24-Core Intel Ultra 9 Workstation

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. It targets professionals who need heavy multi-threaded compute for rendering, modelling or AI learning workloads. Windows 11 Pro is installed and the system is described as AI ready.

Check Motherboard And Power Compatibility

The CPU uses an LGA 1851 socket on a Z890 chipset motherboard with four DDR5 slots supporting up to 192GB total. Storage includes two M.2 NVMe drives and a 10TB SATA hard drive requiring available bays and cables. A 1200W 80 PLUS Gold power supply with a 140mm fan is fitted. The 360mm liquid cooler needs clearance inside the 475 x 245 x 463 mm case.

Suits High-End Creative And AI Work

Buyers who need 24 cores, 128GB memory and a 32GB RTX 5090 for local inference or 3D rendering will match this specification. Users who only game or browse the web will not use the compute headroom. Builders who want a smaller chassis or a lower-wattage power supply should look at a different form factor.

Questions about this item

Does the system arrive with Windows 11 Pro installed and are the two 4TB Samsung 990 PRO SSDs already configured in the M.2 slots?

Yes, Windows 11 Pro 64-bit is pre-installed. The 8TB NVMe capacity is provided by two 4TB Samsung 990 PRO PCIe 4.0 drives factory-fitted to the motherboard M.2 connectors.

Should I choose the 128GB DDR5 configuration or add more memory later for AI workloads?

The board has four DDR5 slots and supports up to 192GB. The 128GB kit fills all slots, so any future increase means replacing modules rather than adding.

What does the RTX 5090 32GB GPU mean for 4K rendering and large-model inference in this build?

The 32GB frame buffer lets you hold larger textures and model weights on the card itself, reducing system-RAM swapping during 4K video export or AI inference tasks.
