A troubling new report has surfaced regarding NVIDIA’s flagship RTX 5090 GPU, where a Reddit user documented complete power connector failure using only manufacturer-supplied components. This incident raises fresh questions about the reliability of current power delivery systems for high-end graphics cards.
The Incident Details
The affected system was running an MSI GeForce RTX 5090 GAMING TRIO graphics card paired with a Corsair SF1000L power supply, which includes native ATX 3.1 compliant 12V-2×6 cabling. Despite following all recommended installation procedures and avoiding aftermarket cables or overclocking, the user discovered severe melting at both the GPU and PSU connection points. Photographic evidence shows significant plastic deformation and burnt wiring, suggesting temperatures exceeded safe operating limits.
Why This Case Stands Out
Several alarming factors make this particular failure noteworthy. First, the system used only certified components straight from the manufacturers – no third-party adapters or extensions were involved. Second, the power supply met the latest ATX 3.1 specification with the updated 12V-2×6 connector design that was supposed to prevent such issues. Third, the damage occurred during normal operation at stock settings in a relatively new system (just one month old). This suggests potential flaws in either the connector design itself or quality control during manufacturing.
Current Understanding of the Issue
Industry analysts note these failures remain relatively rare, with only five confirmed cases documented in the official Reddit tracking thread since the RTX 50 series launch. However, the random nature of occurrences makes identifying root causes difficult. Some theories being discussed include microscopic manufacturing variances in connector housings, thermal cycling fatigue in high-power scenarios, or possible current leakage across pins. NVIDIA and its partners have yet to issue any formal statements regarding these isolated incidents.

Protective Measures for Owners
For RTX 5090 owners concerned about potential connector issues, several precautionary steps are recommended. First, perform a thorough visual inspection of all power connections before installation, checking for any signs of imperfect molding or loose terminals. Second, consider using a digital thermal camera periodically to monitor connector temperatures during heavy workloads. Third, ensure your case has adequate airflow around the power input area of the graphics card. Some users report success with vertical GPU mounting configurations that may reduce mechanical stress on connections.
Broader Implications for the Industry
This latest failure continues an unfortunate trend of power delivery challenges in high-performance GPUs. While the percentage of affected units remains small, each publicized case damages consumer confidence in premium products. The situation puts pressure on both NVIDIA and power supply manufacturers to either revisit their connector designs or improve quality control measures. Some industry watchers suggest we may need a more fundamental redesign of high-wattage GPU power interfaces, possibly moving toward alternative connection methods better suited for 450W+ loads.

Next Steps for Affected Users
Owners experiencing similar issues face a complicated warranty process, as both the graphics card and power supply show damage in this case. Documenting the failure thoroughly with photographs and preserving all original packaging is crucial. While manufacturers will typically honor warranties for defective products, the determination of which component caused the failure may require technical investigation. Some users report better success dealing directly with the retailer for immediate replacement options rather than going through manufacturer RMA processes.
The PC hardware community continues monitoring these developments closely, hoping for either clearer guidance from manufacturers or design improvements in future production runs. For now, RTX 5090 owners are advised to remain vigilant about their systems’ power connections and thermal performance, especially during extended gaming or rendering sessions.
