. The package includes the board, a metal battery, a SATA cable, and a chassis I/O back panel.

Suited for high-end LGA 1200 builds needing

This board fits enthusiasts building around the Z490 chipset who require 128GB memory headroom and an E-ATX layout. It is not for builders using a different CPU socket, those needing a smaller form factor, or buyers who require original packaging and a full accessory bundle.

128GB DDR4 maximum memory supported

The decisive specification is the 128GB DDR4 memory ceiling. If your workload demands that capacity on the Z490 platform, this board meets it; if you need more memory than 128GB, this is not the right part.
