Ready-to-run AI workstation

The 128 GB DDR5 memory and 1 TB Samsung 990 PRO NVMe drive provide capacity for large models and fast dataset loading. Integrated graphics drive HDMI and DisplayPort outputs for immediate display connectivity.

Platform interface limits

The Z890 motherboard offers Thunderbolt 4, USB 20 Gbps and USB 10 Gbps ports alongside four SATA 6 Gb/s and four M.2 connectors. Network access comes from Intel 2.5 Gb Ethernet plus Wi-Fi 7 2x2 and Bluetooth 5.4. Four DDR5 slots support up to 192 GB total, leaving room for future expansion beyond the fitted 128 GB.

Pre-order compatibility checks

Verify that your monitors accept HDMI or DisplayPort signals from integrated graphics, as no discrete GPU is installed. Confirm the 490 x 239 x 486 mm Corsair 4000D case fits your desk space and that the 750 W 80 PLUS Bronze PSU meets any future add-in card power needs. Ensure your workflow can operate within integrated graphics performance.

Questions about this item

Should I choose the 128GB DDR5 configuration or the maximum 192GB supported by the motherboard?

The system ships with 128GB DDR5 across four slots. The Z890 board supports up to 192GB, so you can add more later if workloads demand it.

What does the 5.20GHz turbo on the 14-core Core Ultra 5 245K deliver in daily use?

The 14-core CPU reaches 5.20GHz for burst workloads, while the 240mm liquid cooler keeps sustained clocks high during long renders or compiles.

How fast is the Samsung 990 PRO 1TB over the PCIe 4.0x4 link?

The NVMe drive is rated for 7450MB/s read and 6900MB/s write on the PCIe 4.0x4 interface, so large game loads and project files open quickly.
