Built for modelling and AI workloads

This desktop pairs an 8-core AMD Ryzen 7 9800X3D with an Nvidia GeForce RTX 5090 32GB graphics card. Sixty-four gigabytes of DDR5 memory and a 2 TB Samsung 990 PRO NVMe drive give headroom for large datasets and video timelines. The system ships with Windows 11 Pro and a 240 mm liquid cooler on the CPU.

Straightforward setup with one cable catch

The Corsair 4000D case arrives assembled, so only power, display and peripherals need connecting. Rear I/O includes two USB4 40 Gbps Type-C ports, one USB 10 Gbps port, three USB 5 Gbps ports and four USB 2.0 ports. Builders should check GPU power cables are fully seated before first boot.

32 GB GPU memory decides fit for large models

The RTX 5090 provides 32 GB of video memory, which determines whether large language models or high-resolution render buffers fit entirely on the card. System memory can be expanded to 192 GB across four slots, and the motherboard offers four M.2 connectors for additional NVMe storage.
