Yes, that is what has been reported. It appears that MSI is using higher gauge wire than what the 600w cable spec. calls for on their 12VHPWR cable. Their cable is likely fine for other 4000 series cards that are coming but not for the 4090 (with its ability to draw 450-600w, depending upon the model).
Sorry, there was a problem. Please try again later.Summary of update from GamersNexus’s recent video: -Failure rate is 50 out of about 125,000 or 0.04~0.05%. In every instance Nvidia has investigated, the issue appeared to be improper installation. -Nvidia recommends installing the cable to the GPU before installing it on the motherboard so you can be sure you get it fully seated. -Nvidia is still replacing cables / cards even when user is at fault. -Third party cables DO NOT VOID YOUR WARRANTY if you are choosing to use e.g. CableMod cables or adapters. There was some confusion about this from an article on TomsHardware. CableMod has been working directly with Nvidia on developing their solution(s). Long story short: PLUG YOUR CABLE IN ALL THE WAY and you shouldn't have any issues, barring incredibly rare manufacturing defects that would be just as likely on any other device.
Sorry, there was a problem. Please try again later.I am using it with my MSI 4090 video card without any problems. People should be inserting the 12 vhpwr cable entirely in—the loose connections cause melting problems.

Sorry, there was a problem. Please try again later.I haven’t had any thermal issues on the cable after a month of use so far. Made sure both ends fully seated and no crazy bends and that seems to minimize chances of failures.
Sorry, there was a problem. Please try again later.I have been using this PSU with my 4090 for 1 year now. We game pretty hard over here, some sessions lasting 10+ hours. This PSU has been flawless paired with my rtx4090.
Sorry, there was a problem. Please try again later.While this has been happening, it seems like most testing shows that it's the connectors more so than the cables. The connectors don't have the same "Click" that lets you know you plugged it in all the way. This leaves cables that don't fully connect and higher electrical resistance. If you plug the cable in nice and snug, then push a little harder for good measure you should be good. The connectors may be changed in the future to ensure that they don't have a chance for failure in the future.
