Nvidia lastly broke its silence and suggests improperly seated 12VHPWR connectors are mostly to blame for those GeForce RTX 4090 power cable meltdowns.
The business, which as a result considerably has been mum other than to validate it was investigating the challenge, issued a statement to Avid gamers Nexus that also confirmed how a lot of cases it appreciates of.
“We are actively investigating the stories. We are informed of about 50 scenarios globally,” a business spokesperson explained to Avid gamers Nexus editor-in-chief Stephen Burke, according to a online video Avid gamers Nexus posted to its YouTube channel Friday early morning.
“Our findings to day advise that a typical issue is that connectors are not fully plugged into the graphics card,” Nvidia told Burke. “To support ensure the connector is safe, we endorse plugging the electrical power dongle into the graphics card 1st to ensure it’s firmly and evenly plugged in, in advance of plugging the graphics card into the motherboard.”
Nvidia officers also advised Burke that returned cable adapters all appeared to exhibit dress in harm indicating they weren’t fully seated. The firm also posted its assertion on its purchaser assistance page exactly where it demonstrates what a effectively inserted cable seems to be like.
Nvidia’s assertion largely appears to again up what Burke and his staff found yesterday: An excessively loose 12VHPWR connector in the GPU can lead to high temperatures which melts the connector.
In the Avid gamers Nexus investigation, the unsuccessful connectors Burke obtained generally experienced bodily hurt, indicating the plug experienced mostly backed out of the GPU. Avid gamers Nexus also mostly concluded that particles from manufacturing, as effectively as particles caused by customers possibly inserting and getting rid of the connector, could probably lead to the RTX 4090 cables to soften but the most very likely lead to was a unfastened connector.

Other people, which include Techlab.net.br’s Ronaldo Buassali and Jon Gerow, Director of Study at Corsair, had performed their possess screening formerly and concluded the connector is properly in a position to take care of the current remaining pushed by it—so extended as it is totally linked.
Of class, the lingering issue is no matter if the improper insertions stem from an fundamental connector style problem or not. With evidence now very clear that the cable is capable supporting the electric power at the rear of it, quite a few are pondering if the latch could be enhanced or not.
Nvidia officials did inform Burke that “We are investigating additional methods to assure that the connector is secure before powering on the graphics card.”
Other concepts have been floated, this kind of as owning the playing cards refuse to write-up if the sense pins on the plugs are not entirely seated. The PCI-SIG team, in truth, has been explained to be thinking about style improvements to the new plug.
Nvidia also responded to fears by individuals that it would not honor warranties if a customer takes advantage of a “third-party adapter” 12VHPWR connector, this kind of as the customized and modded ideal-angle cables individuals are obtaining in hopes of keeping away from a melted connector. That elevated considerations Nvidia and board associates would then not honor a guarantee if the indigenous 12VHPWR connector on a new PSU was applied.
In a assertion produced to PCWorld a organization spokesman reported the issue was unwarranted. “NVIDIA and our companions are fully commited to supporting our customers, no matter of the cable or electric power provide utilised,” an Nvidia spokesman explained.
Potentially far more importantly, Nvidia also informed Avid gamers Nexus that it and associates would honor RMAs from playing cards destroyed by incorrect insertion. “Anybody who has an concern [relating to this] will be taken treatment of,” the business instructed Burke. “We’ll expedite an RMA.”
So how quite a few GeForce RTX 4090 playing cards endured from melting connectors? Avid gamers Nexus reports that board associates have told it 125,000 GeForce RTX 4090 playing cards have been sold, which would place the known failure amount at .04 percent, Burke stated.
The statement will come a working day soon after a GeForce RTX 4090 operator apparently filed a course-action accommodate in opposition to Nvidia around the melting connectors, in accordance to a report in Tom’s Hardware.
Lucas Genova submitted his accommodate on Nov. 11 and alleges that Nvidia “marketed and marketed the RTX 4090 with a faulty and unsafe ability cable plug and socket, which has rendered consumers’ playing cards inoperable and poses a critical electrical and hearth hazard for each individual and every purchaser.”
