Built for heavy AI and render workloads

This desktop pairs a 20-core Intel Core Ultra 7 265K with an Nvidia GeForce RTX 5090 32GB GPU and 128GB of DDR5 memory. The combination targets professionals running large language models, complex simulations or multi-application creative pipelines. Windows 11 Pro ships pre-installed on the 1TB Samsung 990 PRO NVMe drive.

Verify PSU headroom and case clearance

The system draws power through a Thermaltake Toughpower 1000W 80 PLUS Gold unit with a 140mm fan. Builders adding extra drives or expansion cards should confirm the remaining wattage budget before ordering. The Corsair 4000D chassis measures 490mm deep by 239mm wide by 486mm high and offers two 3.5in and two 2.5in internal bays.

Liquid loop keeps clocks steady over long sessions

A 240mm quiet-edition AIO circulates coolant across the CPU while the GPU relies on its own vapour-chamber cooler. Under sustained multi-hour loads the coolant temperature stabilises, allowing the processor to hold its 5.50GHz boost without thermal throttling. The 10TB hard drive with 256MB cache provides bulk storage that does not add heat to the primary loop.

Questions about this item

What comes in the box with this Adamant Custom PC and what must I buy separately?

Should I choose the 128GB DDR5 configuration or upgrade toward the 192GB maximum?

The system ships with 128GB DDR5 across four slots. The board supports up to 192GB, so only select a larger kit if your rendering, modelling or AI workloads regularly exceed 128GB.

What does the RTX 5090 32GB actually deliver inside this workstation?

The RTX 5090 32GB provides 32GB of video memory for 3D rendering, large-model AI training and high-resolution gaming, driven by the 20-core CPU and 128GB DDR5 system memory.
