Built for heavy workloads

This liquid-cooled mid-tower workstation pairs a twelve-core Ryzen 9 9900X3D with 128GB of DDR5 memory and a GeForce RTX 5070 graphics card. It ships with Windows 11 Pro and targets professionals who need sustained compute performance for rendering, simulation or AI-assisted workflows. The 850W 80 PLUS Bronze supply powers the complete platform.

128GB DDR5 across four slots

The motherboard populates all four DIMM slots with high-performance DDR5 modules, reaching the 128GB capacity listed. Maximum supported memory is 192GB, so no further expansion is possible without removing existing sticks. Buyers who need more than 128GB must plan a full kit replacement rather than a simple add-on.

240mm liquid CPU cooler and 140mm PSU fan

A 240mm quiet-edition AIO handles the processor while the power supply uses a 140mm fan rated for low noise. Three 120mm front case fans feed airflow through dust filters on bottom, front and top panels. This combination keeps thermals controlled under typical workstation loads without excessive acoustic output.

Questions about this item

What does the 12-core 4.4 GHz Ryzen 9 9900X3D deliver in a real workstation?

Twelve cores and 24 threads boost to 5.50 GHz with 128 MB L3 cache, so heavy renders and compiles finish noticeably faster than on lower-core chips.

How fast can the Samsung 990 PRO 4 TB NVMe actually move data through its PCIe 4.0 x4 link?

The drive is rated for 7450 MB/s reads and 6900 MB/s writes, and the motherboard’s four M.2 slots all support PCIe 4.0 x4 so the SSD can hit those speeds.

Will the 240 mm liquid cooler and RTX 5070 fit inside the Antec P20 mid-tower?

Yes — the case accepts 240 mm radiators and graphics cards up to the length of the RTX 5070, with three 120 mm front fans and dust filters on bottom, front and top.
