Built for modelling, editing and AI learning

This Adamant Custom tower pairs a 12-core AMD Ryzen 9 9900X3D with an Nvidia GeForce RTX 5090 32GB GPU, 64GB DDR5 memory and 8TB of NVMe storage. Windows 11 Pro ships pre-installed and a 240 mm liquid cooler keeps the CPU quiet under heavy render loads.

Suits creators who need GPU compute

Buyers who want more than 64GB of memory or additional drive bays should look elsewhere. The four memory slots support up to 192GB total, but the system arrives with two 4TB Samsung 990 PRO SSDs already populating the M.2 slots.

12-core Ryzen 9 9900X3D with 128MB L3 cache

The processor reaches 5.50 GHz boost clocks and delivers 24 threads for parallel workloads. That core count and cache size are the single spec that decides whether this workstation matches your modelling, video editing or AI training pipeline.

Questions about this item

What clearance does the 240 mm liquid cooler need inside the case?

The CoolerMaster HAF 500 measures 508 mm deep by 203 mm wide by 508 mm high and has front 200 mm fans plus a rear 120 mm fan, giving room for the 240 mm radiator to mount at the front or top.

Which motherboard power connectors must be seated for the Ryzen 9 9900X3D and RTX 5090?

Plug the 24-pin ATX and the CPU 8-pin EPS into the TUF X870-PLUS board, then connect the PCIe power cables from the Thermaltake Toughpower 1200W unit to the RTX 5090; the step often missed is the second EPS cable if the board has an 8+4 layout.

When will the AIO coolant or the Samsung 990 PRO SSDs need attention?

The 240 mm Quiet Edition cooler is a sealed loop with no user-serviceable fill port, so plan a full unit swap after several years; each 4 TB 990 PRO drive is rated for high endurance and has no moving parts, so replacement is only needed if SMART data reports wear.
