Increasing RTX 4090 problems: Nvidia graphics 16-pin connector melts

You may have already read reports about the risk of melting the 16-pin connector of the Nvidia GeForce RTX 4090 graphics card. However, the matter does not end there; Because one of the owners of this graphic has made a report about the failure of the 12VHPWR connector connected to the new ATX 3.0 adapter.

GeForce RTX 4090 graphics has a very high price and is considered one of the best gaming graphics cards in the market. However, the high price does not seem to be the reason for the fear of users; Because the 16-pin graphic power connector is a fire hazard. So far, there are 18 confirmed reports that custom RTX 4090 models are also experiencing the issue. Nvidia quickly addressed the issue and told its business partners to return the melted RTX 4090 cards to the company’s labs for further analysis.

One of the users who used MSI GeForce RTX 4090 Gaming X Trio 24G and MEG Ai1300P power supply, after reading other users’ feedback about RTX 4090’s 16-pin power connector melting, chose ATX 3.0 power supply with 12VHPWR power connector. Unfortunately, the published images show that the 16-pin connector of his graphics card is also melted. He didn’t share any photos of his system, but says he didn’t over-bend the cable, as bending the cable is said to cause fire problems. Anyway, MSI has contacted this user to replace the graphics and power.

to report Tom’s HardwareNvidia has not shared the results of its investigation into the melting of the RTX 4090’s 16-pin power connector; This shows that the company is probably still investigating the root of the problem. The published reports were only related to the 16-pin connector, but a report from another user raises the question of whether the issue goes deeper than the design of Nvidia’s 16-pin power adapter. It is possible that the problem is related to the 12VHPWR connector, the quality of the components, the RTX 4090, or a combination of various factors. When the 12VGPWR power connector was introduced on Nvidia’s RTX 40 series graphics cards, there were concerns about the risk of transferring 600W through this method. GeForce RTX 4090 is a 450 watt graphics card; But its power consumption quickly increases from 500 to 550 watts when overclocking, running benchmarks or tests like FurMark.

It seems that a different connector or a direct connection to the power can solve the problem of melting the 16-pin connector of Nvidia to some extent; But apparently, using the mentioned solution is not easy. Currently, ATX 3.0 power supplies are very rare in the market, and probably because of this, we haven’t seen many reports of the 12VHPWR power connector melting. It is possible that the melting of the connector happened completely by accident; But now 18 similar incidents have been registered in this case.

GeForce RTX 4090 owners are probably in a more difficult situation right now, as the power adapter and connector of this graphics card seem insecure. So should we stick with integrated graphics while we wait for a fix? Unfortunately, since the beginning of this disaster, Nvidia has been silent that this situation does not help to fix the problem.
