PCI Standards Group Deflects, Assigns Blame for Melting GPU Power Connectors

An anonymous reader shares a report: Nvidia's new RTX 4090 and 4080 GPUs both use a new connector called 12VHPWR to deliver power as a way to satisfy ever-more power-hungry graphics cards without needing to set aside the physical space required for three or four 8-pin power connectors. But that power connector and its specifications weren't created by Nvidia alone -- to ensure interoperability, the spec was developed jointly by the PCI Express Special Interest Group (PCI-SIG), a body that includes Nvidia, AMD, Intel, Arm, IBM, Qualcomm, and others. But the overheating and melting issues experienced by some RTX 4090 owners recently have apparently prompted the PCI-SIG to clarify exactly which parts of the spec it is and is not responsible for. In a statement reported by Tom's Hardware, the group sent its members a reminder that they, not the PCI-SIG, were responsible for safety testing products using connector specs like 12VHPWR. "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," the statement reads. "When implementing a PCI-SIG specification, Members are responsible for the design, manufacturing, and testing, including safety testing, of their products."
