Workstation for AI and rendering

This desktop combines a twelve-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. It targets professionals who run local AI training, 3D modelling or video editing workloads that demand both high core counts and large VRAM. The system ships with Windows 11 Pro installed and includes a 240mm liquid cooler for the CPU.

32GB VRAM on RTX 5090

The graphics card provides 32GB of video memory, which is the single figure that determines whether large models or 8K textures fit entirely on the GPU. If your workflow exceeds that capacity you will see paging to system memory and a sharp performance drop. The card connects through a PCI Express x16 slot on the PRIME X870-P motherboard.

Liquid cooling under sustained load

A 240mm quiet-edition AIO cooler handles the CPU heat output during long rendering or training sessions. The Thermaltake Toughpower 1200W 80 PLUS Gold power supply delivers stable current with Japanese main capacitors and a 140mm low-noise fan. The Corsair 4000D case provides airflow through front and top mounts to keep internal temperatures steady over hours of continuous work.

Questions sur cet article

How does the 12-core Ryzen 9 9900X3D perform inside this chassis with liquid cooling?

The 12-core 24-thread CPU runs at 4.4 GHz base and can boost to 5.50 GHz with 128 MB L3 cache, sustained by a 240 mm AIO liquid cooler in the Corsair 4000D case.

What bandwidth does the PCI Express x16 slot provide for the RTX 5090?

The PRIME X870-P motherboard wires the GPU to a full PCI Express x16 link, giving the RTX 5090 32 GB card the maximum lane width the platform supports.

Will the 490 mm deep Corsair 4000D case fit on my desk and accept the 240 mm radiator?

The case measures 490 mm deep, 239 mm wide and 486 mm high, with internal bays for two 3.5-inch and two 2.5-inch drives and a top mount for the 240 mm AIO radiator.
