Adamant Custom Intel Core Ultra 9 285K RTX 5090 192GB DDR5 1TB NVMe 10TB HDD Gaming PC

Ready-built AI workstation

This desktop ships with a 24-core Intel Core Ultra 9 285K processor, an Nvidia GeForce RTX 5090 graphics card with 32GB of video memory, and 192GB of DDR5 system memory. A 1TB Samsung 990 PRO NVMe drive handles the operating system and active projects while a 10TB hard drive provides bulk storage. Liquid cooling and a 1200W 80 PLUS Gold power supply complete the package.

Suited to local model training and heavy rendering

The 192GB memory ceiling and the RTX 5090’s 32GB frame buffer make this system viable for large-language-model inference, complex 3D scenes and multi-layer video timelines. Buyers who need more than 192GB of RAM or who require multiple GPUs for distributed training should look at a different platform. The four-slot motherboard is already fully populated, so further memory upgrades are not possible.

Deciding specification: 192GB DDR5 memory limit

The motherboard supports a maximum of 192GB across four slots, and this build fills every slot. That figure is the hard boundary for any workload that must reside entirely in system memory; if your datasets exceed it you will need a workstation-class board with a higher ceiling.
