Built for AI and heavy rendering

This tower workstation ships with a 24-core Intel Core i9-14900K and 192 GB of DDR5 memory. It targets creators who train models, edit 8K timelines or run large simulations locally. The liquid-cooled CPU and RTX 5090 32 GB GPU keep thermals stable during sustained loads. Buyers who only game or browse will not use this headroom.

The spec that decides fit

The 192 GB DDR5 kit fills every slot on the Z790 board, so no further memory upgrades are possible. If your workload needs more than 192 GB you must choose a different platform. The 1 TB Samsung 990 PRO NVMe drive delivers 7450 MB/s reads and 6900 MB/s writes for fast project loading. Storage expansion uses the remaining M.2 or SATA ports.

Installation notes

The system arrives assembled with Windows 11 Pro installed and drivers configured. The 360 mm AIO cooler is pre-mounted but check pump orientation before first boot. The Cooler Master HAF 500 case uses 200 mm front fans and a 120 mm rear fan for airflow. Verify the 1200 W PSU cables are fully seated; loose GPU power leads are the most common cause of no-post on high-wattage builds.
