Custom Ryzen 9 9900X3D Gaming Desktop

This liquid-cooled desktop PC ships with a 12-core AMD Ryzen 9 9900X3D processor, 64GB of DDR5 memory and a 2TB NVMe SSD. It runs Windows 11 Pro and uses integrated Radeon graphics for display output. The system is built for users who want a ready-to-run workstation or gaming rig without adding a discrete card.

Ideal for CPU-heavy workloads

Buyers who need high frame rates at 1440p or 4K, or who rely on hardware ray-tracing acceleration, should look at a system with a dedicated graphics card. The integrated GPU also limits multi-monitor setups beyond the available HDMI and USB4 ports.

12-core Ryzen 9 9900X3D with 128 MB L3 cache

The processor provides 12 cores and 24 threads with a 4.3 GHz base clock and up to 5.50 GHz boost. Its large 128 MB L3 cache is the key spec that drives gaming and compilation performance on this platform.

Questions about this item

What USB standard do the rear USB4 ports use, and what is their maximum throughput?

The motherboard provides two rear USB4 ports, each rated at 40 Gbps.

What are the case dimensions and which motherboard form factor does it support?

The chassis measures 447 mm deep, 215 mm wide and 469 mm high and fits an ATX board.

How is the CPU cooler mounted, and which step is often missed?

The 360 mm AIO radiator screws to the case fan mounts; the pump block then fastens to the AM5 socket using the supplied back-plate and standoffs — forgetting the back-plate is the common error.
