A GeForce RTX 5090 12V-2x6 power cable reportedly melted during testing on an MSI GeForce RTX 5090 Gaming Trio OC, with smoke observed and the cable fused to the card. The GPU still functioned in Windows, but FurMark and thermal imaging showed external contact overheating, and the NZXT C1500 PSU cable was also severely damaged. PCMasters.de has contacted MSI seeking repair or replacement, highlighting ongoing safety concerns around high-power connectors on flagship GPUs.
The immediate market impact is not on the GPU vendor alone but on the broader premium PC ecosystem: repeated connector failures raise the perceived reliability risk of next-gen power delivery across PSU, cable, chassis, and board suppliers. That shifts buying behavior toward products with simpler or overengineered power paths, which can benefit legacy 8-pin solutions, high-end PSUs with stronger warranties, and third-party cooling/accessory vendors that can market safety and thermal monitoring. The second-order risk is reputational compounding. If a small number of visible incidents become a pattern, the issue can depress early-adopter demand for flagship GPUs for 1-2 product cycles, especially among enthusiasts who are also the highest-margin customer cohort. The bigger concern is not unit replacement cost, but channel hesitation: retailers may de-emphasize bundles, integrators may widen qualification standards, and reviewers will likely keep amplifying failure modes, extending the headline cycle for weeks to months. Contrarian view: this may be more of a design-validation and public-perception problem than an immediate demand collapse. Most buyers of ultra-high-end GPUs are less price-sensitive and may accept workaround behavior if the performance delta remains compelling, so the downside is likely concentrated in launch momentum rather than full-cycle sell-through. The tradeable angle is in volatility and relative underperformance of adjacent hardware names exposed to enthusiast build sentiment, not in a broad sector repricing. For MYSZ, the direct read-through is limited, but any sustained increase in hardware safety anxiety can modestly support software-led PC monitoring and diagnostics narratives if management can position the product as a risk-management tool rather than a utility. The key catalyst window is the next 2-6 weeks as more user reports, vendor responses, or recall-style language could either validate the problem or contain it.
