A warranty dispute involving the PNY RTX 5090 highlights a strict policy on power connectors that affects buyers using third-party cables. PNY denied a claim for a unit that suffered connector melting, citing the use of a non-approved 12VHPWR cable from an ASRock power supply. This ruling means users must verify their cable compatibility before installing high-end GPUs, as non-PNY components void coverage for connector damage.
PNY voids coverage for RTX 5090 units damaged by non-approved power cables
The incident centers on an RTX 5090 that failed while sitting idle with stock VBIOS and power limits. The owner reported that the GPU was not underclocked or overclocked, yet the 16-pin connector still melted. PNY stated that all their GPUs requiring a 12VHPWR input include a company-approved cable or adapter in the box. They emphasized that this specific cable is the only configuration covered under warranty.
PNY explicitly warned that damage caused by third-party power cables, adapters, or PSU cables falls under the responsibility of the manufacturer. This includes melting, burning, overheating, or deformation of the connector. The company clarified that such damage is not covered by their warranty program. Users relying on existing PSU cables from other brands face a significant risk if those cables do not meet PNY's approval standards.
The owner found no mention of this cable requirement in the printed warranty documentation, specifically the version dated February 28, 2025. This discrepancy between the verbal policy and the printed guide has raised concerns among users. We have been tracking RTX 5090 closely, including earlier reports on warranty issues with other models. Buyers should carefully review their power supply cables to ensure they match the approved configurations listed by the GPU manufacturer.
