Built for intensive workloads

This desktop combines a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card carrying 32GB of video memory. It targets professionals who need sustained compute for editing, rendering, modelling and AI learning alongside high-end gaming performance. The 128GB DDR5 configuration and 4TB NVMe storage are sized for large project files and multi-tasking.

Straightforward out-of-the-box setup

The system arrives fully assembled with Windows 11 Pro installed and a 360mm liquid cooler already mounted on the CPU. Common issues are limited to transit-related cable seating or a GPU power connector that needs a firm push; the CoolerMaster HAF 500 case provides wide access panels to resolve both quickly. No motherboard standoff or cooler bracket work is required.

Verify power and expansion needs

Confirm your mains outlet can support the 1200W 80 PLUS Gold power supply and that your desk space accommodates the 508mm depth and 508mm height of the mid-tower chassis. The Gigabyte Z790 AORUS motherboard offers four M.2 slots and six SATA ports for future drives, while rear I/O includes USB 3.2 Gen 2 Type-C, 2.5Gb Ethernet and Wi-Fi 6 with Bluetooth 5.2.

Questions about this item

How do I verify the 24-core i9-14900K and RTX 5090 are running correctly after first boot?

Open Task Manager Performance tab to confirm 24 cores and 32 threads are detected, then run GPU-Z to verify the RTX 5090 shows 32 GB VRAM and the Samsung 990 PRO reports read speeds near 7450 MB/s.

What components are included in the box and what must I purchase separately?

The system ships fully assembled with the CoolerMaster HAF 500 case, 360 mm liquid cooler, Z790 AORUS motherboard, 128 GB DDR5, 4 TB Samsung 990 PRO SSD, RTX 5090, 1200 W Gold PSU, Wi-Fi 6 and BLUETOOTH 5.2, plus Windows 11 Pro. Only a monitor, keyboard and mouse are needed separately.

Which memory capacity should I choose between the listed 128 GB and the 192 GB maximum?

The build arrives with 128 GB DDR5 installed across four slots; the board supports up to 192 GB, so select 128 GB for current high-end workloads or 192 GB if you plan heavy AI training or large-scale rendering that exceeds 128 GB.
