Nvidia thinks RTX 4090 cables melted because they weren’t fully plugged in

Weeks after Nvidia introduced that it was investigating experiences that the facility cables for its RTX 4090 graphics card had been melting and burning, the corporate says it could know why: they only weren’t plugged in all the way in which. In a submit to its buyer help discussion board on Friday, Nvidia says that it’s nonetheless investigating the experiences, however that its findings “counsel” an insecure connector has been a typical concern. It additionally says that it’s gotten round 50 experiences of the difficulty. Nvidia’s flagship card makes use of what’s referred to as a 12VHPWR energy connector, a brand new normal that isn’t natively supported by a lot of the energy provides that folks 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. Customers’ preliminary experiences blamed the adapter, with some saying that the melting cable had broken their $1,599 GPU as nicely.It may very well be straightforward to learn the corporate’s findings as shoving blame onto the customers. Positive, Nvidia doesn’t come proper out and say that it’s consumer error, but it surely’s closely implied within the submit. It additionally looks as if a really handy clarification, since individuals have been speculating for nearly a month that the difficulty is attributable to one thing extra advanced, like dangerous soldering or wires too small to reliably deal with the huge quantities of energy pumped by.Screenshot of a video showing a connector with clear lines on its plastic posts.That’s a big quantity of connector that may be out of the socket. Picture: GamersNexusHowever, GamersNexus, an outlet that’s revered within the PC-building group for its rigorous testing, principally got here to the identical conclusion earlier this week. A video posted on Wednesday by the outlet, which inspected broken adapters despatched in by viewers and achieved intensive testing and reporting on the difficulty, confirmed that the connectors had put on strains, implying that they hadn’t been fully inserted into the slot. GamersNexus even says that some individuals appear to have missed a full connection by a number of millimeters. Its video reveals that a free connection might trigger the plug to warmth up dramatically, if it had been plugged in poorly and tilted at an angle.Nvidia’s submit features a image of what the connector seems like when it’s not totally plugged in, and it appears a lot simpler to overlook than one thing that’s out by a full 2mm and being held at an angle (doubtlessly due to the cables being pulled again too tightly throughout set up). It’d be even simpler to overlook with a third-party RTX 4090 card as an alternative of the Nvidia model proven within the pictures under.In case you’ve acquired considered one of these playing cards in your laptop, it’s best to most likely double-check yours seems like the underside one.

One other factor that jumps out in regards to the image it posted is that the connector has a locking key. In concept, that’s a characteristic that may forestall this form of factor from occurring, so long as it provides good suggestions while you plug it in. In accordance with GamersNexus, nevertheless, the adapters don’t actually audibly click on into place, even when totally inserted.That apart, the testing achieved by Nvidia and GamersNexus doesn’t appear to level to manufacturing defects as the principle perpetrator (the outlet’s video on Wednesday did say that particles left throughout manufacturing might have been an aggrevating issue). Both approach, although, an unnamed spokesperson for the corporate instructed GamersNexus on Friday that “any points with the burned cable or GPU, no matter cable or GPU, it is going to be processed” for a substitute.
