Overview
The ASUS TUF-RTX5080-O16G-GAMING is a factory-overclocked graphics card featuring NVIDIA's GeForce RTX 5080 GPU and Blackwell architecture. Designed for high-performance gaming, content creation, and GPU-accelerated workloads, it combines 16 GB of GDDR7 video memory, PCIe 5.0 connectivity, and ASUS TUF Gaming cooling and structural reinforcement.
The card features 10,752 CUDA cores, a 256-bit memory interface, and 30 Gbps memory speed. Its boost clock reaches 2,700 MHz in default mode and 2,730 MHz in OC mode. NVIDIA RTX technologies provide hardware-accelerated ray tracing and AI-powered graphics capabilities, including DLSS features in supported games and applications.
Display connectivity includes two HDMI 2.1b ports and three DisplayPort 2.1b ports, supporting up to four simultaneous displays. The triple-fan cooling system, ARGB lighting, and 3.6-slot design require adequate case clearance and airflow.
This graphics card is suitable for high-end gaming desktops, creative workstations, and GPU-intensive applications. ASUS recommends an 850 W power supply for the complete system. Verify chassis dimensions, PSU compatibility, and the required 16-pin power connection before installation.
