Built for Modelling and AI Workloads

This workstation pairs a 12-core Ryzen 9 9900X3D with an RTX 5090 32GB GPU and 64GB DDR5 memory. It targets professionals running 3D modelling, video editing, rendering and AI learning tasks that demand high core counts and large frame buffers. The system ships with Windows 11 Pro and a 4TB NVMe drive for fast project access.

Installation Notes and Common Issues

The mid-tower case uses a 240mm liquid cooler and arrives fully assembled, so physical installation is limited to placing the unit and connecting peripherals. Builders should verify that the 1200W power supply cables are seated firmly after transit. The motherboard offers four memory slots with 192GB maximum support for future upgrades.

Deciding Specification: GPU Memory

The RTX 5090 provides 32GB of video memory, which determines whether the system can hold large models and textures in local VRAM. Workloads that exceed this capacity will fall back to system memory and lose performance. Buyers needing more GPU memory must consider a different graphics configuration.

Questions about this item

How can I confirm the Ryzen 9 9900X3D is reaching its 5.50 GHz boost clock under load?

Open Windows Task Manager or a monitoring tool like HWMonitor while running a demanding task; the CPU frequency column should show speeds approaching 5.50 GHz on active cores, and the 128 MB L3 cache will be reported in the cache details.

What components are included in the Cooler Master HAF 500 case and which common parts are not supplied?

The build ships with the X870 TUF motherboard, 12-core Ryzen 9 9900X3D, 240 mm liquid cooler, 64 GB DDR5, 4 TB Samsung 990 PRO SSD, RTX 5090 32 GB GPU, 1200 W Gold PSU, Wi-Fi 7, Windows 11 Pro, and pre-installed ARGB fans; no HDD, optical drive, or extra storage drives are included.

Should I choose the 64 GB DDR5 configuration or plan to expand toward the 192 GB maximum later?

The board provides four DDR5 slots with 64 GB installed; if current workloads fit within 64 GB, keep the configuration as-is and add matched modules later only if memory pressure appears in Task Manager.
