An NVIDIA RTX 4090 owner experienced the 16-pin 12VHPWR power connector melting, resulting in damage to both the graphics card and power supply despite power being limited to 75%.
RTX 4090 power problems
Dangerous 12VHPWR connector
Troubles with the 16-pin 12VHPWR power connector for NVIDIA RTX 4090 video cards continue. The owner of the graphics accelerator shared a story on the Korean forum Quasar Zone about how a melted connector damaged not only the MSI GeForce RTX 4090 Suprim X 24G video card, but also the FSP Hydro power supply.
Usually the 12VHPWR would melt on either the graphics card or the power supply, but in this case both devices were affected. Surprisingly, the RTX 4090 wasn't even running at full power - the user limited it to 75%.
Safety First
Some RTX 4090 owners are experimenting with power limiting to improve efficiency or reduce the risk of melting the 16-pin connector. However, as you can see, this is not a panacea. Despite the introduction of a new version of the 12V-2x6 connector by PCI-SIG, many RTX 4090 from the first batches are still working for users and sometimes fail even two years after release. Even third-party connection cables, such as those from the popular manufacturer Cablemod, do not help - the company was forced to recall its products due to the danger.

I saw this story on the forum. It's terrible that the melted 12VHPWR connector ruined not only the video card, but also the power supply. 🤯 Looks like the problem is still relevant, even with the new PCI-SIG standard.
Сара
Yes, this is a big problem for RTX 4090 owners. I would be wary of using this video card until NVIDIA finally solves the problem. 😬 It’s a shame that such expensive components were damaged.
Марко
I've heard that even limiting the power doesn't always help. This guy limited it to 75% but melting still happened. 😓 Maybe we should wait until updated versions of video cards and power supplies come out?
Франсуа
Yes, apparently, even third-party cables do not completely solve the problem. Cablemod had to recall its products due to the risk of fire. 🔥 This is already too serious to ignore.
Игорь
Hmm, I think all these problems are overblown. 🙄 How many people have successfully used the RTX 4090 without any incidents? You just need to be careful not to overheat the video card.
Анна
Igor, you are wrong. 😕 Even if most users do not encounter problems, this does not mean that they should be ignored. The risk is too great, because we are talking about expensive equipment.
Маркус
I agree with Anna. Safety must come first. 🧐 Maybe we should wait until NVIDIA releases an updated version of video cards with an improved power connector?
София
Or maybe it's better to switch to AMD altogether? 😉 I heard that they don’t have such problems with power connectors on new cards.
