Built for Professional Workloads

This Adamant Custom business desktop pairs an eight-core AMD Ryzen 7 9800X3D processor with 32GB of DDR5 memory and an Nvidia RTX A400 graphics card. The system targets engineers, designers and analysts who need reliable multi-threaded performance and professional driver support. Windows 11 Pro 64-bit is pre-installed and the platform is described as AI Ready.

Upgrading From Older Workstations

The jump makes sense when your current machine struggles with large datasets, complex 3D models or simultaneous virtual machines. The 2TB NVMe SSD delivers read speeds up to 7450 MB/sec and write speeds up to 6900 MB/sec, while the 10TB hard drive adds bulk capacity with a 256MB cache. The 96MB L3 cache on the CPU helps latency-sensitive tasks.

Straightforward Deployment

The workstation arrives assembled with a 240mm liquid cooler and an 850W 80 PLUS Bronze power supply already installed. The Antec P10 FLUX case includes sound-dampening panels and pre-fitted fans. Connect up to four displays via the MiniDP outputs on the GPU. The motherboard provides 2.5G Ethernet and Wi-Fi 7 connectivity. Buyers who need more than four video outputs or a different form factor should look elsewhere.

Questions about this item

What case clearance does the 240 mm liquid cooler need?

The Antec P10 FLUX mid-tower supports a 240 mm radiator at the front or top; the kit includes a 240 mm Quiet Edition AIO that fits those mounts.

How is the CPU cooler attached to the AM5 socket, and what step is often missed?

The AIO uses the standard AM5 back-plate and spring screws; the step often missed is removing the protective film from the cold-plate before tightening.

Which drive bays remain free for future storage upgrades?

The case provides three internal 3.5" bays and three 2.5" bays; one 3.5" bay holds the 10 TB HDD and one M.2 slot holds the 2 TB NVMe, leaving two 3.5" and three 2.5" bays plus three spare M.2 slots open.
