A liquid-cooled tower workstation with a 24-core Intel Core Ultra 9 285K, 192 GB DDR5, RTX 5080 16 GB GPU and 1 TB NVMe SSD, ready for rendering, AI workloads and high-refresh gaming
This tower workstation ships with a 24-core Intel Core Ultra 9 285K processor running at 3.7 GHz with a 5.70 GHz maximum turbo. It targets professionals who need high thread counts for rendering, modelling and AI learning workloads. The system includes Windows 11 Pro and a 360 mm liquid cooler for sustained CPU performance.
Memory is fixed at 192 GB DDR5 across four slots, matching the platform maximum of 192 GB. The 1 TB Samsung 990 PRO NVMe drive delivers up to 7450 MB/s read and 6900 MB/s write speeds. Projects that exceed the single terabyte will require additional storage drives installed in the two 3.5-inch or two 2.5-inch internal bays.
A 360 mm quiet-edition AIO handles CPU thermals while front-mounted 140 mm PWM fans move air through the tempered-glass chassis. The Thermaltake Toughpower 1000 W 80 PLUS Gold unit provides overhead for the RTX 5080 16 GB GPU and full system load with protections for over-voltage, under-voltage, over-power and short-circuit.

No. The LGA 1851 socket is exclusive to Intel Core Ultra Series 2 processors, so earlier generation CPUs will not fit or function.
Open Task Manager or CPU-Z to verify memory shows 192 GB DDR5 and GPU-Z to confirm the RTX 5080 reports 16 GB VRAM and PCIe 4.0 x16 link width.
The tower, motherboard, CPU with 360 mm liquid cooler, 192 GB DDR5, 1 TB NVMe SSD, RTX 5080, 1000 W PSU and Windows 11 Pro are pre-installed; you only need to add a monitor, keyboard and mouse.
