PCI-SIG makes safety plea over melting RTX 4090 cable issues • The Register

Nvidia and other GPU manufacturers have been asked by the consortium that created the specification for the 12VHPWR connector used in Nvidia’s GeForce RTX 4090 to “ensure end-user safety,” which has been the subject of multiple complaints about melting cables .

The PCI-SIG consortium said it made the latest statement to member companies in part in response to a lawsuit filed against Nvidia last month by a user whose RTX 4090 connector melted shortly after plugging the graphics card into their computer. The lawsuit alleges the meltdown poses a “serious electrical and fire hazard” and seeks damages from Nvidia for alleged fraud, among other things.

PCI-SIG said its message was also in response to a report “from a manufacturer” about possible problems with the 12VHPWR connector.

“PCI-SIG wishes to alert all members who manufacture, market or sell PCI-SIG technologies (including 12VHPWR interconnects) of the need to take all reasonable and prudent measures to ensure end-user security, including testing for the reported problem cases involving consumers alleged in the above lawsuit,” the organization said.

The statement added that the PCI-SIG is responsible for providing “necessary technical information for interoperability” in relation to its specifications, leaving crucial steps of their implementation to member companies.

“In implementing a PCI-SIG specification, members are responsible for the design, manufacture and testing, including security testing, of their products,” argued PCI-SIG. Unusually, PCI-SIG forwarded the message to The registry spontaneous.

The consortium’s statement comes after Nvidia said in mid-November that it believes RTX 4090 cables are melting because users don’t fully plug them in. The GPU manufacturer suggests that users insert the connector into the graphics card before inserting it into the motherboard to avoid such problems.

At the time, the GeForce designer admitted he was aware of 50 cases of RTX 4090 cables melting around the world, adding that he was “investigating additional ways to ensure the connector is secure.” The company is committed to expediting authorized returns of RTX 4090 cards from Nvidia and partners, regardless of the cable used.

Nvidia spoke out after mounting multiple complaints, including the lawsuit about RTX 4090 cables melting or burning following the launch of its $1,599 graphics card in October.

Due to the card’s extravagant power requirements – 450 watts for normal power consumption and 600 watts for overclocking – Nvidia introduced the 12VHPWR power connector to get enough juice. ®
