Built for AI-ready workstation performance

This Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5070 12GB graphics card. A 4TB Samsung 990 PRO NVMe drive and a 10TB hard drive provide high-capacity storage. The system ships with Windows 11 Pro and a 240mm liquid cooler in a tempered-glass mid-tower case.

The Antec P20 chassis measures 469 by 220 by 490 millimetres and includes three 120mm front fans plus a 140mm PSU fan. The Thermaltake Smart 750W 80 PLUS Bronze supply uses standard ATX cables. The Z890 TUF motherboard offers four memory slots, four M.2 connectors and four SATA ports, all populated in this build.

Replaces a workstation limited to 64GB RAM

Builders moving from a platform capped at lower memory capacity or slower SSD speeds gain 192GB DDR5 and 7450 MB/s sequential reads. The jump is worth it when current render, simulation or multi-task workloads exceed available memory or storage throughput. Buyers needing more than two GPU slots or a larger chassis should look elsewhere.

Questions about this item

What comes inside the Antec P20 case and do I need to buy a monitor, keyboard or mouse separately?

The system ships with the liquid-cooled Core Ultra 7 265K, 192 GB DDR5, 4 TB Samsung 990 PRO NVMe, 10 TB HDD, RTX 5070 12 GB GPU, Windows 11 Pro, Wi-Fi 7 and Bluetooth 5.4. No screen, keyboard or mouse are included.

Should I pick the 192 GB DDR5 configuration or is a lower capacity available for this model?

The motherboard has four slots and the maximum supported is 192 GB, so this build already uses the full capacity. No smaller DDR5 option is offered for this exact configuration.

What does the 5.50 GHz boost clock on the 20-core Core Ultra 7 265K mean for real workloads?

The processor can reach 5.50 GHz on active cores with 30 MB L3 cache, giving strong single-thread speed for gaming and quick response in creative apps while the 20 cores handle heavy multi-thread rendering or compile jobs.
