20-Core Ultra 7 Workstation

This gaming desktop PC pairs a 20-core Intel Core Ultra 7 265K processor with 128GB DDR5 memory and a 4TB NVMe SSD. The system ships with Windows 11 Pro and a liquid-cooled CPU running at 3.7GHz base frequency. It targets professionals who need high single-thread speed and large memory capacity for rendering, modelling or AI learning workloads.

32GB RTX 5090 GPU and 1000W Gold PSU

The Nvidia Geforce RTX 5090 graphics card brings 32GB video memory for large scene rendering and GPU-accelerated compute. A Thermaltake Toughpower 1000W 80 PLUS Gold power supply with Japanese main capacitor and 140mm quiet fan delivers stable power under sustained load. The Z890 TUF motherboard adds Thunderbolt 4, USB 20Gbps and Wi-Fi 7 connectivity for fast peripheral and network links.

Suits creators needing max GPU memory

Buyers who want more storage than the single 4TB NVMe drive provides should look elsewhere. The 240mm liquid cooler and mid-tower case limit future GPU upgrades to cards that fit the existing clearance. Users who require dual-GPU configurations or additional 3.5-inch drive bays will need a larger chassis and higher-wattage power supply.

Questions about this item

How often should the liquid in the 240mm AIO cooler be checked or replaced?

The 240mm Quiet Edition AIO is a sealed maintenance-free loop; no liquid top-ups or changes are required during its service life.

Which component hits its thermal or power ceiling first when the CPU runs at 5.50 GHz and the GPU at full load?

The 1000W 80 PLUS Gold PSU sets the overall power ceiling; sustained 5.50 GHz CPU and RTX 5090 loads stay within its rated output.

How loud is the 140mm PSU fan and the AIO pump when the system renders all day?

The PSU uses an ultra-quiet 140mm fan and the AIO is a Quiet Edition design; both are engineered for low noise under continuous load.
