Workstation Desktop with 192GB DDR5

This Adamant Custom mid-tower desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. A 4TB Samsung 990 PRO NVMe drive and a 10TB hard drive provide high-capacity storage. The system runs Windows 11 Pro and includes a 240mm liquid CPU cooler in a black Antec P20 case.

Suited for Modelling Editing Rendering AI Learning

The 192GB memory ceiling and 12-core CPU serve professionals running large datasets, complex simulations or local AI workloads. Buyers who need more storage than the combined 14TB or who require ECC memory support should consider alternative configurations. The fixed 192GB maximum means no further RAM upgrades are possible.

192GB DDR5 Maximum Memory Supported

The motherboard supports a maximum of 192GB across four slots, and this build already populates that limit. If your workflow demands more system memory, this platform cannot accommodate it. Verify your application requirements against this hard ceiling before purchase.

Questions about this item

How is the 240mm liquid cooler installed on the AM5 socket, and what step do people often miss?

Mount the cooler on the motherboard before placing the board in the Antec P20 case, then connect the pump header and route the 120mm front fans to the fan headers; the step often missed is removing the protective film from the cold plate before seating it on the Ryzen 9 9900X3D.

What maintenance or replacement will the 240mm AIO and the 1200W Gold PSU need later?

The AIO is a sealed unit — no coolant refill is required; plan to replace the 140mm PSU fan and the three 120mm front case fans when noise or airflow drops, typically after several years of continuous use.

What thermal or power limit appears first when the Ryzen 9 9900X3D and RTX 5090 run sustained workloads?

The 240mm radiator surface area limits CPU heat dissipation before the 1200W PSU reaches its 80 PLUS Gold rating ceiling, so coolant temperature stabilises higher than the CPU boost algorithm prefers, capping all-core frequencies under prolonged load.
