Built for intensive rendering and AI workloads

This desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU and 64GB DDR5 memory. A 4TB Samsung 990 PRO NVMe drive provides fast local storage for large project files. The system targets professionals running 3D modelling, video editing or machine-learning training who need sustained multi-threaded performance in a single workstation.

360mm liquid cooler and 1200W Gold PSU manage heat

A 360mm quiet-edition AIO handles the CPU while the Thermaltake Toughpower 1200W 80 PLUS Gold unit supplies stable power with a 140mm low-noise fan. Case airflow uses two front 140mm PWM fans behind a tempered-glass panel. The motherboard integrates 2.5Gbps LAN and Wi-Fi 7 2x2 for high-throughput network transfers during dataset moves.

Replaces a multi-node render farm

Consolidating GPU compute, high-capacity memory and fast NVMe into one mid-tower removes the latency and management overhead of distributed nodes. The jump is worthwhile when single-frame render times or model-training iterations must drop below what a dual-socket or previous-generation single-socket box can deliver. Builders who need more than 192GB RAM or a second RTX 5090 should look at a larger chassis and higher-wattage platform.

Questions about this item

How is the 360mm liquid cooler mounted, and which step do builders often skip?

The 360mm AIO radiator screws into the top of the mid-tower case; the step many miss is connecting the pump header and the 140 mm fan PWM cables to the Z890M AORUS board before closing the panel.

What maintenance or replacement will the liquid cooler need later?

The sealed 360 mm AIO is maintenance‑free for its service life; if the pump ever fails the whole unit is swapped, no refill or tube work required.

What limit appears first when the RTX 5090 32GB and Core Ultra 9 285K run flat‑out for hours?

The 1200 W 80 PLUS Gold PSU caps total draw, so sustained combined GPU and CPU load will hit the power‑supply ceiling before thermals or memory bandwidth do.
