Adamant Custom 24-Core i9-14900K 128GB RTX 5090 Gaming PC

Adamant Custom 24-Core i9 Workstation

This Adamant Custom tower is a 2026 gaming desktop built around a 24-core Intel Core i9-14900K processor and an Nvidia GeForce RTX 5090 graphics card with 32GB VRAM. It runs Windows 11 Pro on 128GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe SSD. A 360mm liquid cooler and a 1200W 80 PLUS Gold PSU support the high-end components inside a Cooler Master HAF 500 case.

Suits 4K gaming and AI modelling.

The system targets users who need 24 cores, 32 threads and a 5090 GPU for 4K gaming, rendering, modelling or AI learning workloads. Buyers who want more storage than 1TB, a smaller chassis, or a lower power draw should look at other configurations. The four memory slots allow expansion up to 192GB if workloads grow beyond the fitted 128GB.

Deciding spec: RTX 5090 32GB GPU

The single specification that decides fit is the Nvidia GeForce RTX 5090 with 32GB of video memory. This card determines whether the system can handle the target 4K gaming, heavy rendering or large-model AI tasks. If the workload does not require that level of GPU memory and compute, a different graphics tier would be more appropriate.
