Core specification

This desktop pairs a twelve-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card carrying 32GB of video memory. Sixty-four gigabytes of DDR5 system memory and a 1TB NVMe solid-state drive provide fast throughput for modelling, editing, rendering and AI learning workloads. A secondary 10TB hard drive adds deep capacity for project archives and media libraries. The system ships with Windows 11 Pro installed.

Included hardware impact

A 240mm liquid cooler keeps the CPU at stable temperatures during sustained compute tasks. The motherboard supplies rear USB4 ports at 40Gbps, multiple 10Gbps and 5Gbps USB connections, Intel 2.5Gb Ethernet and Wi-Fi 7 wireless. Internal headers add further USB and SATA expansion. Realtek 7.1 surround audio handles monitoring without an external interface. The 1200W 80 PLUS Gold power unit delivers protected, efficient power to every component.

Build and connectivity practicalities

The tempered-glass chassis measures 447mm deep, 215mm wide and 469mm high in black. Two 140mm PWM front fans feed airflow to the liquid radiator and GPU. Front-panel I/O includes a USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and dual audio jacks. Inside, two 3.5-inch and two 2.5-inch bays remain free for future storage upgrades. Four memory slots support up to 192GB total DDR5.

Questions about this item

When will the 240 mm liquid cooler need its coolant checked or the pump replaced?

The 240 mm Quiet Edition AIO is a sealed unit; no coolant top-ups are required. Pump life varies with load, so monitor CPU temperatures and replace the cooler if temps rise unexpectedly.

Which component hits its thermal ceiling first during an all-day render — the 12-core Ryzen 9 9900X3D or the RTX 5090?

Both parts share the case airflow. The CPU is cooled by a 240 mm AIO while the RTX 5090 uses its own triple-fan design; sustained loads will push GPU thermals up faster because it draws more power.

How loud does the system get when the 1200 W Gold PSU, 240 mm AIO and GPU fans run at full tilt for hours?

The PSU uses a 140 mm ultra-quiet fan, the AIO is a Quiet Edition model, and the RTX 5090 has a triple-fan cooler. Expect a noticeable but not intrusive hum under continuous maximum load.
