A GALAX NVIDIA GeForce RTX 5080 graphics card has suffered a melted 16-pin power connector, causing system crashes during intensive use. The affected user reported on Reddit that the problem manifested as sudden black screens when launching games, while the system functioned normally during desktop or browser use.
The issue was discovered after the third display failure, revealing melted contacts on both the adapter and the graphics card connector. The user had been experimenting with local AI models and benchmarking DLSS 5, a new AI-powered technology that generates photorealistic rendering, putting maximum strain on the GPU.
Power supply compatibility
The system used a Cooler Master V850 power supply without ATX 3.0 support, requiring the included 16-pin adapter that became the source of critical overheating. Computer hardware repair experts note that random black screens under load while the PC remains idle indicate a loose connection in the 12V-2x6 connector.
Due to uneven current distribution across the individual cable wires, resistance increases at one of the contacts, leading to localized overheating and melting of the plastic.
User recommendations
Owners of GeForce RTX 50 series graphics cards are strongly advised to avoid using adapters with older power supplies and ensure the connector is tightly seated. Users should immediately inspect the connector at the first sign of game crashes to prevent potential damage or safety hazards.
