Adamant Custom 24-Core Ultra 9 285K Workstation

This Adamant Custom gaming desktop PC pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5090 graphics card. It includes 64GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe solid-state drive. A 360mm liquid cooler and 1200W 80 PLUS Gold power supply support the high-performance components. The system ships with Windows 11 Pro installed.

Suits AI modelling and 4K rendering.

The specification targets professionals running AI learning, rendering and complex modelling workloads that demand 24 cores and 32GB of GPU memory. Wi-Fi 7 and 2.5Gbps LAN provide fast network connectivity for collaborative projects. Buyers who only need mainstream gaming performance or general office productivity should consider less expensive configurations that match those lighter requirements.

32GB RTX 5090 frame buffer drives AI and 4K choice

The GeForce RTX 5090 equipped with 32GB of video memory is the single specification that determines suitability for large-model AI training and high-resolution content creation. This capacity allows datasets and textures to remain resident on the GPU, avoiding system-memory swaps that slow iteration. If your workflow fits within a smaller frame buffer, a lower-tier graphics card will reduce cost without limiting performance.

Questions about this item

How high can the Intel Core Ultra 9 285K boost before it hits its thermal ceiling?

The 24-core CPU can reach up to 5.70 GHz, and the 360 mm liquid cooler is built to keep temperatures in check during long rendering or AI workloads.

What noise and heat levels should I expect when the RTX 5090 and CPU run flat out all day?

The Quiet Edition 360 mm AIO and the Thermaltake 1200 W Gold PSU with its ultra-quiet 140 mm fan are designed for low noise, while the mid-tower case uses two front 140 mm PWM fans for steady airflow.

Which display cables or adapters do I need to have on hand before this PC arrives?

The RTX 5090 uses modern display outputs, so ensure your monitor has compatible inputs such as DisplayPort or HDMI; the front panel also provides a USB 3.2 Gen 2x2 Type-C port for peripherals.
