Adamant Custom Intel Core Ultra 9 285K RTX 5090 192GB DDR5 gaming PC

24-Core Workstation for AI and Rendering

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. The liquid-cooled chassis houses a 2TB NVMe SSD and a 10TB hard drive. It targets professionals who need sustained multi-threaded throughput for rendering, modelling and AI learning workloads. Windows 11 Pro is pre-installed.

DDR5 Capacity Ceiling at 192GB

The Z890 motherboard provides four memory slots and supports a maximum of 192GB, which this system already populates. No further RAM upgrades are possible without replacing modules. The board also offers four M.2 connectors and four SATA ports for additional NVMe or SATA storage expansion. Rear I/O includes Thunderbolt 4 and multiple USB 20Gbps and 10Gbps ports.

32GB GPU Memory Defines the AI Limit

The GeForce RTX 5090 supplies 32GB of video memory, which sets the practical ceiling for single-GPU model training and high-resolution texture work. The 1200W 80 PLUS Gold power supply delivers the necessary headroom for the full system. Buyers who need more GPU memory must consider multi-GPU configurations or accelerator cards instead.
