Built for extreme workloads

This Adamant Custom tower pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 graphics card. Thirty-two gigabytes of DDR5 memory and a 1 TB NVMe SSD keep data flowing for 3D rendering, simulation or competitive gaming. Windows 11 Pro ships pre-installed on a liquid-cooled platform designed for sustained heavy use.

GPU memory decides the ceiling

The RTX 5090 brings 32 GB of video memory, the single figure that determines whether massive textures, point-cloud datasets or multi-monitor 4K workloads fit without swapping. System RAM tops out at 192 GB across four slots, so the 32 GB fitted today can grow later. Storage combines the 1 TB NVMe boot drive with a 10 TB mechanical drive for bulk archives.

Installation is largely finished

The PC arrives assembled, tested and ready to power on. Liquid cooling uses a 360 mm radiator mounted in the Corsair 4000D case, so verify the front panel has clearance for the tubing run. Internal bays include two 3.5-inch and two 2.5-inch slots if extra drives are added later. The 1200 W 80 Plus Gold PSU uses standard ATX cables; route them before the first boot to avoid airflow blockage.

Questions about this item

How does the 24-core i9-14900K perform when all cores are loaded in this liquid-cooled tower?

The 360 mm AIO keeps the CPU at its 3.2 GHz base and lets it reach the 6.00 GHz boost across its 24 cores and 32 threads without thermal throttling.

What does the PCIe 4.0 x4 link mean for the Samsung 990 PRO SSD in daily use?

The four-lane Gen 4 connection caps sequential reads at 7450 MB/s and writes at 6900 MB/s, so large game loads and file transfers hit those ceilings.

Will the RTX 5090 32 GB fit in the Corsair 4000D case alongside the 360 mm radiator?

Yes — the 490 mm deep chassis has room for a front-mounted 360 mm radiator and a full-length graphics card, and the 1200 W Gold PSU supplies the required power.
