ASUS TUF GT502 Ryzen 9 9900X3D RTX 5080 128GB DDR5 4TB NVMe liquid-cooled 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 at 4.4GHz and an NVIDIA GeForce RTX 5080 graphics card with 16GB GDDR7 memory. It includes 128GB of DDR5 RAM across four slots and a 4TB NVMe SSD. The system ships with Windows 11 Home installed and a 240mm liquid cooler for the CPU. It targets players who want a ready-to-use high-performance machine without assembling parts themselves.

Sustained load with 240mm liquid cooling

The 240mm liquid cooler handles heat from the 12-core Ryzen 9 9900X3D during extended sessions, while the 1000W power supply feeds both the CPU and the RTX 5080 under continuous demand. The GT502 chassis airflow moves warm air away from the GPU and memory, helping maintain stable clocks over long periods. Builders who need a second graphics card or more internal drive bays should look elsewhere, as the supplied configuration fills the primary PCIe x16 slot and the single 4TB NVMe is the only storage device listed.

Check case clearance and power headroom

Verify that your workspace accommodates the GT502 footprint and that the 1000W unit matches your local mains voltage. The four DDR5 slots are fully populated, so future memory upgrades require replacing existing modules. The RTX 5080 occupies the sole PCI Express x16 connection, leaving no room for additional expansion cards. No other storage drives are included, so plan for external or network storage if 4TB proves insufficient.
