24-Core Workstation for AI and Rendering

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with 128GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. The configuration targets professionals running AI learning workloads, complex 3D modelling and high-resolution video editing. Windows 11 Pro is pre-installed on the 4TB NVMe boot drive.

32GB RTX 5090 GPU for Large Model Workloads

The installed GeForce RTX 5090 provides 32GB of video memory, the single specification that determines whether this system can hold large neural networks or massive scene files in VRAM. Buyers who need more GPU memory for bigger models cannot meet that requirement with this card. A 10TB hard drive adds bulk storage for project archives.

360mm Liquid Cooling with 1200W Gold Power Supply

A 360mm quiet-edition AIO liquid cooler handles the CPU thermal load while a Thermaltake Toughpower 1200W 80 PLUS Gold unit delivers power with over-voltage, under-voltage, over-power and short-circuit protection. Front 140mm PWM fans and a tempered-glass side panel complete the mid-tower airflow design.

Questions about this item

What does the 24-core 3.7 GHz CPU mean for actual rendering or AI workloads?

The 24-core Intel Core Ultra 9 285K runs at a 3.7 GHz base and can boost to 5.70 GHz with 36 MB L3 cache, giving strong multi-thread throughput for rendering, modelling and AI learning tasks.

How fast is the 4 TB Samsung 990 PRO over the PCIe 4.0 x4 link?

The drive is rated for sequential reads up to 7450 MB/s and writes up to 6900 MB/s, so the PCIe 4.0 x4 interface caps real-world transfer at those speeds.

Will the 360 mm liquid cooler and RTX 5090 fit in the mid-tower case?

The case measures 447 x 215 x 469 mm and includes a 360 mm AIO cooler plus front 140 mm fans, providing clearance for the RTX 5090 and liquid cooling radiator.
