AI-Ready Platform

The ASUS PRIME Z890-P WIFI motherboard paired with the Intel Core Ultra 9 285K CPU targets builders who want an advanced AI PC foundation. The LGA 1851 socket accepts Intel Core Ultra Processors Series 2, while the Z890 chipset unlocks high-speed connectivity. Four DDR5 slots support up to 256GB of memory running at 8666+ MT/s when overclocked. This combination delivers the throughput needed for demanding AI workloads and heavy multitasking.

Sustained Power Delivery

A 14+1+1+2 phase design uses 80A DrMOS power stages, ProCool connectors, a 6-layer PCB, alloy chokes and durable capacitors to maintain stable voltage under continuous load. Large VRM heatsinks, dedicated M.2 and PCH heatsinks, plus hybrid fan headers managed by Fan Xpert 4 and AI Cooling II keep temperatures controlled during long rendering or compute sessions. The 125W processor stays fed without throttling, ensuring consistent output over hours rather than minutes.

Connectivity & Build

The rear I/O includes a Thunderbolt 4 USB Type-C port, one USB 10Gbps Type-A, two USB 5Gbps Type-A, four USB 2.0 Type-A, DisplayPort, HDMI, 2.5Gb Ethernet and Wi-Fi 7 with the ASUS WiFi Q-Antenna. Onboard headers add a USB 10Gbps Type-C connector, four USB 5Gbps and four USB 2.0 ports. Storage options cover one PCIe 5.0 M.2 slot with heatsink, three PCIe 4.0 M.2 slots, four SATA 6Gb/s ports and RAID 0/1/5/10 support. Audio uses a Realtek 7.1 codec with shielding and 24-bit/192 kHz playback.

Questions about this item

How hot or loud does the 14+1+1+2 80A DrMOS VRM get under sustained 125W load?

The board uses large VRM heatsinks, a 6-layer PCB and AI Cooling II via Fan Xpert 4 to manage heat from the 14+1+1+2 80A DrMOS stages during prolonged 125W CPU operation.

Which DDR5 memory kit speed should I have ready for the 8666+ MT/s XMP profile?

You need a DDR5 CUDIMM kit rated for 8666+ MT/s; the four 288-pin slots run dual-channel up to 256GB and support Intel XMP and ASUS AEMP III profiles.

Will my existing PCIe 4.0 GPU and SATA SSDs work without bottlenecks on the Z890 chipset lanes?

Yes — the chipset provides two PCIe 4.0 x16 slots wired x4, one PCIe 4.0 x16 slot wired x1, and four SATA 6Gb/s ports for legacy drives.
