24-Core Workstation Desktop

This system pairs a 24-core Intel Core i9-14900K with 64GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. It ships with Windows 11 Pro installed on a 1TB NVMe SSD. The tower chassis uses liquid cooling for the processor. It targets professionals who need high single-thread speed and large GPU memory for rendering, modelling or AI workloads.

Upgrade From Thread-Limited Rigs

The 24-core 32-thread design replaces platforms that stall on heavy multi-tasking or large scene parsing. The jump is worth it when 36 MB of L3 cache and 6.00 GHz peak frequency cut compile times or frame-export queues. Builders who need more than 64GB can expand to 192 GB across four total slots.

Sustained Load Behaviour

A 360 mm quiet-edition liquid loop keeps the CPU stable during long renders without the acoustic spikes of air coolers. The Thermaltake Toughpower 1200W 80 PLUS Gold unit delivers steady power through over-voltage, under-voltage and short-circuit protection. The Corsair 4000D case moves air through tempered-glass panels while housing two 3.5-inch and two 2.5-inch internal bays.

Questions about this item

Will a 360 mm liquid cooler fit in the Corsair 4000D case?

The case measures 490 x 239 x 486 mm and the build already includes a 360 mm AIO, so the radiator and fans are confirmed to fit.

How do I install the 64 GB DDR5 kit on the Z790 motherboard?

Seat the modules in the two primary slots first — usually the second and fourth from the CPU — then enable XMP in the BIOS to reach the rated speed.

When will the Samsung 990 PRO 1 TB SSD need replacement?

The drive is rated for up to 7450 MB/s read and 6900 MB/s write; monitor SMART health and replace once the endurance indicator approaches its limit.
