24-Core Workstation for AI and Rendering

This desktop pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 32GB GPU and 192GB of DDR5 memory. A 4TB Samsung 990 PRO NVMe drive provides primary storage. The system ships with Windows 11 Pro installed and uses a 360mm liquid cooler on the CPU.

Suited for local AI training and heavy 3D work

The 192GB memory ceiling and 24-core processor handle large datasets and complex scenes. Builders who need more than 4TB of high-speed storage or a second graphics card should look elsewhere, as the board offers four M.2 slots but the chassis limits additional drive bays.

Bundled cooler and power supply enable sustained

The included 360mm quiet-edition AIO keeps the 24-core CPU at working temperatures during long renders. A 1200W 80 PLUS Gold unit delivers stable power to the RTX 5090 and all other components. Wi-Fi 6 and Bluetooth 5.2 are integrated on the Z790 TUF motherboard.

Questions about this item

Does the Z790 TUF motherboard need a separate CPU power cable from the 1200W PSU to run the i9-14900K?

Yes, the Thermaltake Toughpower 1200W 80 PLUS Gold unit includes the required 8-pin EPS connectors for the LGA 1700 socket and the 24-core i9-14900K.

Can I keep my SATA 6Gb/s hard drives and plug them into the four SATA ports on the Z790 TUF board?

The motherboard provides four SATA 6Gb/s connectors, so existing 2.5-inch or 3.5-inch SATA drives will work alongside the 4TB Samsung 990 PRO NVMe boot drive.

How do I verify the RTX 5090 32GB is running at PCIe 4.0 x4 speed after Windows 11 Pro boots?

Open GPU-Z or Task Manager Performance tab; the Bus Interface should read PCIe 4.0 x4 and the dedicated GPU memory will show 32GB.
