ASUS Prime Z890-P Wifi CSM DDR5 Intel Motherboard

The ASUS Prime Z890-P WiFi CSM DDR5 is an ATX-form-factor motherboard built on the Intel Z890 chipset and designed specifically for Intel Core Ultra Processors (Series 2) in the LGA1851 socket. It strikes a practical balance between mainstream affordability and enthusiast-grade connectivity, making it a strong platform for PC builders who want future-proof storage, networking, and memory headroom without moving into the high-end desktop segment. On the memory side, four DDR5 DIMM slots support up to 192 GB of non-ECC unbuffered or CUDIMM memory in a dual-channel configuration. Overclocking headroom is substantial: ASUS's AEMP III firmware feature targets DDR5-8666 MT/s and beyond through a two-phase tuning process that first calibrates the clock driver and then the memory frequency. The companion DIMM Fit BIOS utility individually profiles each installed module to maximise compatibility and stability. Storage flexibility is a clear highlight. Four M.2 Key-M slots are provided: the primary CPU-connected slot (M.2_1) supports PCIe 5.0 x4 for sequential transfer rates up to 128 Gbps, while M.2_2 and M.2_3 both run PCIe 4.0 x4 at up to 64 Gbps. M.2_4, chipset-connected, accepts PCIe 4.0 x4 or SATA drives in 2242, 2260, and 2280 form factors. Four SATA 6 Gb/s ports round out the storage array, and Intel Rapid Storage Technology enables RAID 0, 1, 5, and 10 across SATA and PCIe drives. Connectivity is anchored by integrated Wi-Fi 7 (802.11be, 2×2, 2.4/5/6 GHz, 160 MHz, up to 2.9 Gbps) with Bluetooth 5.4, plus a Realtek 2.5 Gb wired Ethernet port protected by ASUS LANGuard. The rear I/O includes a Thunderbolt 4 USB Type-C port delivering up to 40 Gbps bidirectional bandwidth and support for up to one 8K@60Hz external display with DSC. Additional video outputs are a DisplayPort 1.4 (4K@60Hz) and an HDMI 2.1 port (4K@60Hz). The full rear USB complement spans eight ports: one Thunderbolt 4 Type-C, one USB 10 Gbps Type-A, two USB 5 Gbps Type-A, and four USB 2.0 Type-A. Power delivery employs a DIGI+ VRM with DrMOS technology backed by dual 8-pin CPU power connectors. Thermal management is handled by onboard M.2 and VRM heatsinks, six hybrid fan headers (including a dedicated AIO pump header), and ASUS Fan Xpert 4 software with AI Cooling II for automated temperature control. The BIOS FlashBack button on the rear I/O allows firmware updates without a CPU or RAM installed. Personalisation options include one Aura RGB header and three Addressable Gen 2 headers, all manageable through Armoury Crate software.
