24-Core Workstation for Rendering and AI

This system is built around a 24-core Intel Core Ultra 9 285K processor and an Nvidia GeForce RTX 5090 graphics card with 32GB of video memory. It targets professionals who need strong multi-threaded CPU performance combined with high-end GPU compute for 3D rendering, video editing, modelling and AI learning workloads. The 64GB of DDR5 memory and 1TB NVMe SSD provide a fast foundation for large project files and active datasets. Windows 11 Pro is pre-installed on the tower chassis.

Pre-Assembled Tower with Liquid Cooling

The computer arrives fully assembled inside a Corsair 4000D Series tempered glass case measuring 490 x 239 x 486 mm. A 360mm quiet-edition AIO liquid cooler handles the CPU, while the Thermaltake Toughpower 1200W 80 PLUS Gold power supply uses a 140mm fan and Japanese main capacitors. Because the build is complete, the only physical installation required is placing the tower and connecting peripherals. Builders who prefer to choose their own components or who need a smaller form factor will not be served by this pre-configured unit.

64GB DDR5 and 1TB NVMe with Expansion Room

The Gigabyte Z890 UD motherboard populates two of its four DDR5 slots with 64GB of high-performance memory and supports a maximum of 192GB for future upgrades. The 1TB Samsung 990 PRO PCIe 4.0x4 NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s. Three additional M.2 connectors and two 3.5-inch plus two 2.5-inch drive bays remain open for extra storage. Users whose active working set exceeds 64GB of RAM or 1TB of fast storage will need to add modules or drives to avoid paging or capacity limits.

Questions about this item

How can I verify the liquid cooler is running after I power on the system?

The 360 mm Quiet Edition AIO uses a 140 mm fan; listen for the pump hum and watch the fan spin through the tempered glass panel, then confirm CPU temperatures stay low in Windows 11 Pro.

What components are included and what must I supply myself?

The tower ships fully assembled with the Intel Core Ultra 9 285K, 64 GB DDR5, 1 TB Samsung 990 PRO NVMe, RTX 5090 32 GB, 1200 W 80 PLUS Gold PSU, Z890 motherboard with Wi‑Fi 6E and Bluetooth 5.3, and Windows 11 Pro — only a monitor, keyboard and mouse are needed.

Which memory capacity should I choose if I plan to upgrade later?

The board has four DDR5 slots and supports up to 192 GB, so the installed 64 GB leaves three free slots for future expansion.
