Built for Heavy Compute

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with 192GB DDR5, a 4TB NVMe drive, 10TB HDD and an RTX 5090 32GB GPU. It targets creators and researchers who run rendering, modelling or AI learning workloads that demand both massive memory capacity and high single-thread frequency up to 5.70 GHz.

Ready to Run

The system arrives fully assembled with Windows 11 Pro installed and a 360mm liquid cooler mounted on the LGA 1851 socket. The Corsair 4000D case uses standard ATX layout, so the only common issue is confirming that the 1200W PSU cables reach your chosen GPU power connectors without strain.

Check Your Workspace

Verify that your desk can accommodate the mid-tower dimensions of 490 x 239 x 486 mm and that your monitor inputs match the RTX 5090 display outputs. Ensure your network infrastructure can use the 2.5Gbps LAN or Wi-Fi 6E AX211 wireless, and that you have a free Bluetooth 5.3 channel for peripherals.

Questions about this item

How do I confirm the Intel Core Ultra 9 285K is reaching its 5.70 GHz boost after setup?

Open Task Manager or a monitoring utility and watch the CPU frequency under load; the 24-core processor should show speeds up to 5.70 GHz when thermal headroom allows.

What components are included and what must I buy separately?

The system ships complete with the Corsair 4000D case, 1200W 80 PLUS Gold PSU, 360 mm liquid cooler, Gigabyte Z890 UD motherboard, 192 GB DDR5, 4 TB Samsung 990 PRO NVMe, 10 TB HDD, RTX 5090 32 GB GPU and Windows 11 Pro; only a monitor, keyboard and mouse are needed separately.

Which SSD capacity should I choose for the primary drive?

The 4 TB Samsung 990 PRO PCIe 4.0 x4 NVMe is the sole primary SSD in this configuration, delivering up to 7450 MB/s read and 6900 MB/s write; no alternative capacity is offered for the boot drive.
