Overview
The ASUS Prime Z490M-Plus is a Micro-ATX motherboard built around the Intel Z490 chipset and LGA 1200 socket, designed to support 10th Generation Intel Core, Pentium Gold, and Celeron processors with Intel 14 nm architecture. Its robust 8+1 DrMOS power-stage design, combined with a 6-layer PCB, ProCool connector sockets, alloy chokes, and durable capacitors, delivers stable and efficient power to high-core-count CPUs under sustained workloads. Memory flexibility is a strong suit: four DDR4 DIMM slots accept up to 128 GB of non-ECC unbuffered RAM in dual-channel configuration, with native speeds of 2133–2666 MHz on 10th Gen Core i9/i7 CPUs and overclocked profiles reaching up to DDR4-4400 via XMP. ASUS OptiMem technology carefully routes PCB traces and vias to maintain signal integrity during memory overclocking. Storage options include two M.2 Socket 3 slots—one supporting up to 22110 form factors at PCIe 3.0 x4 speeds, and a second supporting 2242/2260/2280 devices in either SATA or PCIe 3.0 x4 mode—alongside five SATA 6 Gb/s ports with RAID 0/1/5/10 support and Intel Optane Memory readiness. Connectivity is handled by an Intel I219-V Gigabit Ethernet controller and a comprehensive USB layout: the rear I/O panel provides two USB 3.2 Gen 2 ports (one Type-A, one Type-C), two USB 3.2 Gen 1 Type-A ports, and two USB 2.0 ports, while internal headers add four USB 3.2 Gen 1 and four USB 2.0 front-panel ports. Display outputs include DisplayPort 1.4 (up to 4096×2304 at 60 Hz), HDMI 1.4b, and DVI-D for systems using integrated graphics. Thermal management relies on VRM heatsinks with thermal pads, plus four hybrid fan headers (1 CPU, 3 chassis) and an AIO pump header, all controllable via Fan Xpert 4 software. Audio is delivered through a Realtek ALC887 8-channel HD codec with dedicated PCB layers, audio shielding, and premium Japanese capacitors for up to 24-bit/192 kHz playback. The ASUS 5X Protection III suite includes DIGI+ VRM with DrMOS, LANGuard surge protection, overvoltage protection, SafeSlot Core reinforced PCIe slots, and a stainless-steel rear I/O panel. BIOS is a 128 Mb Flash ROM UEFI AMI implementation accessible via the intuitive EZ Mode interface, CrashFree BIOS 3, and EZ Flash 3 for firmware updates.
