High-end workstation and gaming tower

This desktop combines a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card. It targets professionals who need heavy rendering, modelling or AI learning performance alongside high-frame-rate gaming. The system ships with Windows 11 Pro installed and uses a black Cooler Master HAF 500 case with tempered glass panels.

Liquid CPU cooling and 1200W Gold power supply

A 360 mm quiet-edition all-in-one cooler handles the processor while the Thermaltake Toughpower 1200W 80 PLUS Gold unit delivers power with Japanese main capacitors and a 140 mm low-noise fan. Case airflow uses two 200 mm front ARGB fans, one 120 mm rear ARGB fan and a dedicated 120 mm GPU fan. Over-voltage, under-voltage, over-power and short-circuit protections are included.

64 GB DDR5 memory expandable to 192 GB

Four DDR5 slots are populated with 64 GB of high-performance modules and the Gigabyte Z790 AORUS motherboard supports up to 192 GB total. This capacity ceiling determines whether the machine can hold the datasets or virtual machines a specific workflow requires. Storage uses two 4 TB Samsung 990 PRO PCIe 4.0 x4 NVMe drives and a 10 TB hard drive with 256 MB cache.

Questions about this item

How do I install the 360 mm AIO liquid cooler in the CoolerMaster HAF 500 case, and which step is often missed?

Mount the 360 mm radiator to the top or front using the included brackets, then connect the pump header to the CPU_FAN connector on the GIGABYTE Z790 AORUS motherboard; the step most builders forget is plugging the pump tach cable into that specific header so the BIOS can monitor flow.

What maintenance or replacement will the 360 mm AIO liquid cooler and the 1200 W 80 PLUS Gold PSU need later?

The AIO is a sealed unit — plan to replace the whole cooler after roughly five years when pump performance drops; the PSU fan may need cleaning or replacement if noise rises, and its Japanese main capacitors are rated for long life but should be inspected during any major teardown.

What limit appears first when the Intel Core i9-14900K runs sustained all-core loads at up to 6.00 GHz with the 360 mm AIO?

The CPU will hit its thermal junction limit and throttle before the 360 mm AIO can dissipate the full 24-core load, so sustained clocks settle below the 6.00 GHz single-core maximum.
