Custom 24-Core Workstation for AI and Rendering

This Adamant Custom desktop pairs an Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU. It ships with 64GB DDR5 memory, a 4TB NVMe SSD and a 10TB HDD. The system targets professionals who need high compute throughput for rendering, modelling and AI learning workloads.

Suits GPU-heavy pipelines.

The single RTX 5090 delivers 32GB VRAM for large model inference and 3D scenes. Buyers who need a second card for parallel workloads or more than 32GB VRAM per GPU should look at a different platform. The mid-tower chassis and 1200W PSU support this configuration only.

24-core CPU with 5.70 GHz boost drives

The Intel Core Ultra 9 285K reaches 5.70 GHz max turbo across its 24 cores. That peak frequency decides how fast the system finishes serial compile, simulation or CAD steps before the GPU takes over.

Questions about this item

Will the 1200W PSU and 360mm liquid cooler handle the RTX 5090 and Core Ultra 9 285K together?

The system ships with a Thermaltake Toughpower 1200W 80 PLUS Gold unit and a 360mm Quiet Edition AIO cooler, both chosen for the 24-core CPU and 32GB GPU.

Can the Z890 motherboard still run my older SATA SSDs and USB 2.0 peripherals?

Yes, the board provides four SATA 6Gb/s ports and four USB 2.0 rear ports plus four more via mid-board headers.

How do I verify the Samsung 990 PRO is delivering its rated 7450 MB/s read speed?

Run CrystalDiskMark or a similar NVMe benchmark; sequential read should approach 7450 MB/s and write near 6900 MB/s on the PCIe 4.0 x4 link.
