Shortly after the release of GeForce RTX 4090 video cards, some buyers faced reflow of power connectors 12VHPWR. Now, the PCI-SIG organization responsible for standardizing devices using the PCI interface, including specifications for power connectors, has released an official comment on this situation. In fact, the organization declined responsibility, noting that the video card manufacturers themselves are to blame for everything, while the connector itself has nothing to do with it.

PCI-SIG urged manufacturers of products with 12+4 pin (12VHPWR) connectors to ensure maximum safety for users. The email from the organization states that “PCI-SIG members are responsible for the design, manufacture and testing of their products to the 12VHPWR specification”.
“PCI-SIG wants to persuade all consortium members that manufacture and market PCI-SIG technologies (including 12VHPWR) to take all appropriate and reasonable steps to ensure end-user safety, including reviewing reported consumer-related issues. Participants are reminded that the PCI-SIG specification provides the technical information necessary for interoperability and does not address design requirements, manufacturing methods, materials, safety testing, safety tolerances, or workmanship. When implementing the PCI-SIG specification, participants are responsible for the design, manufacturing, and testing, including security testing, of their products.the letter says.
According to VideoCardz, with this letter PCI-SIG wants to defend itself against any possible claims regarding the design of cables with 12VHPWR connector.

Previously at NVIDIA reportedwho know about 50 cases of 12VHPWR connector meltdowns. The company has concluded that a common cause of the problem is that “the connector has not been fully inserted into the video card“. The company called warranty cases, but advised users to carefully make sure that the power connector on the video card is inserted all the way in.
