Ready for Advanced AI PCs

This combo pairs an ASUS ROG STRIX Z890-A GAMING WIFI S motherboard with an Intel Core Ultra 5 245K processor. The board uses the Intel Z890 chipset and an LGA 1851 socket built for Intel Core Ultra Series 2 chips. It targets builders who want AI-ready performance and high-speed connectivity in a single package.

16+2+1+2 power stages

The voltage regulator module delivers 16 Vcore stages at 90 A, two VCCGT stages at 90 A, one VCCSA stage at 90 A and two VNN stages at 80 A. ProCool II connectors, MicroFine alloy chokes and premium metallic capacitors back the design. This specification decides whether the board can sustain heavy all-core loads without throttling.

192 GB DDR5 across four slots

Four 288-pin slots support dual-channel DDR5 up to 192 GB with XMP profiles and speeds up to 9066 MT/s when overclocked. DIMM Fit, DIMM Flex and AEMP III simplify tuning. Five M.2 slots — one PCIe 5.0 x4 and four PCIe 4.0 x4 — plus four SATA 6 Gb/s ports give ample storage headroom. Thunderbolt 4, WiFi 7, Bluetooth 5.4 and 2.5 Gbps LAN complete the I/O.

Questions about this item

What does the 125 W base power of the Core Ultra 5 245K mean for my cooling choice?

The processor has a 125 W base power rating and no cooler is included, so you will need a capable air or liquid cooler rated for at least that thermal design power to keep temperatures in check under sustained loads.

How fast can the Thunderbolt 4 ports on the back I/O actually move data?

Each Thunderbolt 4 port delivers up to 40 Gbps of bandwidth, shared with DisplayPort video and up to 30 W of power delivery on the USB Type-C connector that supports fast charging.

Will the massive heatsinks and L-shaped heatpipe on this Z890 board fit inside a standard ATX case?

The board follows the ATX form factor, so it mounts in any ATX-compatible chassis, but the large VRM heatsinks and integrated I/O cover may sit close to the side panel — verify your case’s CPU-cooler clearance and motherboard-to-side-panel depth before buying.
