Built for AI and 4K creation

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU, 32GB DDR5 memory and a 2TB Samsung 990 PRO NVMe drive. A 10TB HDD adds bulk storage. The system is liquid cooled and ships with Windows 11 Pro.

Suits creators and high-refresh gamers

The 24-core CPU and flagship GPU handle heavy rendering, simulation and 4K gaming workloads. Buyers who need more than 32GB RAM out of the box should note the four slots support up to 192GB total. The single RTX 5090 configuration does not serve multi-GPU compute clusters.

The processor delivers 24 cores with a 3.7GHz base and up to 5.70GHz boost on the LGA 1851 platform. This core count and clock envelope decide whether the system meets your parallel-processing or single-thread targets.

Questions about this item

Use the 2TB Samsung 990 PRO NVMe for the operating system and active games — it reads up to 7450 MB/s and writes up to 6900 MB/s. Keep the 10TB HDD with 256MB cache for bulk media and backups.

What does the 24-core Core Ultra 9 285K actually deliver in this build?

The CPU runs at a 3.7 GHz base and can boost to 5.70 GHz with 36 MB L3 cache, cooled by a 360mm quiet-edition liquid loop on the Gigabyte Z890 UD motherboard.

Which Wi-Fi and wired standards are built in, and what speeds do they cap at?

The board includes Intel Wi-Fi 6E AX211 with Bluetooth 5.3 on 2.4/5/6 GHz bands plus a 2.5 Gbps Ethernet port.
