Ready-to-run workstation

This desktop ships with Windows 11 Pro installed and a liquid-cooled 14-core Intel Core Ultra 5 245K processor. The Z890 motherboard provides Thunderbolt 4, Wi-Fi 7 and Bluetooth 5.4 connectivity. It targets creators and engineers who need a quiet, high-memory system without assembly.

192 GB DDR5 ceiling

Four slots are populated to the board’s 192 GB maximum, so no further memory upgrades are possible. The CPU reaches 5.20 GHz boost with 24 MB L3 cache. Buyers who anticipate larger datasets or virtualisation clusters will need a platform that supports more RAM.

4 TB NVMe and 32 GB GPU

A Samsung 990 PRO delivers up to 7450 MB/s read and 6900 MB/s write for active projects. The RTX 5090 with 32 GB VRAM handles 8K timelines and large batch renders. Storage-bound workflows exceeding 4 TB or multi-GPU compute tasks require external expansion.
