Custom-built workstation

This desktop pairs a twelve-core Ryzen 9 9900X3D processor with an RTX 5080 graphics card and 64 GB of DDR5 memory. It ships with Windows 11 Pro and targets professionals who need local compute for modelling, rendering and AI training workloads.

Sustained thermal behaviour

A 240 mm liquid cooler handles the CPU while the Antec P20 case moves air through three 120 mm front fans and dust filters. The 1000 W 80 PLUS Gold power supply delivers stable current during long render sessions without thermal throttling.

Storage and interface limits

Two 4 TB Samsung 990 PRO drives provide 8 TB of NVMe capacity with sequential reads up to 7450 MB/s and writes up to 6900 MB/s over PCIe 4.0. A 10 TB hard drive adds bulk storage, while the motherboard offers four M.2 slots and rear USB4 ports at 40 Gbps.
