Ryzen 7 9800X3D Gaming Desktop

This custom-built tower ships with an 8-core AMD Ryzen 7 9800X3D processor, liquid cooling, 32GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. Two 4TB Samsung 990 PRO SSDs provide 8TB of NVMe storage. Windows 11 Pro 64-bit comes pre-installed. The system is assembled in a CoolerMaster HAF 500 case with a 1200W 80 PLUS Gold power supply.

Ideal for 4K gaming and AI workloads

Buyers who need a ready-to-run workstation for high-refresh 4K gaming, local AI inference or content creation will match the CPU cache, GPU memory and fast storage. Users who require ECC memory, dual-GPU support or a smaller form factor should look at alternative configurations. The motherboard offers four memory slots for future expansion up to 192GB.

32GB RTX 5090 graphics card

The installed GeForce RTX 5090 carries 32GB of video memory on a PCI Express x16 interface. This single specification determines whether the system fits workloads that demand large frame buffers for 4K textures, 3D rendering or large-language-model inference. The card is powered by the included 1200W Gold-rated supply.

Questions about this item

How do I install the 240 mm liquid cooler on the AM5 motherboard, and what step do people miss?

Mount the cooler on the pre‑installed AM5 backplate, then tighten the four spring screws in a cross pattern until they stop; the step most people miss is removing the protective plastic film from the cold‑plate before seating it.

Which components will need replacement first under heavy gaming loads?

The 140 mm PSU fan and the three ARGB case fans (two 200 mm front, one 120 mm rear) are the only moving parts besides the pump; expect to replace a fan after several years of continuous operation.

What thermal limit appears first when the Ryzen 7 9800X3D runs at 5.20 GHz for long sessions?

The 240 mm radiator surface area becomes the bottleneck; coolant temperature rises until the pump‑fan curve hits its maximum, so CPU clocks will throttle before the 1200 W PSU or the 8 TB SSD reach any limit.
