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.

Questions about this item

Should I pick the 192GB DDR5 configuration or a smaller kit for AI workloads?

The system ships with 192GB DDR5 across four slots, which matches the motherboard maximum and leaves no room for expansion.

What does the 5.70GHz boost clock on the Core Ultra 9 285K deliver in daily rendering?

The 24-core CPU can reach 5.70GHz on light threads, cutting single-thread compile times while the 36MB L3 cache keeps multi-frame renders fed.

How does the Thunderbolt 4 Type-C port limit external GPU or storage speeds?

The rear Thunderbolt 4 port caps at 40Gbps, so an external NVMe enclosure will run at PCIe 4.0x4 speeds while a GPU dock is limited to four lanes.
