Built for 24-Core AI and Render Workloads

This desktop pairs a 24-core Intel Core Ultra 9 285K processor with 64GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card carrying 32GB of VRAM. A 1TB Samsung 990 PRO NVMe drive and a 1200W 80 PLUS Gold power supply complete a platform aimed at local model training, 3D rendering and high-resolution video editing. Liquid cooling keeps the CPU stable under sustained multi-threaded loads.

Suits Single-Box Studios Needing Maximum VRAM

Creators who want one system for GPU-accelerated AI inference, complex simulation and 8K timeline playback will match the 32GB frame buffer and unified DDR5 bandwidth. Buyers who need more than 64GB of system memory or additional internal drive bays beyond the two 3.5-inch and two 2.5-inch slots should look at a chassis with greater expandability.

32GB GPU VRAM Decides Fit for Large Models

The RTX 5090’s 32GB of video memory is the single specification that determines whether this workstation can hold your largest models and textures entirely on the card. If your workflow fits within that VRAM ceiling the system delivers full GPU acceleration; if it exceeds it you will need a different GPU configuration.

Questions about this item

What comes in the box and what do I need to buy separately?

The system ships fully assembled with the Core Ultra 9 285K, 64 GB DDR5, 1 TB Samsung 990 PRO NVMe, RTX 5090 32 GB, 1200 W 80 PLUS Gold PSU, 360 mm liquid cooler, Windows 11 Pro, Wi-Fi 7 and Bluetooth5.4. Only a monitor, keyboard and mouse are required to start.

Which memory capacity should I choose for rendering and AI workloads?

The board has four DDR5 slots and supports up to 192 GB. The installed 64 GB handles most creative tasks; add matching modules later if projects regularly exceed that ceiling.

What does the 5.70 GHz boost clock mean once the PC is running real workloads?

The 24-core CPU can reach 5.70 GHz on active cores while the 360 mm liquid cooler keeps temperatures stable, so sustained all-core speeds stay high during long renders or model training.
