Compact Z390 foundation

The ASUS PRIME Z390M-PLUS is a micro-ATX motherboard built around the Intel Z390 chipset and LGA 1151 socket. It accepts Intel Core 8th and 9th generation processors including Celeron, Pentium, Core i3, i5, i7 and i9 models. Four 288-pin DDR4 slots support dual-channel memory up to 128 GB with overclocked speeds reaching 4266 MHz.

Build focus and limits

This board suits builders who want a compact Z390 platform with two M.2 sockets, four SATA 6 Gb/s ports and a single full-length PCIe 3.0 x16 slot that can split into x8, x4, x4 configurations. A second x16 slot runs at x4 and two x1 slots round out expansion. Users needing integrated Wi-Fi, additional PCIe lanes or more than two M.2 drives should consider other models.

Deciding specification

The LGA 1151 socket paired with the Z390 chipset determines CPU compatibility and feature set. Only 8th and 9th generation Intel Core, Pentium and Celeron processors fit this socket, so the motherboard cannot be used with newer 10th generation or later CPUs. This single constraint decides whether the board matches the intended processor.

Questions about this item

Will my existing DDR4 memory work at its rated speed without overclocking?

The board runs DDR4 at 2133, 2400 and 2666 MHz natively; any higher frequency listed requires manual overclocking in the BIOS.

Can I install a 9th-generation Core i7 in this socket?

Yes, the LGA 1151 socket supports Intel Core 9th Gen processors alongside 8th Gen, Core i3, i5, i9, Pentium and Celeron CPUs.

How many M.2 drives can I fit at once?

Two M.2 slots are available, so you can populate both simultaneously.
