RTX 5090 Power Surge Linked to DLSS 5 in Enthusiast Testing

How DLSS 5 Affects Power Efficiency

An enthusiast claims that enabling DLSS 5 on the Nvidia RTX 5090 pushed power draw beyond 600 watts, causing the 16-pin power connector to melt during testing. The incident occurred in a high-performance gaming rig under sustained load, raising concerns about power delivery limits with next-gen neural rendering features.

The user reported that while running a demanding ray-traced benchmark with DLSS 5 activated, the GPU’s power consumption spiked sharply, exceeding the card’s rated TDP by a significant margin. Thermal sensors logged extreme heat buildup at the power connector, leading to visible deformation and melting of the plastic housing. The enthusiast shared images on a hardware forum showing the damaged connector, noting that the system shut down abruptly to prevent further damage. Nvidia has not officially commented on the incident, but the claim suggests that DLSS 5’s AI-driven frame generation may impose unexpected power demands under certain workloads.

Could This Happen Again?

DLSS 5 represents Nvidia’s latest advancement in neural rendering, using AI to generate additional frames and enhance image quality with lower native resolution rendering. While designed to improve performance per watt, early testing indicates that the computational load of the AI models can increase overall power draw when pushed to maximum settings. In this case, the combination of high frame rates, ray tracing, and DLSS 5’s frame generation appears to have created a power spike that overwhelmed the connector’s thermal tolerance. Experts note that while the 16-pin connector is rated for up to 600 watts, sustained operation near that limit can degrade materials over time, especially with inadequate cooling or poor cable seating.

The incident raises questions about whether power delivery standards need reevaluation as AI-enhanced graphics features become more prevalent. While most users are unlikely to encounter such extreme conditions, enthusiasts pushing hardware to its limits may face similar risks if power supplies, connectors, or cooling solutions are not adequately rated. Nvidia recommends using certified power supplies and ensuring secure connections when running high-end GPUs at peak performance. The company also advises monitoring power and temperature metrics during intensive workloads to prevent hardware stress.

What caused the RTX 5090’s 16-pin connector to melt? The enthusiast attributes the melting to a power draw exceeding 600 watts triggered by DLSS 5 during intense ray-traced testing, leading to overheating at the connector interface.

Frequently Asked Questions

Is DLSS 5 known to increase power consumption significantly? While DLSS 5 aims to improve efficiency, its AI processing can add to overall power load under maximum settings, particularly when combined with other demanding features like ray tracing and high frame rates.

How can users prevent similar issues with high-end GPUs? Using a high-quality, certified power supply, ensuring the 16-pin connector is fully seated, and monitoring system temperatures and power draw during heavy use can help mitigate risks.
