Built for modelling, rendering and AI learning

This workstation pairs a twelve-core Ryzen 9 9900X3D with 128GB DDR5 and a GeForce RTX 5090 32GB to handle large scene files, video timelines and training datasets in a single tower. The 8TB NVMe array is split across two Samsung 990 PRO drives for fast project loading. Liquid cooling keeps the CPU stable during long sessions.

Sustained load behaviour

The 240mm liquid cooler and 1200W Gold-rated power supply are sized for continuous all-core workloads rather than brief bursts. Rear-panel USB4 at 40Gbps and Intel 2.5Gb Ethernet maintain throughput when moving multi-gigabyte assets between storage and network. Wi-Fi 7 adds a wireless fallback without interrupting wired transfers.

128GB DDR5 decides fit

Memory capacity is the limiting factor for simultaneous virtual machines, GPU-accelerated render buffers and in-memory datasets. The board supports up to 192GB across four slots, so the current 128GB configuration leaves room to grow. Buyers who need more storage than 8TB or a second graphics card should look elsewhere.

Questions about this item

How loud does the 240mm AIO liquid cooler get under sustained load?

The 240mm Quiet Edition liquid cooler uses a low-noise pump and radiator fans designed to keep acoustic levels minimal even when the 12-core CPU runs at its 5.50 GHz boost for long sessions.

Does the 1200W 80 PLUS Gold PSU include the 12V-2x6 cable required by the RTX 5090?

Yes, the Thermaltake Toughpower 1200W unit ships with the native 12V-2x6 connector that the GeForce RTX 5090 32GB needs, so no adapter is necessary.

Will my existing SATA SSDs and hard drives work with the PRIME X870-P motherboard?

The board provides two SATA 6Gb/s ports, so up to two legacy SATA drives can be connected directly without extra controllers.
