- Nvidia said it was not “expected” that cable fusion problems occur with the RTX 5090
- The company reminded us of the modifications to the 16 -pin power connector after the RTX 4090 has encountered problems.
- However, a California -based repair workshop reported separately that it still repaired the RTX 4090s melted on a “daily” basis.
Nvidia assured us that the RTX 5090 GPU should “not” have fusion problems of the supply connectors, as we have seen with the RTX 4090 (and we will come back to dive into the history and the current situation of the current situation of LOVElace flagship product, further in this article).
The South Korean technological site Quasarzone published an article detailing the day “RTX AI” of Nvidia which includes a session of questions and answers (noticed by Videocardz), and one of the questions asked brought to the supply connectors at 16 Pins used by RTX 4090, and also used in the imminent RTX 5090.
A participant in the event noted that there was a problem of fusion of the connector due to an overheating with the RTX 4090 and asked: “Has it been resolved with the RTX 5090?
A representative of Nvidia replied: “We expect such problems not happening with the RTX 50 series. In response to the problem of the time, certain modifications were made to the connectors and, after about two years , we think these problems have been solved.
I must note that this is translated from the Korean, and we should keep this firmly in mind in terms of accuracy of what has been said here and exact, but the essential is quite clear.
Analysis: paranoia of power
Okay, it’s time to press the rewind button for a moment. You may remember the case of melted cables with the Lovelace flagship GPU when it was first out, but it is worth engaging in a brief summary. (Or if you want the full context, go first here).
In a word, it was a problem due to the fact that the 16 -pin connector (12VHPWR) of the PC power supply to the RTX 4090 graphics card was not properly inserted into the card, which led to a overheated. If this overheating reached a sufficiently critical level, the plastic would start to melt (and a poor connection was more likely if the adapter had to be folded at a more pronounced angle than Ideal, due to space problems inside the PC case).
Following the emergence of these founding adapter reports, NVIDIA introduced a new 16-pin power connector design (12V-2X6, a 12VHPWR revision) to mitigate the possible risk of fire of a bad connector inserted.
Essentially, Nvidia assigned the problem to a user error (not making sure that the connector was completely connected), then decided to change the connector to minimize any risk that this happens. This revision of the connector involved modifying the length of the pins, in particular by shortening the “meaning” pins, so that if the connector is not completely in place, or if it is loosening and begins to fall, the graphics card s ‘will turn off and will not turn off. Operating (rather than continuing to work and cause an overheating problem).
It will be the same situation for the RTX 5090, so the security aspect should be good, or it is Nvidia’s assertion here. Except that there is a notable nuance in the language (translated) here which has been formulated in terms of “we do not expect” that fusion problems occur with the RTX 5090.
This is not a final solution to any problem, but of course, we must be wary of the translation of Korean, as we have already noted. The additional concern with the RTX 5070 is that it considerably increases energy consumption to 575 W (at least, against 450 W with the RTX 4090), but despite this, Nvidia says that it does not expect to see Problems with the melting of connectors.
Look over
The other concern here, as Videocardz points out, is that even if the representative of Nvidia observes that after two years, the problems of casting cables with the RTX 4090 seem to have been resolved, there have still been reported reports From that throughout 2024-and even as recently as this month, January 2025. It is according to Northridgefix (a technical repair workshop in California, the United States), which claims to receive RTX 4090 cards daily with Mettled connectors. always.
There is therefore a level of paranoia here, and it is not surprising in itself, all the more, as indicated, that the RTX 5090 pushes its energy consumption further compared to its predecessor.
In the end, the proof will be in the pudding of the power cable (there is an unattractive dessert) and in the way people get along with the new flagship GPU when it was released. By then, we cannot obviously judge the RTX 5090 on its merger score, but we could hope that in one way or another, it is a problem against which Nvidia would have been a priority absolute to conceive and resolve fully. bed.
