Purpose-built workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5080 16GB GPU and 64GB DDR5 memory. It targets creators and engineers who need strong single-thread speed plus hardware-accelerated AI compute in a single mid-tower chassis.

Capacity and headroom

The 4TB Samsung 990 PRO PCIe 4.0x4 NVMe drive delivers up to 7450 MB/s reads and 6900 MB/s writes, keeping large project files and model weights local. Four DIMM slots support up to 192GB total DDR5, so memory can grow well beyond the factory 64GB when workloads demand it.

Build integration

A 360mm liquid cooler and 1000W 80 PLUS Gold PSU handle the 285K and RTX 5080 thermals and power draw without extra parts. The Gigabyte Z890 Eagle motherboard adds Wi-Fi 7, Bluetooth5.4, 2.5Gb Ethernet, USB4 and four M.2 slots, while the case provides two 3.5-inch and two 2.5-inch bays for future storage expansion.

Questions about this item

Can I add more DDR5 memory later to reach the 192 GB limit using the four total slots?

Yes, the motherboard has four DDR5 slots and supports up to 192 GB total, so you can populate the remaining slots with compatible DDR5 modules to expand beyond the installed 64 GB.

How can I verify the RTX 5080 is running at full performance after I set up the PC?

Open the NVIDIA control panel or GPU-Z to confirm the RTX 5080 16 GB is detected, then run a benchmark or game and check that GPU utilisation reaches near 100 % with expected clock speeds.

What components are included in the box and what must I provide myself?

The system ships fully assembled with the Intel Core Ultra 9 285K, 64 GB DDR5, 4 TB Samsung 990 PRO NVMe, RTX 5080 16 GB, 360 mm liquid cooler, 1000 W 80 PLUS Gold PSU, Windows 11 Pro, Wi-Fi 7 and Bluetooth 5.4; you only need a monitor, keyboard and mouse.
