A few alarming rumors about the beefy RTX 4090 surfaced last month. The problem originated from the RTX 4090's 12VHPWR power adapter melting under certain conditions. About 20 additional incidents have now been gathered and posted in a Megathread on the Nvidia subreddit. Furthermore, ATX 3.0 power supply are the source of the most recent allegations of melting power connections.
Previously, the adaptor that made it possible for many 8-pin connections to work as a 16-pin was partially to fault. It was discovered that this adapter is very brittle and that it may cause the problems we've seen if bent too near to the connection. However, the adapter would not be required if the power supply were an ATX 3.0. The expectation was that we would have overcome all of these issues. But when using their RTX 4090 on Friday and later Saturday, two customers complained that the 12VHPWR connections had melted.
These power supplies are the 1,000W MPG and 1,300W MEG PSUs from MSI. Both power supplies are ATX 3.0 and come with the 16-pin RTX 4090 cable. However, when using the RTX 4090, they both had a melting connection. There are now only two accounts of this occurring. Therefore, it can only be the result of malfunctioning hardware rather than a general problem with the ATX 3.0 power supply. However, additional reports might come soon since it's still early in the process.

The RTX 4090 from Nvidia is hot.
Without a question, the RTX 4090 is a highly powerful graphics card. That kind of performance, however, obviously comes with a lot of heat. And the number of verified complaints of these problems is getting to the point where it is a little worrying. It is hoped that Nvidia can fix these problems or at the very least advise consumers on how to stay clear of them. All the same, owners of an RTX 4090 should be alert for any difficulties related to melting connections.
