Tower workstation for creators and AI developers

This Adamant Custom desktop combines a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 in a liquid-cooled Corsair 4000D tower. Windows 11 Pro ships pre-installed on a 1 TB Samsung 990 PRO NVMe drive. The 1200 W 80 PLUS Gold PSU powers the build.

64 GB DDR5 with 192 GB ceiling

Four DDR5 slots hold 64 GB today and support up to 192 GB for larger datasets. The 1 TB NVMe SSD delivers 7450 MB/s reads and 6900 MB/s writes for active projects. A 10 TB HDD with 256 MB cache stores archives and bulk assets.

Replaces dual-machine CPU/GPU split workflows

Builders who currently render on a thread-heavy CPU box and train models on a separate GPU rig can consolidate to this single tower. The jump is worth it when 24 cores, 32 GB VRAM and fast shared storage cut data-transfer steps between machines.

Questions about this item

Will the LGA 1700 socket on the Z790 PRIME motherboard accept my existing DDR5 memory kit?

The board has four DDR5 slots and supports up to 192 GB, so any compatible DDR5 modules you already own can be installed alongside the 64 GB supplied.

How can I verify the RTX 5090 is running at full performance after I build the system?

Check that the GPU shows 32 GB VRAM in Task Manager, confirm the 1200 W 80 PLUS Gold PSU is connected, and run a benchmark to see clock speeds reach the advertised boost.

Which components come pre-installed in the Corsair 4000D case and what must I source myself?

The system ships fully assembled with CPU, 360 mm liquid cooler, motherboard, 64 GB DDR5, 1 TB Samsung 990 PRO SSD, 10 TB HDD, RTX 5090, 1200 W PSU and Windows 11 Pro; only peripherals and a display are needed separately.
