A few weeks ago, some early adopters Nvidia’s New Flagship RTX 4090 GPU card power connector Heat and melt the plastic casewhich can damage your ridiculously fast and expensive GPU.
For Nvidia’s part, the company is still investigating the failure. An Nvidia representative said, “We are continuing to investigate the reports, but have no further details to share yet.” talk to kit guru Earlier this week. However, a YouTuber on the Gamers Nexus channel said, Conduct your own in-depth researchin short, they believe most of the problems are caused by improperly installed power connectors. We believe that seed damage is extremely rare.
A mistake Gamers Nexus was able to reproduce in the lab was plugging the 12VHPWR power connector into the RTX 4090 without fully inserting it, bending the cable to one side and making the connection even worse. After just a few minutes of testing, the high power resistance of the loose connection generated heat in excess of 250 degrees Celsius, producing smoke and visible bubbles as the connector melted in the socket.
Gamers Nexus describes the issue as “a combination of user error and design flaws.”i.e. cable that is It is melted because it is not fully inserted. But due to the lack of a tactile “click” sound and a more robust retention mechanism, this kind of error is more likely to occur with the he 12VHPWR connector than with the older 6-pin and 8-pin PCIe power connectors. The size of 4090 and 4080 cards also exacerbates the problem. The card may fit tightly even in relatively large ATX PC cases. You may have to bend the cable in some way to get the case back on. Such bending can loosen the connection and cause overheating and melting. In the Gamers Nexus test.
In particular, disability can affect Any Cables or adapters that use a 12VHPWR connector – This applies to both types of adapters that Nvidia and its partners have used in the past for the 4090, as well as “native” 12VHPWR cables that connect directly to power without an adapter. Previous analysis suggested that adapters from certain manufacturers may be more prone to failure than others, but Gamers Nexus didn’t find that to make a difference. , which probably means that the 12VHPWR adapter that ships with the RTX 4080 card might have the same problem.
The best thing for now is to make sure the power connector is plugged in firmly. If it’s plugged in, you should be able to pull it pretty hard without actually pulling it out (we were able to test this first hand). Also, be careful not to bend the power cable too hard in any direction. We’ll keep an eye out for official statements from Nvidia to see if they have any further recommendations or plans for some sort of recall or replacement of the affected cards.
