Nvidia is working to resolve issues with the RTX 4090’s 12+pin connectors and adapters, following complaints of these connectors burning and melting due to high power consumption, which generates excessive heat.
RTX 4090: Nvidia works to solve the problems with the 12+4 pin connector
According to Igor Wallossek, Nvidia and the AIB partners are working tirelessly to find a solution to the 16-pin connector issues with the GeForce RTX 4090 graphics card, which is the only model released so far from the RTX 40 series.
This issue was reported a few days ago, where the new 12+4 pin connectors were burning or melting with the RTX 4090.
According to the tests of Ronaldo Buassali, from TecLab, an incorrect connection of the 16-pin cable can cause large thermal variations and that may be what is happening with the adapters. Testing was done testing various loads, even up to 1530W. When users bend the adapter, it can cause thermal variations that lead to unusual temperatures. The adapters and the 12+4 pin connector would not be well designed. A bad connection can generate temperatures of 100 degrees or higher.
Nvidia is already dealing with this matter with its manufacturing partners, probably to design new connectors and adapters that do not generate such high temperatures.
Igor Wallossek’s tests also indicate that the materials used by Nvidia for the 12+4 pin connector are also poor and that some ATX 3.0 power supplies could have this same problem of poor quality connectors.
On the other hand, the problems of high temperatures and the damage of the connectors and adapters are generated in prolonged use of the computer, which is calculated between 10 and 30 hours of operation to reach temperatures that are a real risk. That is to say, this problem is not generated immediately but in prolonged use, so it is difficult to replicate the failure. We will keep you updated with all the news about this.
