Core Specification

This Adamant Custom desktop ships with a 24-core Intel Core Ultra 9 285K processor, 128GB of DDR5 memory, a 2TB NVMe SSD, a 10TB hard drive and a GeForce RTX 5090 graphics card with 32GB of video memory. It runs Windows 11 Pro on a Gigabyte Z890 Eagle motherboard and is cooled by a 360mm liquid cooler.

Target Builder

The system suits professionals who need high multi-threaded compute for rendering, modelling or AI workloads and who want a ready-to-run workstation with large local storage. Buyers who need more than 192GB of total memory capacity or who require a different motherboard chipset should look at alternative configurations.

Deciding Factor

The single specification that decides fit is the 24-core Intel Core Ultra 9 285K CPU paired with 128GB of DDR5 and the RTX 5090 32GB GPU, because this combination determines whether the machine can handle your specific rendering, simulation or training tasks.

Questions about this item

What CPU thermal limit appears first during an all-core workload on the 24-core Ultra 9 285K?

The 360 mm liquid cooler keeps the 24-core CPU within its thermal envelope so sustained all-core clocks hold at 3.7 GHz with boost up to 5.70 GHz.

How loud and hot does the system get when the RTX 5090 and 1200 W PSU run continuously?

The 360 mm quiet-edition AIO and 140 mm case fans keep noise low while the 1200 W 80 PLUS Gold PSU delivers stable power to the 32 GB GPU under full load.

Which display cables or adapters must I already own to use the RTX 5090 32 GB?

The RTX 5090 uses standard DisplayPort and HDMI outputs so existing DisplayPort or HDMI cables will connect your monitor immediately.
