Built for heavy creative workloads

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU, 128GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe drive plus a 10TB hard drive. It targets professionals who need sustained multi-threaded compute for rendering, modelling and AI learning tasks in a single Windows 11 Pro system.

Liquid cooling keeps the CPU quiet under load

A 360mm quiet-edition AIO handles the processor while the Ceres 300 case moves air through three 140mm fans rated at 1500rpm and 30dBA each. The Thermaltake Toughpower 1200W 80 PLUS Gold PSU supplies power with Japanese capacitors and protections for over-voltage, under-voltage, over-power and short-circuit conditions.

128GB DDR5 across four slots is the capacity ceiling

The Z890 TUF motherboard populates all four DIMM slots with high-performance DDR5, leaving no free slots for expansion. Maximum supported memory is 192GB, so any future increase requires replacing the existing kit rather than adding modules.

Questions about this item

How is the 360mm liquid CPU cooler installed, and which step do builders often miss?

The cooler mounts on the LGA 1851 socket with the included bracket; the step often missed is removing the protective film from the cold-plate before securing the pump block.

What maintenance or replacement will the 128GB DDR5 memory need later?

DDR5 modules have no user-serviceable parts; if capacity becomes limiting, the board supports up to 192GB across four slots, so additional sticks can be added without removing the original kit.

What limit appears first when the RTX 5090 32GB runs sustained heavy workloads?

The 1200W 80 PLUS Gold PSU sets the power ceiling; the GPU and 24-core CPU together can draw close to that rating, so total system power becomes the limiting factor before thermal throttling.
