Adamant Custom i9-14900K RTX 5090 192GB 8TB Gaming PC

24-Core Workstation for AI and Rendering

This system pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 and 192GB of DDR5 memory. It targets professionals running local AI inference, complex 3D rendering or heavy modelling workloads that demand high GPU memory and sustained multi-threaded CPU performance. The 8TB NVMe array provides fast local storage for large datasets and project files.

Check Power, Space and Motherboard Limits

The chassis measures 490 x 239 x 486 mm and requires a 1200W 80 PLUS Gold supply already installed. Verify your mains circuit can deliver adequate current for the 1200W unit and that the 360 mm liquid cooler has clearance in your intended location. The Z790 PRIME motherboard offers four memory slots, all populated to reach the 192 GB maximum, so no further RAM upgrades are possible without replacing modules.

Sustained Load Behaviour with Liquid Cooling

Under continuous compute load the 360 mm quiet-edition liquid cooler keeps the 24-core processor near its 6.00 GHz boost ceiling without thermal throttling. The Thermaltake 1200W Gold unit maintains stable voltage rails during prolonged GPU and CPU utilisation, while the 140 mm PSU fan runs at low speed. Samsung 990 PRO drives sustain sequential reads up to 7450 MB/s and writes up to 6900 MB/s during extended transfer sessions.
