A 24-core Intel Core Ultra 9 285K and GeForce RTX 5090 32GB desktop with 128GB DDR5, 8TB NVMe storage and liquid cooling for rendering, AI learning and high-end gaming
This desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU and 128GB DDR5 memory. It targets professionals running local AI learning, 3D modelling and high-resolution video editing workloads. The system ships with Windows 11 Pro installed on an 8TB NVMe array.
A 360mm quiet-edition AIO cooler handles the CPU while an ultra-quiet 140mm fan runs inside the Thermaltake Toughpower 1200W 80 PLUS Gold supply. The PSU uses Japanese main capacitors and provides over-voltage, under-voltage, over-power and short-circuit protection. Liquid cooling and the low-noise fan keep acoustics restrained during sustained compute tasks.
The tempered-glass tower measures 490 x 239 x 486 mm and offers internal bays for two 3.5-inch and two 2.5-inch drives. Front I/O includes one USB 3.2 Type-C, two USB 3.2 Gen 1 and a combo audio jack. Rear I/O adds one USB4 Type-C, one USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports plus Intel 2.5Gb Ethernet, Wi-Fi 6E and Bluetooth 5.3.

Mount the 360 mm radiator at the top or front using the included brackets, then connect the pump header to the CPU_FAN connector on the Z890 UD motherboard; the step most builders forget is plugging the pump tach cable into CPU_FAN so the BIOS can monitor pump speed.
The sealed 360 mm AIO requires no coolant refill, but plan to clean the radiator fins and replace the 140 mm fans every few years; the Thermaltake Toughpower 1200 W 80 PLUS Gold unit should have its dust filter cleaned annually and the fan checked for bearing noise after prolonged heavy loads.
The 1200 W Gold PSU caps total system draw, so under combined CPU and GPU stress the power limit is reached before the 360 mm liquid cooler saturates, causing the motherboard to throttle the 24-core processor to stay within the 1200 W envelope.
