24-Core Intel Core Ultra 9 Workstation

This desktop is built around a 24-core Intel Core Ultra 9 285K processor and a GeForce RTX 5090 graphics card with 32GB of video memory. It targets professionals running rendering, editing, modelling and AI learning workloads that benefit from high core counts and large GPU frame buffers. The system ships with Windows 11 Pro installed and includes a 360mm liquid cooler for sustained CPU performance.

128GB DDR5 capacity with 192GB ceiling

Four memory slots hold 128GB of DDR5 today and support a maximum of 192GB for future expansion. The 1TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/sec and write speeds up to 6900 MB/sec, providing fast scratch space for active projects. Storage headroom ends at the single M.2 slot populated; builders who need more capacity must add SATA drives or additional M.2 modules themselves.

Replaces dual-GPU render nodes

The combination of a 1200W 80 PLUS Gold power supply, 2.5Gbps Ethernet and Wi-Fi 7 connectivity consolidates what previously required separate render boxes and network upgrades. The jump is worth it when a single 32GB GPU covers the entire scene memory requirement and the 24-core CPU keeps feed rates high. Buyers who need multi-GPU scaling or more than 1TB of high-speed NVMe storage should look elsewhere.
