Built for rendering, modelling and AI learning

This desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU, 64GB DDR5 memory, a 2TB NVMe SSD and a 10TB HDD. Windows 11 Pro runs on a Gigabyte Z890M Aorus motherboard cooled by a 360mm liquid cooler. It targets creators who need GPU memory and multi-core throughput for heavy workloads.

Suits studios that need 32GB VRAM

The four memory slots allow expansion to 192GB, so buyers who want more RAM later can add it. Builders who need a smaller chassis, a lower power draw or a system without liquid cooling should look elsewhere. The 1200W power supply and 447mm depth require adequate space and electrical capacity.

The deciding spec is the RTX 5090 with 32GB VRAM

That frame buffer lets the machine hold large models and textures in GPU memory instead of swapping to system RAM. If your workflow fits in less VRAM, a card with less memory will cost less and draw less power.

Questions about this item

What are the case dimensions and drive-bay layout for the Adamant Custom Intel Core Ultra 9 285K RTX 5090 system?

The chassis measures 447 mm deep, 215 mm wide and 469 mm high. Inside there are two 3.5-inch bays and two 2.5-inch bays for additional storage.

How is the 360 mm liquid cooler mounted, and what step do builders often miss?

The 360 mm AIO radiator fits the front or top of the case with three 140 mm fans. The step people miss is removing the protective film from the cold-plate before seating it on the LGA 1851 CPU.

When will the 1200 W 80 PLUS Gold PSU or the 140 mm case fans need replacement?

The PSU uses Japanese main capacitors rated for long life; expect ten-plus years under normal loads. The 140 mm PWM fans should be cleaned yearly and swapped if bearing noise appears after five to seven years.
