Workstation for CAD and AI

The Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K with an Nvidia RTX PRO 5000 Blackwell GPU carrying 48GB of memory. Thirty-two gigabytes of DDR5 RAM and a 2TB NVMe SSD provide fast access to active projects, while a 10TB hard drive stores large datasets. Windows 11 Pro 64-bit ships pre-installed on a platform built for SolidWorks modelling and AI workloads.

Liquid cooling and 850W supply

A 240mm quiet-edition liquid cooler handles the CPU, while three 120mm front fans and a 140mm PSU fan move air through the tempered-glass mid-tower. The Thermaltake Smart 850W 80 PLUS Bronze unit includes Japanese main capacitors and protections against over-voltage, under-voltage, over-power and short-circuit. Dust filters on bottom, front and top panels reduce particulate build-up during extended render sessions.

Connectivity and expansion layout

The Z890 motherboard rear I/O offers Thunderbolt 4 Type-C, one USB 20Gbps Type-C, three USB 10Gbps and three USB 5Gbps ports alongside 2.5G Ethernet, Wi-Fi 7 and Bluetooth 5.4. Internal headers add a front-panel USB 20Gbps Type-C, USB 5Gbps, two USB 2.0, four SATA 6Gb/s and four M.2 slots. The case provides two 3.5-inch and two 2.5-inch internal bays for further storage upgrades.

Questions about this item

How do I install the 240 mm liquid cooler on the LGA 1851 socket and what step is often missed?

Mount the supplied bracket for LGA 1851, apply thermal paste, secure the water block, connect the pump header and route the 120 mm radiator fans to the CPU fan header so the BIOS controls pump speed.

Which components will need replacement first during the workstation's service life?

The 850 W PSU electrolytic capacitors and the 140 mm PSU fan typically age before the 2 TB NVMe SSD or 10 TB HDD; plan a PSU swap after several years of heavy loads.

What thermal or power limit appears first when the 20-core CPU and 48 GB GPU run sustained workloads?

The 240 mm radiator surface area and 850 W PSU ceiling cap combined CPU-GPU draw before the CPU hits its 5.50 GHz turbo or the GPU reaches its 48 GB VRAM ceiling.
