12-core Ryzen 9 9900X3D workstation

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5080 graphics card. It ships with 64GB of DDR5 memory and 8TB of NVMe storage across two 4TB Samsung 990 PRO drives. A 240mm liquid cooler and 1000W 80 PLUS Gold power supply support sustained workloads.

Suits modelling, rendering and AI learning

The system targets professionals running modelling, video editing, rendering and AI learning tasks that benefit from high core counts and large local storage. It is not suited for buyers who need more than 64GB of memory out of the box or who require multiple additional internal drive bays beyond the two 3.5-inch and two 2.5-inch bays provided.

8TB NVMe storage in RAID-ready pair

The storage subsystem consists of two 4TB Samsung 990 PRO PCIe 4.0x4 NVMe SSDs delivering up to 7450 MB/s read and 6900 MB/s write speeds. This capacity and speed combination determines whether the workstation can hold active project files and scratch disks without external arrays.

Questions about this item

How do I install the 240mm AIO liquid cooler on the AM5 socket, and what step is commonly missed?

Mount the supplied AM5 bracket onto the motherboard back-plate, apply thermal paste, seat the cold-plate, then connect the pump header and the two 120mm radiator fans to the CPU_FAN and AIO_PUMP headers — forgetting the pump header leaves the cooler running at minimum speed.

Which components will need replacement first under heavy workloads?

The 140mm PSU fan and the three 120mm case fans are the only moving parts; expect to replace them after several years of continuous operation.

What thermal limit appears first when the Ryzen 9 9900X3D sustains 5.50 GHz on all 12 cores?

The 240mm radiator surface area becomes the bottleneck, so coolant temperature rises until the CPU hits its thermal ceiling and reduces boost frequency.
