Built for AI workloads and 4K gaming

This desktop pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 32GB GPU, 32GB DDR5 memory and a 4TB Samsung 990 PRO NVMe SSD. A 360mm liquid cooler and 1200W 80 PLUS Gold PSU support sustained high loads in a mid-tower case.

Suits creators and enthusiasts who need maximum

Buyers who want more storage than 4TB or who require ECC memory support should look elsewhere. The four DIMM slots allow expansion to 192GB, but the platform does not offer registered DIMM capability.

Deciding spec: RTX 5090 with 32GB VRAM

This single figure determines whether the system fits large-model inference, 8K video timelines or heavy 3D rendering. If the workload fits in less VRAM, a smaller GPU would cost less; if it needs more, this card cannot be expanded.

Questions about this item

Will the Z790 motherboard and 1200 W PSU run my existing PCIe 3.0 add-in cards and SATA drives?

The board provides four SATA 6 Gb/s ports and standard PCIe slots, so legacy PCIe 3.0 cards and SATA SSDs or HDDs will work normally. The 1200 W Gold unit supplies ample headroom for older peripherals.

How can I verify the i9-14900K is boosting to 6.00 GHz and the RTX 5090 is recognised with 32 GB VRAM?

Open Task Manager or HWMonitor to confirm the CPU hits 6.00 GHz under load and the GPU shows 32 GB dedicated memory. The 360 mm liquid cooler keeps thermals in check for sustained boost.

What ships inside the Antec P20 case and what must I add myself?

The system arrives fully assembled with the i9-14900K, 360 mm AIO, Z790 TUF board, 32 GB DDR5, 4 TB Samsung 990 PRO, RTX 5090, 1200 W PSU, Wi-Fi 6 and Windows 11 Pro. Only a monitor, keyboard and mouse are needed.
