Ready-to-run workstation

This Adamant Custom desktop pairs an 8-core AMD Ryzen 7 9800X3D processor with a GeForce RTX 5090 graphics card, 64 GB DDR5 memory and a 4 TB NVMe SSD. Windows 11 Pro is pre-installed on a mid-tower chassis cooled by a 240 mm liquid loop. The system targets professionals who need modelling, rendering or AI learning performance in a single package.

Best fit and limits

Buyers who want a complete, liquid-cooled workstation for modelling, video editing or AI learning will find the CPU, GPU and memory balance suited to those workloads. Builders who need more than 64 GB of memory should look elsewhere, as the board supports up to 192 GB but this unit ships with half that amount. Users requiring additional internal drive bays beyond the two 3.5-inch and two 2.5-inch slots will also need a different chassis.

Deciding specification

The GeForce RTX 5090 with 32 GB of video memory is the single component that determines whether this build matches the workload, because modelling, rendering and AI learning tasks that exceed lesser GPU memory capacities will only run comfortably on this card.

Questions about this item

Will the 240 mm AIO liquid cooler need coolant top-ups or pump replacement?

The 240 mm Quiet Edition AIO is a sealed loop; no coolant top-ups are required. Pump life is typically several years; if flow drops or noise rises, the whole unit is swapped rather than serviced.

What thermal limit will the Ryzen 7 9800X3D hit first during long rendering sessions?

The CPU targets a 5.20 GHz boost ceiling; under sustained all-core load it will throttle to stay within its thermal envelope before the 240 mm AIO reaches saturation.

How loud and hot does the system get when the RTX 5090 and CPU run all day?

The 1200 W 80 PLUS Gold PSU and 140 mm fan keep noise low; liquid cooling moves CPU heat directly to the radiator, while the GPU’s own fans exhaust into the Antec P20’s front-to-rear airflow.
