GoKawiilPNY denies RTX 5090 warranty claim over melted native PSU cable
A Reddit user reported that his GeForce RTX 5090 stopped working after the 12V-2x6 connectors melted on both ends of the modular cable bundled with his ASRock 1600W power supply. He says the card was running stock BIOS settings with a reduced power limit and was idle when the failure occurred, yet PNY denied his warranty claim within a day, citing use of a non-PNY-approved cable.
GoKawiil's interpretation of the reporting above, not reported fact.
The case highlights ongoing concerns about the reliability of the 12V-2x6/12VHPWR connector standard used on high-end Nvidia GPUs, which has been linked to repeated melting incidents. It also raises questions about whether manufacturers can void warranties over third-party cables when their own written terms, according to the user, only reference following installation instructions rather than specifying approved cables explicitly.
- An RTX 5090 owner reported melted connectors on both ends of his power supply's native cable.
- PNY reportedly rejected the warranty claim, citing use of a non-PNY-approved cable rather than the included one.
- The user says PNY's written warranty terms do not explicitly restrict cable types, only referencing installation guide compliance.
