24-Core Workstation for AI and Rendering

This tower desktop combines a 24-core Intel Core i9-14900K processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. Two Samsung 990 PRO SSDs provide 8TB of NVMe storage. A 360mm liquid cooler and a 1200W 80 PLUS Gold power supply support sustained workloads. Windows 11 Pro is pre-installed.

Suits creators training models or editing 8K footage

The 128GB memory ceiling and 32GB GPU frame buffer handle large datasets and complex scenes. Builders who need more than 192GB of system memory or additional internal drive bays beyond the four provided should look at a different platform. The mid-tower chassis limits expansion card length and radiator mounting options.

Bundled Samsung 990 PRO drives deliver 7450 MB/s

This speed shortens project load times and accelerates cache-heavy workflows. The Thermaltake Toughpower 1200W unit adds over-voltage, under-voltage, over-power and short-circuit protection for stable delivery under full load. Wi-Fi 6 and Bluetooth 5.2 on the Z790 TUF motherboard replace wired connections where cabling is impractical.

Questions about this item

What monitor connections does the RTX 5090 32GB GPU provide for my existing displays?

The RTX 5090 32GB graphics card includes DisplayPort and HDMI outputs, so current monitors with those inputs will work without adapters.

Will my older SATA SSDs or hard drives fit inside the Antec P20 case alongside the 8TB NVMe storage?

Yes, the case has two internal 3.5"/2.5" bays and two dedicated 2.5" bays, and the motherboard supplies four SATA 6Gb/s ports for legacy drives.

How can I confirm the 128GB DDR5 memory is running at its rated speed after first boot?

Open Task Manager's Performance tab or BIOS; the memory speed shown should match the DDR5 kit's rated frequency.
