LGA 1200 Z490 ATX Motherboard

The ASUS ROG Maximus XII Hero (Wi-Fi) is an ATX motherboard built on the Intel Z490 chipset for LGA 1200 processors. It supports up to 128GB of DDR4 memory across four slots. The board includes integrated Wi-Fi connectivity and a premium power delivery design for stable operation. It is supplied as a new component with a chassis I/O back panel and one SATA cable.

Enthusiast builders needing maximum DDR4 capacity

This board suits builders who require the full 128GB DDR4 limit on the Z490 platform for heavy multitasking or content creation workloads. Buyers who need more storage interfaces than the provided SATA cable allows should consider their expansion requirements carefully. Systems requiring a smaller form factor than ATX will not fit this board.

128GB DDR4 maximum memory support

The single specification that decides fit is the 128GB DDR4 memory ceiling. If the planned build requires 128GB of system memory, this motherboard meets that requirement. If the workload demands memory capacity beyond 128GB, this Z490 board cannot accommodate it. Verify the CPU and memory kit compatibility before purchase.
