PCI-SIG tells members to ‘take all appropriate measures to ensure end user safety’ when making 12VHPWR cables

PCI-SIG shares public statement in response to recent lawsuit against NVIDIA.

The statement is short and goes straight to the point. The PCI-SIG specifications provide necessary technical information to proper design the 12VHPWR cables, says the group. The organization therefore washes its hands of any potential claims that the cable is improperly designed.

This statement refers to the ongoing lawsuit against NVIDIA “Genova v. NVIDIA Corporation”. This lawsuit claims that NVIDIA 16-pin cables pose a serious ‘electrical and fire hazard’.

PCI-SIG wishes to impress upon all Members that manufacture, market or sell PCI-SIG technologies (including 12VHPWR connections) of the need to take all appropriate and prudent measures to ensure end user safety, including testing for the reported problem cases involving consumers as alleged in the above-referenced lawsuit.

Members are reminded that PCI-SIG specifications provide necessary technical information for interoperability and do not attempt to address proper design, manufacturing methods, materials, safety testing, safety tolerances or workmanship. When implementing a PCI-SIG specification, Members are responsible for the design, manufacturing, and testing, including safety testing, of their products.


NVIDIA after confirming that only 50 cases of melting cables are thus far known to the company, provided a short guide how to properly install the new power adapter for GeForce RTX 40 series GPUs. It was reported that a potential hazard may occur when the cable is not fully plugged in. This was corroborated by comprehensive testing by GamersNexus.
