Let's see if we can get this NVIDIA 4090 Cable to MELT! In the latest explorative video from JayzTwoCents, the creator dives deep into the controversial NVIDIA 4090 power cables, which have garnered attention due to reports of overheating and potential failure. With numerous instances of these cables melting, Jay decides it's time to replicate the conditions that may lead to such failures. This hands-on testing isn't merely for shock value; it's aimed at understanding the intricate conditions that could cause users' graphics cards to encounter catastrophic failures.

The Experiment Setup​

Jay outlines his testing procedure, acknowledging past concerns about these connectors and the risk of damage to expensive hardware. His goal is to clarify the typical user scenarios leading to failure and not just sensationalize the outcome. With the use of a FLIR thermal camera, he assesses the temperature of different cable configurations under load, emphasizing the importance of understanding the specs and load requirements of these new power connectors.

Key Findings and Observations​

1. Connector Design: The NVIDIA 4090 uses a novel 12-pin power connector that aims to streamline power delivery. However, its real-world application raises questions:
   • Many users lack sufficient dedicated power supply cables, which leads them to use pigtails that combine multiple power outputs. This can increase resistance and heat generation, potentially leading to failures.
   • The thermal gaps observed during initial tests suggested that under heavy loads, especially with unconventional bending or routing of cables, the connections could indeed become hazardous.
2. Heat Testing: Over the course of the testing, Jay mentions that despite pushing the GPU to its limits, he is unable to recreate a definitive failure scenario with the connectors used in a standard setup. This included:
   • Using both Corsair power supply cables and alternative custom cables from CableMod designed for safety and performance.
   • Observing temperature thresholds, which peaked around 55°C during stress tests—well within the safety margins generally expected for high-performance PC components.
3. Market Implications: With increasing discussions surrounding the reliability of NVIDIA’s connectors following reports from users facing issues, Jay notes that it’s likely more users will advocate for better options:
   • CableMod is highlighted as a potential go-to provider for upgraded cables that could alleviate some of the concerns surrounding the native connectors.
   • Jay hints at evolving industry standards as AMD may pivot away from this connector design, potentially leaving NVIDIA to stand alone with it.
     

     Recommendations for Users​

     In light of the findings, Jay makes several recommendations for PC enthusiasts using NVIDIA 4090 graphic cards:
     • Ensure Proper Use of Cables: Avoid pigtails when unnecessary. Use cables that adhere to the specifications required by high-performance components.
     • Consider Custom Solutions: Explore options like CableMod cables which provide better build quality and thermal management features.
     • Watch for Bends: Pay attention to cable routing and avoid tight bends that could create hotspots.

     Conclusion​

     By the end of the experiment, Jay concludes that while he couldn’t replicate a catastrophic failure with deliberate testing, there's still a need for caution among users. These cables, albeit robust under controlled circumstances, have shown themselves vulnerable in less than ideal setups. This mix of experimentation and community awareness underlines the significance of user feedback and documentation for manufacturers.
