Built for demanding professional workloads

This business desktop pairs a 20-core Intel Core Ultra 7 265K processor with 128GB of DDR5 memory and an Nvidia RTX A400 graphics card. A 240mm liquid cooler keeps the CPU stable under sustained load while the system runs Windows 11 Pro out of the box.

Suits users who need multi-threaded compute

Creative professionals, engineers and analysts who rely on GPU-accelerated applications will benefit from the workstation-class graphics and high memory capacity. Buyers who require multiple full-size GPUs or more than four display outputs should consider a larger chassis.

2TB NVMe primary drive plus 10TB secondary storage

The Samsung 990 PRO delivers up to 7450 MB/s reads and 6900 MB/s writes for active projects, while the 10TB hard drive with 256MB cache holds deep archives. Motherboard memory ceiling is 192GB, so 128GB leaves room for future expansion.

Questions about this item

What display connectors do I need on my monitors to use the RTX A400 4GB 4xMiniDP?

You will need monitors with Mini DisplayPort inputs or suitable MiniDP-to-DP/HDMI adapters for each of the four MiniDP outputs on the RTX A400.

Can I keep my existing 2.5G Ethernet switch and Wi-Fi 7 router with this desktop?

Yes, the onboard Intel 2.5Gb Ethernet and Wi-Fi 7 2x2 (802.11be) / Bluetooth 5.4 are compatible with existing 2.5G switches and Wi-Fi 7 routers.

How can I verify the 128GB DDR5 is running at full capacity after setup?

Open Task Manager > Performance > Memory and confirm 128 GB appears; the motherboard supports up to 192 GB, so 128 GB indicates all modules are detected.
