Asus Prime Z890M-Plus WiFi-CSM LGA1851 Micro ATX MotherboardCSM

The ASUS Prime Z890M-Plus WiFi-CSM is a Micro-ATX motherboard engineered for Intel Core Ultra Processors (Series 2) on the LGA1851 socket. Built around the Intel Z890 chipset, it delivers a tightly integrated platform for PC builders who need full-featured performance in a compact footprint. At its core, the board supports DDR5 memory in dual-channel configuration, with speeds reaching up to 8666 MT/s and beyond through ASUS Enhanced Memory Profile III (AEMP III) and Intel XMP. The maximum supported memory capacity is 256 GB across its DIMM slots, accommodating Clocked Unbuffered DIMMs (CUDIMMs) alongside standard unbuffered non-ECC DDR5 modules. Die ECC functionality is supported on compatible memory. Expansion is handled by a PCIe 5.0 x16 slot sourced from the CPU — ideal for the latest discrete graphics cards — supplemented by a chipset-driven PCIe 4.0 x16 slot (operating at x4 bandwidth) and two additional PCIe 4.0 x16 slots in x1 mode. Storage connectivity includes three M.2 Key-M slots and six SATA 6 Gb/s ports, giving builders ample room for high-speed NVMe drives alongside traditional storage. Wireless connectivity is provided by an integrated Wi-Fi 7 module paired with Bluetooth 5.4, enabling low-latency wireless networking. Wired networking is handled by a Realtek 2.5 Gb Ethernet controller. The rear I/O panel includes a USB 20 Gbps Type-C port with DisplayPort Alt Mode, one USB 10 Gbps Type-A port, four USB 5 Gbps Type-A ports, two USB 2.0 Type-A ports, a DisplayPort output, an HDMI port, three audio jacks, and a BIOS FlashBack button for convenient firmware updates without a CPU installed. Thermal management is addressed through onboard heatsinks and a comprehensive fan header layout, including dedicated CPU fan, CPU OPT, AIO Pump, and four chassis fan headers — all 4-pin. RGB enthusiasts are catered for with one Aura RGB header and three Addressable Gen 2 headers. A Thunderbolt (USB4) header, SPI TPM header, COM port header, and chassis intrusion connector round out the internal connectivity. The board carries a 3-year manufacturer warranty.
