Overview
The ASUS TUF-RTX5090-O32G-GAMING is a factory-overclocked graphics card featuring NVIDIA's GeForce RTX 5090 GPU and Blackwell architecture. Designed for demanding gaming, professional content creation, 3D rendering, and GPU-accelerated workloads, it combines 32 GB of GDDR7 video memory with PCIe 5.0 connectivity and ASUS TUF Gaming cooling and structural reinforcement.
The GPU includes 21,760 CUDA cores, a 512-bit memory interface, and 28 Gbps memory speed. Its boost clock reaches 2,550 MHz in default mode and 2,580 MHz in OC mode. NVIDIA RTX technologies provide hardware-accelerated ray tracing and AI-powered graphics capabilities in compatible games and professional applications.
Display connectivity includes two HDMI 2.1b ports and three DisplayPort 2.1b ports, supporting up to four simultaneous displays and a maximum digital resolution of 7680 × 4320. The triple-fan cooling system, ARGB lighting, and 3.6-slot design require sufficient chassis clearance, airflow, and power delivery.
This graphics card is suited to high-end gaming desktops and professional workstations requiring substantial video memory and GPU compute performance. ASUS recommends a 1000 W power supply for the complete system. Confirm case clearance, PSU compatibility, and the 16-pin GPU power connection before installation.

Product Note
ASUS recommends a 1000 W power supply based on a fully overclocked GPU and CPU system configuration. This is a whole-system recommendation, not the graphics card's standalone power consumption. Confirm PSU compatibility with the card's 16-pin power connector or supplied adapter, and follow the PSU manufacturer's installation and cable-routing instructions.
The card measures 348 × 146 × 72 mm and occupies 3.6 expansion slots. Check chassis clearance, adjacent expansion cards, airflow, and power-cable clearance before purchase. Actual performance varies by application, resolution, CPU, driver version, and graphics settings.
This OC model is distinct from the standard TUF-RTX5090-32G-GAMING, which has lower published boost-clock specifications.
