Adamant Custom 20-Core Business Desktop

The Adamant Custom system is a liquid-cooled business desktop built around a 20-core Intel Core Ultra 7 265K processor running at 3.9 GHz. It ships with 32 GB of DDR5 memory, a 4 TB NVMe SSD and a 10 TB hard drive. The Nvidia RTX A400 graphics card provides four Mini DisplayPort outputs and 4 GB of video memory. Windows 11 Pro 64-bit is pre-installed and the chassis includes 2.5 Gb Ethernet plus Wi-Fi 7 connectivity.

Suited for multi-threaded workloads

This desktop suits professionals who need high core counts for compiling, virtualisation or content creation and who drive up to four monitors from a single card. The 32 GB DDR5 baseline and 192 GB maximum memory supported allow headroom for large datasets. Buyers who need more than 4 GB of GPU memory for intensive 3D rendering or compute tasks should consider a workstation with a larger graphics frame buffer. The single RTX A400 also limits configurations that require multiple add-in cards.

4 GB RTX A400 with four Mini DisplayPort outputs

The installed Nvidia RTX A400 carries 4 GB of video memory and four Mini DisplayPort connectors, making it the decisive spec for display-heavy workflows. It occupies a PCI Express x16 slot and supports virtual reality applications. If your software demands a larger frame buffer or additional GPU compute resources, this card will be the limiting factor.

Questions about this item

Can I connect my existing monitors to the RTX A400 4GB 4xMiniDP outputs?

The RTX A400 provides four Mini DisplayPort outputs; use MiniDP-to-DisplayPort or MiniDP-to-HDMI cables to connect your current screens.

How do I verify the 240mm liquid cooler is running after I power on the system?

Listen for the pump hum and check that the CPU temperature stays near idle levels in the BIOS or Windows Task Manager.

What storage drives are already installed and what would I need to add more?

A 4TB Samsung 990 PRO NVMe SSD and a 10TB 256MB cache HDD are fitted; the motherboard has four M.2 slots and four SATA ports for extra drives.
