Custom Ryzen 7 9800X3D Workstation

This custom desktop pairs an 8-core AMD Ryzen 7 9800X3D processor with an Nvidia GeForce RTX 5090 graphics card. The system includes 128GB DDR5 memory, a 4TB NVMe SSD and a 10TB HDD. It ships with Windows 11 Pro and uses a 240mm liquid cooler inside a mid-tower case.

Suited For Modelling And AI Workloads

The 96MB L3 cache and 32GB GPU memory help with large datasets, rendering and AI learning tasks. Four memory slots support up to 192GB total capacity. Builders who need more internal drive bays or a different form factor should look elsewhere.

Specification 4TB Samsung 990 PRO NVMe SSD

The boot drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s over a PCIe 4.0 x4 link. This speed reduces load times for heavy project files and operating system operations.

Questions about this item

What clearance does the 240 mm AIO liquid cooler need inside the CoolerMaster HAF 500 case?

The 240 mm radiator mounts in the HAF 500 with the front 200 mm ARGB fans; the case depth is 508 mm and width 203 mm, so the cooler fits without interfering with the 120 mm rear or GPU fans.

Which motherboard power connectors must be seated for the Ryzen 7 9800X3D and RTX 5090 before first boot?

Connect the 24-pin ATX and 8-pin EPS cables to the TUF X870-PLUS board, then attach the PCIe 12VHPWR or dual 8-pin leads from the 1200 W PSU to the RTX 5090; the GPU fan header on the rear 120 mm fan also needs power.

How often should the AIO coolant and the front 200 mm ARGB fans be inspected or replaced?

Check the 240 mm AIO for pump noise or coolant loss every 12–24 months; clean dust from the front 200 mm ARGB fans and rear 120 mm fans every 6 months to maintain airflow over the RTX 5090 and CPU radiator.
