AI-Ready Platform

The ASUS PRIME Z890M-PLUS WIFI is an Intel Z890 micro-ATX motherboard built for Intel Core Ultra Processors (Series 2) on the LGA 1851 socket. It targets builders who want a compact foundation for advanced AI workloads and high-performance computing. Four DDR5 slots support up to 256 GB of memory in dual-channel mode.

Sustained Power Delivery

A 10+1+2+1 phase design uses 80 A DrMOS power stages with ProCool connectors on a six-layer PCB. Large VRM and PCH heatsinks work with hybrid fan headers and AI Cooling II to maintain thermal headroom during extended heavy loads. Fan Xpert 4 provides automated curve tuning for consistent stability.

PCIe 5.0 M.2 Slot

The primary M.2_1 slot (Key M, type 2280) connects directly to the CPU and runs at PCIe 5.0 x4 speeds for the fastest available storage throughput. Two additional chipset-linked M.2 slots operate at PCIe 4.0 x4. This configuration decides whether the board matches a build centred on next-generation SSD performance.

Questions about this item

Will this motherboard fit in a standard micro-ATX case and align with the I/O shield?

The board uses the micro-ATX form factor, so it mounts in any case that supports micro-ATX and uses the standard I/O cut-out.

Which CPUs are compatible with the LGA 1851 socket and Z890 chipset?

It supports Intel Core Ultra Processors (Series 2) only; earlier generations are not electrically compatible.

How many M.2 SSDs can I install and what speeds do the slots provide?

Three M.2 2280 slots are available: one runs at PCIe 5.0 x4 and two run at PCIe 4.0 x4.
