Custom Workstation with RTX 5090

The Adamant Custom desktop is a new tower system built for professionals and enthusiasts who need maximum single-thread and multi-thread throughput. It pairs a 24-core Intel Core i9-14900K with a 360 mm liquid cooler, 32 GB of DDR5 memory and a GeForce RTX 5090 carrying 32 GB of VRAM. Windows 11 Pro is pre-installed on a 1 TB Samsung 990 PRO NVMe drive.

Who this suits and who it does not

Content creators, 3D artists and AI researchers gain the 24-core CPU, high VRAM GPU and fast NVMe storage for rendering, simulation and model training. Buyers who only play at 1080p or need a compact chassis should look at smaller air-cooled builds with mid-range graphics cards.

The specification that decides fit

The GeForce RTX 5090 with 32 GB VRAM determines whether this system matches the workload; workloads that require larger frame buffers for 8K textures, large language models or complex scenes need this capacity, while lighter tasks do not.

Questions about this item

How much noise and heat does the 360 mm liquid cooler and 140 mm PSU fan produce when the i9-14900K and RTX 5090 run all day?

The 360 mm Quiet Edition AIO and Thermaltake 1200 W Gold PSU with its 140 mm low-noise fan are designed to handle the 24-core CPU and RTX 5090 under sustained load while keeping acoustic levels low.

Which display cable and monitor inputs do I need to use the RTX 5090's video outputs?

The RTX 5090 provides modern display connectors; you will need a monitor with compatible HDMI or DisplayPort inputs and the matching cable to get a picture.

Can I add more DDR5 modules or M.2 NVMe drives later using the Z790 TUF motherboard's spare slots?

Yes, the board has four DDR5 slots (32 GB installed) supporting up to 192 GB total, plus four M.2 connectors for additional NVMe storage.
