Workstation for AI and rendering

This tower desktop combines a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card and 192GB of DDR5 memory. Two 4TB Samsung 990 PRO SSDs provide 8TB of NVMe storage. A 360mm liquid cooler and a 1200W 80 PLUS Gold power supply support sustained heavy workloads.

Suited for local model training and 3D pipelines

The configuration targets developers running large language models, video editors working with 8K timelines and engineers simulating complex scenes. Buyers who need more than 192GB of system memory or who require multiple GPU slots for scaling should look at a different platform.

192GB DDR5 maximum memory decides fit

The motherboard supports a total of 192GB across four slots and this build already populates that limit. If your dataset or virtual-machine fleet demands more RAM, this chassis cannot accept additional modules.

Questions about this item

What clearance does the 360 mm AIO radiator need inside the Antec P20 case?

The 360 mm radiator mounts in the top or front of the 469 mm deep case; verify the 220 mm width and 490 mm height allow the 120 mm fans and tubing without hitting the motherboard heatsinks.

Which power cables from the Thermaltake Toughpower 1200W unit must be connected to the RTX 5090?

Attach the dedicated PCIe 12VHPWR cable directly to the GPU; do not use daisy-chained or adapter leads, and ensure the PSU switch is on before first boot.

How many M.2 slots remain free after the two Samsung 990 PRO 4 TB drives are installed?

The Z790 TUF board provides four M.2 connectors; two are occupied by the factory SSDs, leaving two open for future NVMe expansion.
