24-Core i9-14900K Workstation

This system pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5080 16GB GPU. It ships with 128GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe drive plus a 10TB hard drive. The build targets creators who need high thread counts for rendering, modelling and AI workloads while keeping a mid-tower footprint.

Pre-built liquid cooling and Windows 11 Pro

The CPU is cooled by a 360mm quiet-edition AIO that arrives already filled and mounted. Windows 11 Pro 64-bit is installed and activated, so the machine boots straight to the desktop. The only common snag is the front-panel USB-C header, which needs a compatible motherboard connector that is present on the included Z790 TUF board.

Check power and case clearance before ordering

The Thermaltake Toughpower 1000W 80 PLUS Gold unit supplies the CPU and GPU, so verify your mains circuit can handle the draw. The Antec P20 mid-tower measures 469mm deep by 490mm high, so confirm your desk or rack space accommodates those dimensions. The board offers four DDR5 slots with a 192GB ceiling if you plan to expand later.

Questions about this item

How can I confirm the 360 mm liquid cooler is keeping the i9-14900K at safe temperatures after setup?

Open the BIOS or a monitoring utility such as HWMonitor and watch the CPU package temperature; at idle it should sit well below 50 °C and under sustained load stay under the 100 °C throttle point, showing the 360 mm AIO is doing its job.

Which components are already installed in the Antec P20 case and which items must I source myself?

The system ships fully assembled with the Z790 TUF motherboard, i9-14900K, 128 GB DDR5, 4 TB Samsung 990 PRO NVMe SSD, 10 TB HDD, RTX 5080 16 GB GPU, 1000 W 80 PLUS Gold PSU, 360 mm AIO cooler, three 120 mm front fans, Wi-Fi 6 and Bluetooth 5.2 — only a monitor, keyboard and mouse are left to add.

Should I choose the 128 GB DDR5 configuration or upgrade to the 192 GB maximum the board supports?

The board has four slots and supports up to 192 GB; 128 GB already fills all slots with high-performance DDR5, so moving to 192 GB would require replacing every module — only do it if your rendering or AI workloads regularly exceed 128 GB.
