Built for Modelling, Editing and AI

This desktop combines a 12-core Ryzen 9 9900X3D processor with 128GB DDR5 memory and an RTX 5090 graphics card. The configuration targets professionals who need high parallel throughput for 3D rendering, video timelines and machine-learning workloads. Windows 11 Pro is pre-installed on a 2TB NVMe drive.

Liquid CPU Cooler and 1200W Gold PSU

A 240mm quiet-edition liquid cooler handles the CPU thermal load while a 140mm fan on the 1200W 80 PLUS Gold power supply runs at low noise. The case provides front-panel USB 3.2 Type-C and audio connections for daily convenience. Internal bays allow two 3.5-inch and two 2.5-inch drives if more local storage is required.

32GB VRAM on the RTX 5090 Decides Fit

The graphics card carries 32GB of video memory, which is the single figure that determines whether large scenes, high-resolution textures or big model weights fit entirely on the GPU. Buyers who need more VRAM for larger datasets cannot expand it on this card. The motherboard supports up to 192GB system memory across four slots if workloads demand more RAM.

Questions about this item

How is the 240 mm AIO liquid cooler mounted on the AM5 socket, and what step do builders often miss?

The cooler uses the standard AM5 retention frame; the step many miss is removing the protective film from the cold-plate before seating it on the Ryzen 9 9900X3D.

Which component will need attention first — the AIO pump, the 140 mm PSU fan, or the case fans — and roughly when?

The AIO pump is the first wear item; expect to plan a replacement around the 3-to-5-year mark under heavy daily loads.

What thermal or power limit appears first when the Ryzen 9 9900X3D and RTX 5090 run sustained workloads?

The 240 mm radiator reaches its heat-dissipation ceiling before the 1200 W PSU or the CPU's own boost algorithm throttles.
