Eight-core liquid-cooled workstation

This desktop pairs an eight-core AMD Ryzen 7 9700X with a 240 mm liquid cooler and 128 GB of DDR5 memory. The system targets creators and engineers who need sustained multi-thread throughput in a quiet chassis. Windows 11 Pro is pre-installed and the platform supports up to 192 GB of memory for future expansion.

4 TB NVMe plus 10 TB hard drive

The boot drive is a Samsung 990 PRO delivering up to 7 450 MB/s read and 6 900 MB/s write over PCIe 4.0 x4. A 10 TB hard drive with 256 MB cache adds deep capacity for archives and media libraries. Together the two volumes cover active projects and long-term storage without external enclosures.

RTX A400 four Mini DisplayPort outputs

The professional GPU provides four Mini DisplayPort connectors driving up to four 4K displays from a single card. Its 4 GB frame buffer suits 2D CAD, multi-monitor trading desks and video-wall playback but limits heavy 3D rendering or large GPU-compute workloads. The PCIe x16 link and 750 W power supply leave headroom for a larger card if the workflow demands it.

Questions about this item

Will the 4 TB Samsung 990 PRO NVMe and 10 TB HDD fit in my existing Antec P20 case if I move them over?

Yes. The Antec P20 mid-tower provides two internal 3.5"/2.5" bays and two 2.5" bays, so both the M.2 NVMe and the 3.5" hard drive can be installed without an adapter.

How do I confirm the 240 mm liquid cooler is keeping the Ryzen 7 9700X at its 5.50 GHz boost under load?

Monitor CPU temperature and clock speed in Windows Task Manager or HWMonitor while running a sustained workload; the 240 mm AIO should hold the 8-core processor near its 5.50 GHz maximum boost if airflow is adequate.

Which cables or adapters come in the box for the RTX A400 4x Mini DisplayPort outputs?

The system includes the RTX A400 with four Mini DisplayPort connectors; no Mini DP-to-DisplayPort or Mini DP-to-HDMI adapters are supplied, so purchase those separately for your monitors.
