Workstation for AI and rendering

This desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU. It targets professionals who need local compute for AI learning, 3D modelling and video editing workloads. The 128GB DDR5 memory and fast storage support large datasets and complex scenes.

Liquid cooling with quiet fans

A 360mm AIO Quiet Edition cooler handles the CPU while case fans run at 1500rpm and 30dBA. The Thermaltake Toughpower 1200W 80 PLUS Gold PSU delivers stable power with Japanese capacitors and protection circuits. This combination keeps thermals and noise controlled during sustained heavy loads.

128GB DDR5 with 192GB maximum

Four slots are populated with high-performance DDR5 modules reaching 128GB total capacity. The motherboard supports up to 192GB for future expansion. Buyers who need more memory headroom than 128GB should verify the 192GB limit meets their workflow requirements.

Questions about this item

How do I install the 360mm AIO liquid cooler in the Ceres 300 case, and which step is often missed?

Mount the radiator on the front or top panel with the supplied fans, connect the pump header to the CPU_FAN socket on the Z890 motherboard, then plug the ARGB cable into the 5V header; the step most builders forget is removing the protective film from the cold-plate before seating it on the Core Ultra 9 285K.

What maintenance or replacement will the 360mm AIO and the 1200W PSU need later?

The AIO is a sealed loop so it only needs occasional dust removal from the 140mm radiator fans; the Thermaltake Toughpower 1200W 80 PLUS Gold PSU uses Japanese main capacitors rated for long life and requires no user-serviceable parts, just keep the intake filter clean.

What limit appears first when the RTX 5090 32GB and Core Ultra 9 285K run sustained heavy loads?

The 360mm Quiet Edition AIO sets the thermal ceiling; under continuous 24-core / 5.70 GHz boost the coolant temperature rises until the pump and fan curves hit their maximum, so GPU and CPU clocks will throttle together once the liquid loop saturates.
