Purpose-built workstation

The Adamant Custom desktop combines a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5090 32GB graphics card. It ships with 64GB of DDR5 memory and a 2TB Samsung 990 PRO NVMe drive. Windows 11 Pro is pre-installed on a liquid-cooled platform designed for rendering, modelling and AI learning workloads.

Who this suits

Creators and engineers who need high single-thread frequency up to 5.70 GHz, 36 MB of L3 cache and 32GB of GPU memory for large datasets will benefit immediately. Buyers who require more than 64GB of system memory out of the box or who need multiple GPU slots for parallel compute should look at a different configuration.

Deciding specification

The single specification that decides fit is the GeForce RTX 5090 with 32GB of video memory. That frame-buffer size determines whether the system can hold your working set in GPU memory without paging to system RAM.

Questions about this item

What comes in the box and what must I buy separately?

The system ships fully assembled with the Intel Core Ultra 9 285K, 64GB DDR5, 2TB Samsung 990 PRO NVMe, GeForce RTX 5090 32GB, 1200W 80 PLUS Gold PSU, 360mm liquid cooler, Windows 11 Pro, Wi‑Fi 7 and Bluetooth5.4. Only a monitor, keyboard and mouse are needed.

Which memory or storage version should I choose for this build?

The board has four DDR5 slots supporting up to 192GB total; the installed 64GB kit leaves two slots free for matching DDR5 modules. Storage uses a 2TB PCIe 4.0 NVMe drive; two additional M.2 slots and two 2.5″/3.5″ bays are open for extra NVMe or SATA drives.

What does the 24‑core 3.7GHz CPU rating mean in daily work?

The 24‑core Ultra 9 285K runs at a 3.7GHz base with a 5.70GHz max turbo and 36MB L3 cache, so multi‑threaded rendering, modelling and AI training workloads scale across all cores while single‑thread bursts hit the higher clock for responsive OS and app performance.
