Thermaltake T6WT-X870-590-LCS gaming PC Ryzen 7 9800X3D RTX 5090 32GB DDR5 2TB SSD

Ready-to-game desktop

The Thermaltake LCGS Reactor 9890S ships assembled with an AMD Ryzen 7 9800X3D processor, 32GB DDR5 memory and an NVIDIA GeForce RTX 5090 graphics card. A 2TB NVMe SSD and Windows 11 Home are installed. A 360mm ARGB liquid cooler and a 1200W 80Plus Gold ATX 3.0 power supply handle thermals and power. The white chassis includes Wi-Fi 7 and Gigabit Ethernet.

Suits high-refresh 4K players, not budget builds

This system targets enthusiasts who want maximum frame rates in modern titles and workloads that benefit from 32GB GDDR7 video memory. The eight-core CPU with 96MB L3 cache supports 128GB maximum memory for future upgrades. Buyers who need more storage or a smaller footprint should look at other configurations. The fixed component selection also limits customisation for specialised workflows.

Fits a full-tower build with room to expand

The ATX 3.0 power supply delivers 1200W through native 12VHPWR connectors for the RTX 5090. Four DDR5 slots allow expansion to 128GB at 6000MT/s. The X870 chipset provides PCIe 5.0 lanes for additional NVMe drives and high-speed add-in cards. Front-panel USB and audio headers remain accessible for peripherals. The 360mm radiator requires a case with matching top or front mounting points.
