Adamant Custom Ryzen 9 9900X3D Workstation

This gaming desktop PC ships with a 12-core AMD Ryzen 9 9900X3D processor reaching 5.50 GHz boost, 128GB DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. Liquid cooling and a 1200W 80 PLUS Gold power supply support sustained workloads in a Corsair 4000D chassis. Windows 11 Pro is pre-installed for immediate deployment.

Suits AI training, rendering and modelling.

The 128GB DDR5 capacity and RTX 5090 32GB VRAM handle large datasets, complex 3D scenes and intensive inference tasks. Builders who need only mainstream gaming performance or smaller memory footprints should look at systems with lower specifications. The four memory slots allow expansion up to 192 GB if requirements grow.

128GB DDR5 and RTX 5090 32GB define the capability

The combination of 128GB DDR5 system memory and 32GB GPU memory sets the practical limit for model size, texture resolution and concurrent application count. Storage comprises a 1TB Samsung 990 PRO NVMe SSD rated at 7450 MB/s read and 6900 MB/s write, plus a 10TB HDD with 256MB cache for bulk data.

Questions about this item

What case dimensions and motherboard form factor does the Corsair 4000D chassis support?

The Corsair 4000D measures 490 x 239 x 486 mm and fits the PRIME X870-P ATX motherboard with standard ATX mounting points.

How is the 240 mm AIO liquid cooler mounted to the AM5 socket, and what step is often missed?

The 240 mm AIO uses the AM5 backplate and four spring screws; the step often missed is removing the plastic cover from the cold-plate before securing the pump block.

Which storage drives occupy the internal bays and M.2 slots, and what will need replacement first?

The 1 TB Samsung 990 PRO occupies one M.2 slot and the 10 TB HDD fills a 3.5" bay; the HDD is the mechanical component most likely to need replacement first.
