Across Western tech circles, reports have grown about a troubling issue with the RTX 4090 graphics cards. A user who purchased an assembled PC from CyberPowerPC found that the 12VHPWR power connector on the card overheated and melted. Interestingly, the buyer did not open the system case or modify anything; instead, he contacted the service center right away to flag the problem.
At the moment, CyberPowerPC has not issued a public statement addressing the incident. This is not the first time the problem has surfaced. Earlier, a Reddit user who owns a Gigabyte GeForce RTX 4090 Gaming OC card shared a similar melting connector experience while playing Red Dead Redemption 2. The thread underscored that intense gaming sessions could stress the power coupling enough to cause damage over time.
In another Reddit post, a different user described a comparable failure with an ASUS TUF Gaming GeForce RTX 4090 OC Edition card. The recurring nature of these anecdotes has drawn attention from the broader hardware community and sparked ongoing discussions about reliability and safety in high-powered graphics setups.
NVIDIA has acknowledged the reports and confirmed that an inquiry is underway, though no definitive findings have been released yet. The conversation in the forums has also highlighted how the public version of the power delivery system relies on a proprietary adapter included with the graphics card, rather than standard cables. This distinction has led some users to question whether the adapter design or its compatibility with certain power supplies could be a contributing factor to the failures observed in several instances.
Industry observers and reviewers have noted that while NVIDIA does not place extra restrictions on power supplies, the official guidance emphasizes using the provided adapters and ensuring a secure, manufacturer-approved connection. The situation has prompted many builders to reexamine their cooling setups, power provisioning, and cable management to reduce stress on the connector and improve overall stability during demanding workloads.
Consumer safety advocates suggest that anyone experiencing similar symptoms should stop using the system immediately, disconnect power, and seek service through the original vendor or a qualified technician. While the incidents appear isolated, they raise important questions about the durability of high-end GPUs under real-world conditions and the role of connectors in maintaining long-term reliability for premium gaming rigs. Ongoing updates from NVIDIA and longtime hardware partners are expected as more data becomes available. Cited: VG Times and user discussions on major community boards.
As the investigation progresses, enthusiasts are urged to monitor official notices and avoid hastily replacing components without professional diagnostics. The situation serves as a reminder that premium graphics cards demand careful pairing with reliable power delivery and thoughtful system design, especially in configurations that push performance to the edge.
