A PNY RTX 5090 owner says the company refused to honor a warranty claim after the card’s bundled power cable melted during normal use, and then closed the customer’s support ticket rather than explain the decision. The complaint, first shared on Reddit’s r/technology forum this week, has drawn thousands of upvotes and reignited scrutiny of Nvidia’s 12V-2×6 power connector, which has been linked to overheating incidents since the RTX 40-series launch in 2022.

What Happened
According to the original poster, the melting occurred on the PNY-supplied native power cable connected to an RTX 5090 Founders Edition-style card, not a third-party adapter. Photos included in the thread show discoloration and deformation around the connector housing, consistent with excessive heat buildup at the pin contacts. The user says PNY’s support team initially requested photos and proof of purchase, standard steps for a warranty review, but ultimately denied the claim without a detailed technical explanation.
When the customer pushed back and asked PNY to clarify what evidence would have satisfied the review, the company allegedly closed the support ticket outright, cutting off further correspondence. Screenshots of the exchange, which the poster says are unedited, show a support representative citing unspecified “misuse” language in the warranty terms before ending the conversation.
“I used the cable that came in the box, in the way it was designed to be used, and now I’m being told it’s my fault,” the original poster wrote, according to the widely circulated thread.
A Recurring Problem for High-Wattage GPUs
The RTX 5090, Nvidia’s current flagship consumer graphics card, draws significantly more power than previous generations, placing heavy demand on the 12V-2×6 connector standard (an updated version of the earlier 12VHPWR design). Reports of melting connectors and cables have persisted since the RTX 4090 launched in late 2022, with independent testers and enthusiast outlets documenting cases where uneven load distribution across the connector’s pins caused localized overheating.
Nvidia revised the connector specification once already in response to those complaints, adding design tolerances intended to reduce the risk of partial insertion, a common culprit identified in early failure investigations. However, the RTX 50-series’ higher power ceiling appears to have kept the underlying risk in play, according to posts from PC hardware communities and repair forums tracking similar incidents throughout 2026.
Warranty Policies Under the Microscope
The dispute highlights a broader tension between GPU manufacturers and consumers when hardware failures may stem from a component design rather than user error. Board partners like PNY, Asus, MSI, and Gigabyte typically handle their own warranty support independently of Nvidia, meaning claim outcomes can vary widely depending on which brand’s card a customer purchased, even though the underlying connector technology is licensed from Nvidia across the industry.
Consumer advocates who have followed the 12V-2×6 melting reports argue that closing a support ticket without a clear technical rationale undermines trust in the review process, particularly when the failure involves a component the manufacturer itself supplied. PNY has not issued a public statement addressing this specific case at the time of writing, and the company did not immediately respond to requests for comment cited in the original discussion thread.
What Affected Users Can Do
Hardware repair specialists recommend that GPU owners experiencing similar issues take the following steps before contacting a manufacturer:
- Photograph the connector, cable, and card immediately after noticing damage, including close-ups of any discoloration or deformation.
- Retain the original packaging, receipt, and any correspondence with support staff.
- Request a written explanation if a claim is denied, and escalate to a supervisor or the manufacturer’s corporate customer relations team if the first response is unsatisfactory.
- File a complaint with a local consumer protection agency if a warranty dispute cannot be resolved directly.
The incident arrives amid growing consumer frustration with automated or opaque support processes across the tech industry, a theme also explored in a recent report on personal AI agent horror stories, where users described similar difficulty getting clear answers from company support channels.
Looking Ahead
Until Nvidia or its partners implement a more robust connector standard, or until board makers adopt more transparent failure-review processes, incidents like this one are likely to keep surfacing on enthusiast forums. For now, the RTX 5090 owner’s experience serves as a cautionary example for anyone running Nvidia’s highest-wattage graphics cards: keep documentation ready, and be prepared to push back if a warranty claim is denied without explanation.
