24-Core Ultra 9 Workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5090 graphics card. It targets professionals who need high single-thread speed and massive parallel compute for rendering, modelling and AI learning workloads. Liquid cooling and a 1200W 80 PLUS Gold power supply keep the platform stable under sustained load.

128GB DDR5 and 14TB Storage

Four DDR5 slots hold 128GB today and support up to 192GB when larger modules arrive. A 4TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for active projects. The 10TB hard drive adds bulk capacity for archives, though its mechanical latency limits random-access speed.

RTX 5090 32GB VRAM Decides Fit

The graphics card provides 32GB of video memory, which determines whether large models, high-resolution textures or multi-GPU frameworks fit entirely on the accelerator. If a workflow needs more VRAM than 32GB, this system cannot satisfy it. Buyers who need greater GPU memory must look elsewhere.

Questions about this item

Will the 128GB DDR5 memory in this system run alongside any DDR5 sticks I already own?

The board has four DDR5 slots with a 192GB maximum; you can add compatible DDR5 modules to the two free slots, but mixing speeds or timings may force all memory to run at the lowest common settings.

How can I verify the RTX 5090 is delivering its 32GB frame buffer and 5.70GHz CPU boost after assembly?

Open Task Manager's Performance tab to confirm 32GB dedicated GPU memory and watch the CPU frequency hit 5.70GHz under a heavy all-core load such as Cinebench.

Which items ship inside the Ceres 300 case and what must I source separately?

The PC arrives fully assembled with the Ultra 9 285K, 360mm liquid cooler, 128GB DDR5, 4TB Samsung 990 PRO SSD, 10TB HDD, RTX 5090, 1200W Gold PSU, Windows 11 Pro, Wi-Fi 7 and Bluetooth5.4; only a monitor, keyboard and mouse are needed to start.
