Core Configuration

This Adamant Custom gaming desktop pairs a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card. The system includes 192GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe solid-state drive. A 360mm liquid cooler and a 1200W 80 PLUS Gold power supply support the high-performance components inside a Cooler Master HAF 500 mid-tower case.

Target Builder

The workstation suits professionals who need large memory capacity for rendering, modelling or AI learning workloads alongside high-end gaming performance. The four occupied memory slots leave no room for future RAM upgrades. Buyers who anticipate expanding memory beyond 192GB or who require additional internal drive bays beyond the two 3.5-inch and two 2.5-inch slots should consider alternative platforms.

Deciding Specification

The 192GB DDR5 memory capacity is the defining attribute that determines whether this system matches the workload. With all four slots populated at the maximum supported limit, the configuration is fixed for the life of the build. Buyers who need more memory or who plan to scale RAM later cannot do so on this motherboard.

Questions about this item

Will the 1200 W PSU handle the i9-14900K and RTX 5090 under sustained full load?

The Thermaltake Toughpower 1200 W 80 PLUS Gold unit is rated for continuous delivery at that wattage, matching the combined peak draw of the 24-core CPU and 32 GB GPU.

How loud is the 360 mm liquid cooler and case fans during an all-day render?

The Quiet Edition 360 mm AIO and 140 mm PSU fan are specified as ultra-quiet; front 200 mm ARGB fans move high volume at low RPM for steady thermal performance.

Does the 192 GB DDR5 kit fill every slot on the Z790 AORUS board?

Yes — four modules populate all four DDR5 slots, reaching the board’s 192 GB maximum.
