ASUS TUF GT502 Liquid Cooled Ryzen 9 9900X3D RTX 5090 128GB DDR5 4TB NVMe Gaming PC

ASUS TUF GT502 Liquid Cooled Desktop

The ASUS TUF GT502 is a pre-built gaming desktop powered by an AMD Ryzen 9 9900X3D 12-core processor running at 4.4GHz. It pairs that CPU with an NVIDIA GeForce RTX 5090 graphics card holding 32GB GDDR7 memory. The system includes 128GB DDR5 RAM and a 4TB NVMe SSD. Windows 11 Home comes installed and the unit is liquid cooled with a 240mm radiator. It targets enthusiasts who want a ready-to-play machine for 4K gaming and heavy content creation.

1200W PSU and Factory Assembly Benefits

A 1200W power supply drives the high-end components without requiring a separate purchase or cable management effort. The 240mm liquid cooler arrives pre-filled and mounted, removing the risk of installation leaks or uneven thermal paste application. WiFi and RGB lighting are integrated into the chassis, so no extra adapters or controllers are needed. The PC ships tested, so first boot goes straight to the desktop instead of a troubleshooting session.

AM5 Platform and Memory Constraints

The motherboard uses the AM5 socket with four DDR5 slots, all populated to reach 128GB. Buyers planning future memory upgrades must replace existing modules rather than add to empty slots. The 4TB NVMe drive occupies one M.2 slot; additional storage requires verifying spare M.2 or 2.5-inch bays inside the GT502 case. Component brands may vary from the images shown, so confirm exact part numbers if specific vendor firmware matters to your workflow.
