Built for SolidWorks workloads

This workstation pairs a 12-core Ryzen 9 9900X3D processor with 128GB of DDR5 memory and an NVIDIA RTX PRO 4000 Blackwell graphics card. The combination targets engineers and designers who run large assemblies, simulation studies or multi-tasking CAD sessions on Windows 11 Pro.

Storage layout and cooling

Two 4TB Samsung 990 PRO drives deliver 8TB of NVMe capacity with read speeds up to 7450 MB/s and write speeds up to 6900 MB/s. A 10TB hard drive adds bulk storage, while a 240mm liquid cooler keeps the CPU quiet under sustained loads.

Memory headroom and expandability

The board supports up to 192GB of DDR5, leaving room to double the installed 128GB if datasets grow. Four M.2 slots and multiple SATA ports allow further drive additions, though the 850W power supply sets a practical limit on how many high-power components can be added.

Questions about this item

How long will the 240 mm AIO liquid cooler and 850 W Bronze PSU last before they need replacement?

The 240 mm AIO uses a quiet-edition pump and a 140 mm fan; the 850 W 80 PLUS Bronze unit has Japanese main capacitors and over-voltage, under-voltage, over-power and short-circuit protection, both built for continuous workstation duty.

Which component hits its limit first during extended heavy rendering — the CPU thermal ceiling or the GPU 24 GB VRAM?

The Ryzen 9 9900X3D boosts to 5.50 GHz with 128 MB L3 cache under the 240 mm liquid cooler, while the RTX PRO 4000 Blackwell provides 24 GB VRAM; sustained loads will saturate GPU memory before the CPU thermal envelope is reached.

What are the noise and heat levels when the system runs all day with the liquid cooler and 140 mm PSU fan?

The 240 mm quiet-edition AIO and the PSU's ultra-quiet 140 mm fan are both specified for low noise; the case measures 490 x 239 x 486 mm and includes tempered-glass panels for controlled airflow.
