Custom workstation for rendering and AI

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5080 16GB graphics card. The system targets professionals who need high throughput for 3D modelling, video editing and local AI learning workloads. It ships with Windows 11 Pro installed and a three-year warranty.

360mm liquid cooling with quiet fans

A 360mm quiet-edition AIO handles CPU heat while front and rear 140mm case fans run at 1500rpm and 30dBA each. The Thermaltake Toughpower 1000W 80 PLUS Gold power supply uses Japanese main capacitors and includes over-voltage, under-voltage, over-power and short-circuit protection. Together they keep thermals and noise controlled during sustained heavy loads.

ATX build with four M.2 slots and Thunderbolt 4

The TUF Gaming Z890-PLUS WiFi7 motherboard fits the Ceres 300 mid-tower case measuring 475 x 245 x 463 mm. It provides four M.2 connectors, four SATA 6Gbps ports and a front-panel USB 3.2 Gen 2 Type-C port. Rear I/O adds Thunderbolt 4 Type-C, USB 20Gbps Type-C, three USB 10Gbps and three USB 5Gbps ports. Internal drive bays accept one 3.5-inch or two 2.5-inch devices for future storage expansion.

Questions about this item

How is the 360 mm liquid cooler mounted to the LGA 1851 socket, and which step do builders often miss?

The cooler uses a 360 mm radiator with a dedicated LGA 1851 bracket; the step most often missed is removing the protective film from the cold-plate before seating it on the CPU.

What maintenance or replacement will the 1000 W 80 PLUS Gold PSU and 360 mm AIO need later?

The PSU fan may need dust cleaning or replacement after several years; the AIO is a sealed unit so only radiator fin cleaning is required — no coolant refill.

What limit appears first when the RTX 5080 16 GB and Core Ultra 9 285 K run sustained loads?

The 360 mm radiator surface area becomes the bottleneck — coolant temperature rises until fan speed hits 1500 rpm, then CPU clocks throttle to stay within thermal limits.
