A user reported a hardware failure on a PNY RTX 5090 graphics card while the system was idling. PNY denied the warranty claim, citing the use of a power cable included with an ASRock PG-1600G power supply rather than a company-approved cable.
Why it matters
This dispute highlights the ambiguity surrounding 16-pin power standards, as current documentation fails to explicitly restrict cable compatibility. Such conflicts create uncertainty for users managing high-power GPU configurations.
The incident involved the 12VHPWR power cable standard used on a 16-pin connector, while documentation for the GPU lacks specific instructions for 16-pin configurations, mentioning only 6-pin and 8-pin cables. The user reported using the stock VBIOS and reduced power limits.
The players
PNY
A manufacturer of graphics cards and storage hardware known for its line of Nvidia-based workstation and gaming GPUs.
ASRock
A hardware manufacturer specializing in motherboards, graphics cards, and power supplies for the enthusiast PC market.
The details
The failure occurred despite the user employing the cable bundled with an ASRock PG-1600G power supply. PNY maintains that only their approved power cables or adapters are eligible for coverage, though their February 28, 2025, warranty revision lacks a specific clause detailing this requirement. The 12VHPWR standard, a 16-pin connector capable of delivering high wattage, is a common source of physical thermal issues, often compared to the newer 12V-2x6 variant designed to improve connection robustness.

The Tech Race
The 12VHPWR power connector standard remains a focal point of industry-wide debates regarding thermal safety and manufacturer liability. This incident underscores the struggle for consensus between GPU vendors and power supply manufacturers over cross-brand cable compatibility.
Users should verify whether their graphics card manufacturer requires proprietary cables for warranty eligibility, as even standard-compliant cables may lead to claims being rejected. Until manufacturers update documentation to explicitly define compatible hardware, those using high-power GPUs should prioritize cables provided directly by the GPU vendor.
The takeaway
The lack of explicit cable compatibility requirements in current warranty documentation leaves users vulnerable to claims rejection during hardware failures. Users should monitor official PNY documentation updates for specific guidance on 12VHPWR cable requirements to ensure warranty compliance.
