NVIDIA’s latest flagship GPU, the RTX 5090, is making headlines not just for its cutting-edge performance but also for an issue that has haunted its predecessor—the problem of melting power connectors. Some early adopters of the $2,000 graphics card have reported concerns about their power cables burning or melting, raising fears of a repeat of the controversy that surrounded the RTX 4090.
Back in 2022, the RTX 4090 faced a similar issue, where users reported that the 16-pin 12VHPWR connectors were overheating, leading to melted plastic, damaged GPUs, and, in extreme cases, small fires. NVIDIA acknowledged the problem and later attributed it to improper cable connections, but many users and independent reviewers questioned whether the connector design itself was flawed.
Now, with the release of the RTX 5090, some buyers are experiencing the same issue, prompting concerns about whether NVIDIA and its partners have truly addressed the root cause. The RTX 5090, which features DLSS 4, multi-frame generation, and a significant boost in performance over its predecessor, still relies on high power consumption, requiring the 12VHPWR connector. Given the previous history, users were already wary, and these early reports of melting cables have reignited the controversy.
At this stage, it is unclear whether the melting power connectors are the result of a few defective units or a widespread design flaw. Some experts believe that improper installation could still be a major factor, as the 12VHPWR connector requires a firm and secure connection to avoid overheating. However, with multiple reports surfacing just weeks after launch, the issue could point to something more significant.
NVIDIA has yet to release an official statement addressing these complaints, but if the pattern follows what happened with the RTX 4090, the company may soon investigate and issue guidance for users. The RTX 4090’s power cable problem led to lawsuits, debates over PCIe power standards, and even a redesign of third-party power connectors. If the RTX 5090 suffers from a similar fate, NVIDIA may face yet another wave of criticism.
For now, users who have purchased the RTX 5090 are advised to double-check their power connections and monitor for any signs of overheating. As more information emerges, NVIDIA will likely need to act fast to avoid another PR disaster surrounding its flagship product.
