GoKawiilPNY rejects RTX 5090 warranty claim over use of PSU's own 12V-2x6 cable
A Redditor reports their PNY RTX 5090, bought last September, died last month after the 12VHPWR cable connectors melted on both the GPU and PSU ends. PNY denied the warranty claim the same day, saying only its own bundled cable or adapter is covered, even though the user used the cable that shipped with their Asrock PG-1600G PSU rather than a random third-party cable. The card was reportedly idling, unmodified, running stock settings and even underclocked when it failed.
GoKawiil's interpretation of the reporting above, not reported fact.
The case highlights how strict interpretations of GPU warranty terms could leave buyers unprotected even when using PSU-supplied cables rather than obviously non-approved third-party parts, especially as 12VHPWR/12V-2x6 melting incidents keep recurring across the industry. The user also notes PNY's stated policy doesn't clearly appear in its published warranty documentation, which could raise questions about consistency and transparency in how such claims are evaluated. If accurate, this could fuel broader consumer concern about who bears liability for a connector standard that has repeatedly shown thermal failures.
- A PNY RTX 5090 reportedly died with melted 12V-2x6 connectors on both card and PSU ends.
- PNY denied the warranty claim same-day, citing use of a non-PNY-branded cable despite it being the PSU's included cable.
- The user says PNY's cited justification isn't reflected in the company's published warranty policy document.
