Built for high-refresh gaming and heavy multitasking

This desktop pairs a 12-core Ryzen 9 9900X processor with an NVIDIA GeForce RTX 5070 graphics card carrying 12GB GDDR7 memory. The platform includes 64GB DDR5 RAM and a 4TB NVMe SSD for fast load times. It ships with Windows 11 Home installed and is ready for VR experiences.

240mm liquid cooler keeps thermals in check

An 850W power supply feeds the CPU and GPU while the closed-loop liquid cooler manages the 4.4GHz 12-core processor during typical gaming sessions. The system runs Wi-Fi and RGB lighting without extra cables. Component brands may vary across production batches.

Sustained loads stay stable on the 850W unit

The liquid cooler and power supply combine to maintain clock speeds during extended rendering or compile workloads rather than only short bursts. Four memory slots remain populated with the 64GB DDR5 kit, leaving no empty DIMM slots for future expansion. Buyers who want more storage or a second graphics card should plan around the existing configuration.

Questions about this item

How is the 240mm liquid cooler installed, and what step do people get wrong?

The 240mm liquid cooler comes pre-installed on the Ryzen 9 9900X inside the GT502 chassis; the step people miss is removing the shipping brackets that secure the radiator and pump before first boot.

What maintenance or replacement will the 240mm liquid cooler need later?

The sealed 240mm liquid cooler on the Ryzen 9 9900X requires no refilling; plan to replace the unit after several years if pump noise rises or CPU temperatures under load climb noticeably.

What limit shows up first under sustained use with the 850W power supply?

Under sustained loads the 850W power supply can become the limiting factor if combined CPU and GPU draw approaches its rated output, triggering protective shutdown.
