Target User

This pre-built workstation pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU. It ships with 128GB DDR5 memory and 8TB of NVMe storage across two Samsung 990 PRO drives. Windows 11 Pro is installed. The platform suits professionals running local AI inference, complex 3D rendering pipelines or high-resolution video editing workloads.

Thermals and Power

A 360mm quiet-edition liquid cooler handles the CPU while a 1200W 80 PLUS Gold Thermaltake Toughpower unit feeds the full system. The case uses two 140mm PWM front fans behind tempered glass. Under typical creative loads the cooling loop and power supply operate within their low-noise design envelopes without throttling the processor or graphics card.

Upgrade Path

Four memory slots support up to 192GB DDR5 for larger datasets. Three M.2 connectors and internal 3.5-inch bays allow additional NVMe or SATA drives beyond the factory 8TB. Rear I/O includes USB4 Type-C, 2.5Gbps LAN and Wi-Fi 7 connectivity. Buyers needing multi-GPU compute or specialised accelerator cards should verify slot spacing and power-headroom before ordering.

Questions about this item

How is the 360 mm liquid cooler mounted on the LGA 1851 socket, and which step is most often missed?

The cooler uses the LGA 1851 bracket kit; the step most builders miss is removing the protective film from the cold-plate before tightening the four mounting screws.

Which component will need replacement first, and what capacity does the board support?

The DDR5 memory can be expanded later; the Z890M AORUS board supports up to 192 GB across four slots.

What thermal limit appears first during sustained 24-core workloads?

The 1200 W 80 PLUS Gold PSU and 360 mm AIO keep the CPU within its 5.70 GHz boost envelope, so the power limit is reached before thermal throttling.
