Do you trust companies to honor warranties that are not clearly defined in their official documentation?
PNY has refused a warranty claim for a melted RTX 5090 graphics card, citing the user's reliance on a power cable included with their ASRock power supply. The GPU owner reported the hardware failure while the card was idling, despite utilizing stock VBIOS and reduced power limits.
Why it matters
The dispute highlights growing consumer uncertainty regarding power cable compatibility for high-performance GPUs. PNY maintains that usage of third-party power cables invalidates coverage, a stance that has sparked debate over the clarity of manufacturer documentation.
The RTX 5090 GPU requires a 16-pin 12VHPWR power connector to function. The user attempted to power the card using a 12V-2x6 standard cable provided with an ASRock 1600G power supply.
The players
PNY

The Tech Race
This incident reflects the ongoing challenges in the power delivery ecosystem for high-end graphics cards as connector standards evolve. The shift toward higher wattage requirements continues to create friction between GPU manufacturers and independent power supply vendors.
Users should carefully verify if their power supply cables are explicitly approved by their GPU manufacturer to avoid potential warranty voids. This case suggests that relying on bundled PSU cables may lead to unexpected financial losses if hardware failures occur.
The takeaway
Consumers should cross-reference power cable compatibility lists provided by GPU manufacturers rather than assuming cross-brand utility. Always retain documentation and verify connector standards before installing high-draw components to protect your investment.
