Micro ATX board for 10th and 11th Gen Intel Core

The ASUS PRIME Z490M-PLUS fits an LGA 1200 socket and the Intel Z490 chipset into a Micro ATX layout. It targets builders who want a compact platform for 10th and 11th Gen Intel Core i9, i7, i5 or i3 processors. Four DDR4 slots and dual M.2 sockets provide expansion room inside smaller cases.

128 GB DDR4 ceiling with wide overclock range

Four 288-pin slots accept up to 128 GB of non-ECC unbuffered DDR4. Native speeds reach 2933 MHz on 10th Gen i9 and i7 CPUs; the board validates overclocked steps from 3000 through 4400 MHz. Two channels keep bandwidth balanced. Memory runs out when all slots are populated at the highest frequencies or when a kit exceeds the qualified vendor list.

Dual M.2 plus display outputs for integrated

The first M.2 socket takes 2242, 2260, 2280 and 22110 modules on a PCIe 3.0 x4 link. The second accepts 2242, 2260 or 2280 drives in either SATA or PCIe 3.0 x4 mode. Rear I/O includes DisplayPort 1.4, HDMI 1.4b and DVI-D, enabling video from CPUs with integrated graphics. Fan Xpert 4 and hybrid headers let software tune cooling curves.

Questions about this item

Will my existing DDR4 2666 MHz memory work with the PRIME Z490M-PLUS?

Yes, the board natively supports DDR4 2666 MHz modules in its four 288-pin slots up to 128 GB total.

How can I confirm the Realtek ALC887 audio is functioning after assembly?

Connect speakers to the three rear audio jacks, install the Realtek driver, and verify 8-channel output in Windows Sound control panel.

Does the box include M.2 mounting screws or must I buy them separately?

The retail package supplies the M.2 standoffs and screws; no separate purchase is needed for the two Key M slots.
