ASUS Prime Z890-P CSM DDR5 Intel Motherboard

The ASUS Prime Z890-P CSM DDR5 is an ATX-form-factor motherboard built around the Intel Z890 chipset, designed to support Intel Core Ultra Processors (Series 2) via the LGA1851 socket. It targets PC builders, content creators, and AI workstation users who need a reliable, feature-rich platform with modern connectivity and forward-looking storage support. At the heart of the power delivery system sits a 14+1+2+1 power stage design, with each stage rated at 80 amperes, delivering stable and efficient power to high-core-count Intel processors. This robust VRM arrangement is complemented by dedicated VRM heatsinks and multiple onboard thermal solutions to maintain system stability under sustained workloads. Memory support extends to four DDR5 DIMM slots with a maximum capacity of 192GB. The board is compatible with Clocked Unbuffered DIMMs (CUDIMMs) and supports speeds up to DDR5-8666+ MT/s under overclocking via ASUS Enhanced Memory Profile III (AEMP III) and Intel XMP. The DIMM Fit BIOS feature analyses individual memory modules to optimise compatibility and performance. Storage is well catered for with four M.2 slots: the primary M.2_1 slot (PCIe 5.0 x4) delivers up to 128Gbps, while M.2_2, M.2_3, and M.2_4 operate at PCIe 4.0 x4 (up to 64Gbps each). Four SATA 6Gb/s ports offer additional drive connectivity. Intel Rapid Storage Technology enables RAID 0/1/5/10 across PCIe and SATA arrays. Expansion options include one PCIe 5.0 x16 slot from the CPU, two PCIe 4.0 x16 slots (operating at x4 mode), and one PCIe 4.0 x16 slot (x1 mode) from the chipset. Rear I/O provides a USB 20Gbps Type-C port with DisplayPort Alt Mode (4K@120Hz), one USB 10Gbps Type-A, two USB 5Gbps Type-A, four USB 2.0 Type-A ports, a DisplayPort 1.4 output (4K@60Hz), an HDMI 2.1 port (4K@60Hz), Realtek 2.5Gb Ethernet with LANGuard, three audio jacks, and a BIOS FlashBack button for tool-free firmware updates. Audio is handled by a Realtek 7.1 Surround Sound HD Audio CODEC supporting up to 24-bit/192kHz playback, with audio shielding and dedicated PCB layers for improved signal clarity. The board includes a Thunderbolt (USB4) header, three Addressable Gen2 headers, one Aura RGB header, and fan/pump headers for comprehensive cooling control via ASUS Fan Xpert 4 software. NPU Boost — available for Intel K-series processors — allows BIOS-level overclocking of the integrated NPU in supported Intel Core Ultra Series 2 CPUs, increasing NPU performance by up to 24% according to ASUS specification data.
