- Nvidia has said that it is not “expected” that cable fusion problems with RTX 5090 are produced
- The company reminded us of the changes made in the 16 -pin food connector after the RTX 4090 had problems
- However, a California -based repair workshop has indicated separately that it still repairs RTX 4090 melts “daily.”
Nvidia has assured us that “it is not expected” that the RTX 5090 GPU has problems with the food connectors that melt, as seen with the RTX 4090 (and we will return to deepen the history and the current situation with the flagship of Lovelace). later in this article).
The Quasarzone South Korean technology site published an article detail Pins used by RTX 4090, and also used in the imminent RTX 5090.
An event assistant noticed that there was a problem with the connector that melted due to overheating with RTX 4090 and asked: “Has this been resolved with the RTX 5090?”
A representative of NVIDIA replied: “It is expected that such problems do not occur with the RTX 50 series. In response to the problem of that moment, some changes in the connectors were made and, after approximately two years, we believe that these problems were solved” .
I must point out that this is translated from the Korean and we must firmly take it into account in terms of the accuracy of what has been said here and the exact meaning, but the essence is quite clear.
ANALYSIS: PARANOIA OF POWER
Well, it’s time to press the rewind button for a moment. You may remember the subject of the melted cable with the badge of Lovelace when it first came out, but it is worth making a quick summary. (Or if you want to know the complete background, go first here).
In a nutshell, this was a problem with the 16 -pin connector (12VHPWR) of the PC power supply to the RTX 4090 graphics card that was not correctly placed on the card and, as a result, overheated. If that overheating reached a sufficiently critical level, the plastic would begin to melt (and a poor connection was more likely if the adapter had to bend at a more acute angle of the ideal, due to space problems within the PC housing ).
After the appearance of these reports on melted adapters, NVIDIA introduced a new 16-pin feed connector design (12V-21×6, a 12VHPWR review) to mitigate the possible fire risk of a poorly placed connector.
Basically, Nvidia attributed the problem to a user error (he did not make sure the connector was completely plugged in) and then changed the connector to minimize any possibility that this happened. This connector review involved making changes in the length of the plugs, including shortening the “detection” plugs, so that if the connector is not complete instead of continuing to function and cause the problem of overheating).
This will be the same situation for the RTX 5090, so the security aspect should be fine, or that is the statement that Nvidia is doing here. Except that there is a remarkable nuance in the (translated) language expressed in terms that “it is not expected” that merger problems occur with the RTX 5090.
This does not mean that there is no problem, but of course we must be careful with the translation of the Korean, as already noted. The additional concern with the RTX 5070 is that it seriously increases the use of energy to 575 W (at least, compared to the 450 w of the RTX 4090), but despite that, Nvidia says that it does not expect to see any problem with the connectors They melt.
Look
The other concern here, as Videcardz points out, is that although the Nvidia representative observes that after two years the problems of the melted cable with the RTX 4090 seem to have been resolved, there were still reports that this happened throughout 2024, and Even as recently as this month, January 2025. That is according to Northridgefix (a technology repair workshop in California, USA), which claims to receive RTX 4090 plates with melted connectors daily. Base still.
Then, there is a paranoia level here, and that is not unexpected in itself, particularly considering, as noted, how much more the RTX 5090 progresses with its energy consumption compared to its predecessor.
Ultimately, the test will be in the power cable pudding (there is a dessert that sounds unattractive) and how people take with the new flagship GPU when it is launched. Until then, obviously we cannot judge the RTX 5090 for the fusion score, but it is expected that in one way or another, this is a problem against which Nvidia would have been an absolute priority to design and completely solve. bed.
