AI-Ready Platform

The ASUS ROG MAXIMUS Z890 EXTREME motherboard paired with an Intel Core Ultra 5 245K processor targets builders who want an advanced AI PC foundation. The LGA 1851 socket supports Intel Core Ultra Series 2 chips and the board carries the Z890 chipset with a 24+2+1+2 stage power design. Four DDR5 slots accept up to 256 GB running at 9200 MT/s via XMP or AEMP III. Connectivity includes WiFi7, Bluetooth 5.4, 2.5 GbE and 10 GbE LAN, two Thunderbolt 5 ports and multiple USB 20 Gbps and 10 Gbps ports.

Sustained Load Behaviour

The 24+2+1+2 stage VRM delivers stable current to the 125 W Arrow Lake CPU during extended workloads. AI Overclocking and NPU Boost tune frequencies automatically while AI Cooling II adjusts fan curves in real time. The U-shaped heatpipe links massive heatsinks across the I/O cover and power stages using high-conductivity pads. A 3D vapour-chamber heatsink covers the primary PCIe 5.0 M.2 slot to keep storage temperatures in check under continuous throughput.

Thermals Noise Power

The integrated thermal solution spreads heat from the VRM and chipset across a large surface area, allowing lower fan speeds at typical desktop loads. AI Networking II manages traffic to reduce unnecessary controller activity. The 125 W processor base power sets a clear envelope for cooling planning. Onboard SupremeFX 7.1 audio with the ALC4082 codec isolates analogue sections from digital noise for cleaner output during quiet operation.

Questions about this item

How loud or hot does the 24+2+1+2 stage VRM and 125 W Ultra 5 245K get when the system runs all day?

The board uses massive heatsinks integrated with the I/O cover, a U-shaped heatpipe, high-conductivity thermal pads and a 3D VC M.2 heatsink to dissipate heat from the 24+2+1+2 power stages and the 125 W processor. AI Cooling II adjusts fan curves automatically to keep noise low under sustained loads.

Which DDR5 memory kit must I already own for the 4×288-pin slots to reach the advertised 9200+ MT/s?

You need a DDR5 CUDIMM kit rated for 9200+ MT/s (OC) that supports Intel XMP or ASUS AEMP III; the four slots accept up to 256 GB total in dual-channel mode.

Will my existing PCIe 4.0 graphics card and SATA SSDs work without bandwidth loss on the PCIe 5.0 x16 and SATA 6 Gb/s ports?

Yes. The primary PCIe 5.0 x16 slot is backward compatible with PCIe 4.0 cards, and the four SATA 6 Gb/s ports run at full speed regardless of M.2 configuration.
