Custom Ryzen 7 9800X3D Workstation

This Adamant Custom tower pairs an 8-core AMD Ryzen 7 9800X3D processor with a GeForce RTX 5090 graphics card. It ships with 192GB DDR5 memory and 8TB NVMe storage across two 4TB Samsung 990 PRO drives. Windows 11 Pro is pre-installed on a liquid-cooled platform built for modelling, rendering and AI learning workloads.

Suited For Modelling And AI Tasks

The 192GB DDR5 capacity and dual 4TB NVMe drives serve professionals who need large datasets in memory and fast scratch space. Buyers who need more than 192GB RAM or additional internal drive bays beyond the four provided should consider a different chassis. The system targets workstation workflows rather than compact living-room builds.

Deciding Specification Is 192GB DDR5 Memory

The motherboard supports four slots with a 192GB maximum, and this unit populates every slot at that limit. No further memory upgrades are possible without replacing modules. Confirm that your applications benefit from this capacity before purchase.

Questions about this item

How do I install the 240mm AIO liquid cooler and what step is often missed?

Mount the radiator to the case using the included brackets, connect the pump header to the CPU_FAN connector on the TUF X870-PLUS motherboard, then attach the 140mm fans; the step often missed is plugging the pump tach cable into the dedicated AIO_PUMP header so the BIOS can monitor pump speed.

What maintenance or replacement will the 240mm AIO liquid cooler need later?

The sealed 240mm Quiet Edition loop requires no fluid top-up; plan to replace the thermal paste between the cold plate and the Ryzen 7 9800X3D every two to three years and clean dust from the 140mm radiator fans annually.

What limit appears first during sustained heavy workloads on this system?

The 1200W 80 PLUS Gold PSU delivers up to 1200 watts; under continuous full-load the combined draw of the 9800X3D and RTX 5090 approaches that ceiling, so power headroom becomes the first limiting factor.
