Nvidia thinks the RTX 4090 cables melted as a result of they weren’t absolutely plugged in.

Weeks after Nvidia introduced it was investigating stories that its RTX 4090 graphics card’s energy cables have been melting and catching fireplace, the corporate says it might know why: they weren’t plugged in all the best way.

In a submit on its buyer assist discussion board on Friday, Nvidia says that it’s nonetheless investigating the stories, however that its findings “counsel” an insecure connector has grow to be a typical concern. It additionally says that it has obtained practically 50 stories of the difficulty.

Nvidia’s essential card makes use of what is called a 12VHPWR energy connector, a brand new normal that isn’t natively supported by lots of the energy provides that individuals have already got of their PCs. Due to that, it ships an adapter — or “energy dongle,” as Friday’s submit calls it — within the field. Early consumer stories blamed the adapter, with others saying a melting cable broken their $1,599 GPU as nicely.

It may be simple to learn the corporate’s findings as pushing the blame onto customers. Certainly, Nvidia doesn’t exit with say that it is consumer error, nevertheless it’s closely implied within the submit. It additionally looks as if a quite simple rationalization, since individuals have been speculating for nearly a month that the difficulty is attributable to one thing extra advanced, similar to a foul fuse or wires too small to reliably deal with the massive quantity of energy being transmitted.

Nonetheless, Nexus gamers, a facility that’s revered within the PC constructing neighborhood for its rigorous testing, primarily got here to the identical conclusion earlier this week. A video posted Wednesday by the station, which examined broken adapters despatched in by viewers and performed in depth testing and reporting on the difficulty, confirmed that the connectors had put on strains, that means they weren’t absolutely seated. Nexus gamers it even says that some individuals appear to have missed the right connection by a number of millimeters. His video exhibits {that a} free connection may cause the plug to overheat, if plugged in incorrectly and bent at an angle.

Nvidia’s submit features a image of what the connector appears to be like like when it isn’t absolutely plugged in, and it appears to be like quite a bit simpler to overlook than one thing that is a full 2mm out and held at an angle (in all probability because of the cables being pulled again too laborious throughout set up). It could be simpler to get away with a third-party RTX 4090 card as a substitute of the Nvidia model pictured under.

If in case you have certainly one of these playing cards in your pc, it’s best to in all probability double test that yours seems to be low.

It is value noting although, that Nvidia could be completely with out blame right here. One other factor that jumps out over the posted picture is that the connector has a lock key. In idea, that is a characteristic that might stop this form of factor from occurring, so long as it offers good suggestions whenever you plug it in. In accordance with Nexus gamersnevertheless, the adapters don’t click on audibly into place, even when absolutely inserted.

That apart, assessments performed by Nvidia and GamersNexus do not appear to level to manufacturing defects as the primary perpetrator (the channel’s video on Wednesday stated that particles left throughout manufacturing may very well be an aggravating issue). Both manner, an unnamed firm spokesperson stated Nexus gamers on Friday that “any burnt cable or GPU points, no matter cable or GPU, will probably be processed” for substitute.
