Nvidia lastly broke its silence and says improperly seated 12VHPWR connectors are largely responsible for these GeForce RTX 4090 energy cable meltdowns.

The corporate, which to this point has been mum apart from to substantiate it was investigating the issue, issued a press release to Avid gamers Nexus that additionally confirmed what number of instances it is aware of of.

“We’re actively investigating the reviews. We’re conscious of about 50 instances globally,” an organization spokesperson informed Avid gamers Nexus editor-in-chief Stephen Burke, in response to a video Avid gamers Nexus posted to its YouTube channel Friday morning.

“Our findings so far counsel {that a} frequent situation is that connectors aren’t absolutely plugged into the graphics card,” Nvidia informed Burke. “To assist make sure the connector is safe, we suggest plugging the facility dongle into the graphics card first to make sure it’s firmly and evenly plugged in, earlier than plugging the graphics card into the motherboard.”

Nvidia officers additionally informed Burke that returned cable adapters all appeared to point out put on harm indicating they weren’t absolutely seated. The corporate additionally posted its assertion on its buyer assist web page the place it exhibits what a correctly inserted cable seems to be like.

Nvidia’s assertion largely appears to again up what Burke and his workforce found yesterday: An excessively unfastened 12VHPWR connector within the GPU can result in excessive temperatures which melts the connector.

Within the Avid gamers Nexus investigation, the failed connectors Burke obtained typically had bodily harm, indicating the plug had largely backed out of the GPU. Avid gamers Nexus additionally largely concluded that particles from manufacturing, in addition to particles brought on by shoppers presumably inserting and eradicating the connector, might presumably trigger the RTX 4090 cables to soften however the more than likely trigger was a unfastened connector.

Others, together with Techlab.internet.br’s Ronaldo Buassali and Jon Gerow, Director of Analysis at Corsair, had performed their very own testing beforehand and concluded the connector is nicely in a position to deal with the present being pushed by way of it—as long as it’s absolutely linked.

After all, the lingering query is these improper insertions steam from an underlying connector design situation. With proof now clear that the cable is succesful supporting the facility behind it, many are questioning if the latch could possibly be improved or not.

Nvidia officers did inform Burke that “We’re investigating extra methods to make sure that the connector is safe earlier than powering on the graphics card.”

Different concepts have been floated, resembling having the playing cards refuse to put up if the sense pins on the plugs aren’t absolutely seated. The PCI-SIG group, actually, has been stated to be contemplating design adjustments to the brand new plug.

Nvidia additionally responded to considerations by shoppers that it will not honor warranties if a shopper makes use of a “third-party adapter” 12VHPWR connector, such because the customized and modded right-angle cables individuals are shopping for in hopes of avoiding a melted connector. That raised considerations Nvidia and board companions would then not honor a guaranty if the native 12VHPWR connector on a brand new PSU was used.

In a press release launched to each PCWorld an organization spokesman stated the priority was unwarranted. “NVIDIA and our companions are dedicated to supporting our prospects, whatever the cable or energy provide used,” an Nvidia spokesman stated.

Maybe extra importantly, Nvidia additionally informed Avid gamers Nexus that it and companions would honor RMAs from playing cards broken by improper insertion. “Anyone who has a difficulty [relating to this] will likely be taken care of,” the corporate informed Burke. “We’ll expedite an RMA.”

The assertion comes a day after a GeForce RTX 4090 proprietor apparently filed a class-action go well with in opposition to Nvidia over the melting connectors, in response to a report in Tom’s {Hardware}. 

Lucas Genova filed his go well with on Nov. 11 and alleges that Nvidia “marketed and bought the RTX 4090 with a faulty and harmful energy cable plug and socket, which has rendered shoppers’ playing cards inoperable and poses a critical electrical and fireplace hazard for every purchaser.”
