Tower workstation for AI and rendering

This tower workstation pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 and 192GB of DDR5 memory. It targets professionals running local AI inference, 3D rendering or heavy multitasking workloads. Windows 11 Pro ships pre-installed on a 1TB Samsung 990 PRO NVMe drive. All configurations remain customisable before dispatch.

360mm liquid cooler and 1200W Gold PSU

A 360mm Quiet Edition AIO handles CPU thermals while a 140mm PSU fan keeps power delivery noise low. The Thermaltake Toughpower 1200W 80 PLUS Gold unit includes Japanese main capacitors and over-voltage, under-voltage, over-power and short-circuit protection. Three 120mm front case fans feed airflow through dust filters on bottom, front and top panels.

Samsung 990 PRO SSD and Z790 TUF connectivity

The bundled 1TB Samsung 990 PRO delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s over PCIe 4.0x4. The Z790 TUF motherboard adds Wi-Fi 6, BLUETOOTH 5.2, Intel 2.5Gb Ethernet, four M.2 slots, four SATA 6Gb/s ports and front-panel USB 3.2 Gen 2 Type-C. Realtek 7.1 surround audio completes the I/O.

Questions about this item

How is the 360 mm liquid cooler installed, and which step do builders often get wrong?

The 360 mm radiator mounts to the top or front of the Antec P20 case using the included brackets; the step most people miss is orienting the tubes at the bottom of the radiator so air cannot collect in the pump block.

What maintenance or replacement will the liquid cooler and the 1200 W PSU need later?

The sealed 360 mm AIO requires no coolant top-ups, but the 140 mm radiator fans and the three 120 mm front case fans should be cleaned or swapped when dust builds up; the PSU fan may need replacement after several years of continuous load.

Which limit appears first during sustained heavy workloads on the i9-14900K and RTX 5090?

The CPU can draw enough power to hit its thermal throttle point before the 360 mm AIO saturates, so processor temperature under prolonged all-core boost is the first bottleneck you will see.
