Custom workstation for modelling and AI learning

This Adamant Custom desktop combines a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It ships with Windows 11 Pro and 64 GB of DDR5 memory. The system targets professionals who need compute power for rendering, simulation and machine-learning workloads.

32 GB GPU memory for large model training

The RTX 5090 provides 32 GB of video memory, the single specification that determines whether this machine can hold large neural networks or high-resolution textures without off-loading to system RAM. Buyers who need more VRAM for bigger batches cannot meet that requirement with this configuration.

Liquid cooling sustains 5.50 GHz boost clocks

A 240 mm quiet-edition AIO keeps the CPU at its 5.50 GHz maximum boost under prolonged compile or render jobs. The 1200 W 80 PLUS Gold power supply delivers stable current for the GPU during extended training runs. Thermal throttling is minimised so throughput stays consistent over hours.

Questions about this item

What does the 5.50 GHz boost mean once the Ryzen 9 9900X3D is inside the machine?

The 12-core CPU can reach 5.50 GHz for short bursts, giving faster single-thread response in games and snappier UI while the 240 mm liquid cooler keeps temperatures in check.

What does the PCI Express x16 graphics interface cap in practice for the RTX 5090?

The x16 slot delivers full bandwidth to the RTX 5090, so the 32 GB GPU runs without a bottleneck for 4K gaming and AI workloads.

What does the Corsair 4000D case need to fit the 240 mm liquid cooler and the RTX 5090?

The 490 mm deep chassis has room for a 240 mm radiator at the front or top and clears long graphics cards, so both the AIO and the RTX 5090 install without modification.
