Nvidia says it’s investigating two reports of RTX 4090 cards that have had power cables burn or melt.Reddit user reggie_gakil was the first to post details about their Gigabyte RTX 4090 issues yesterday, showing burn damage on the new 12VHPWR adapter cable that Nvidia ships with the RTX 4090.“We are in contact with the first owner and will be reaching out to the other for additional information.”Nvidia initially moved to this new 16-pin power connector for its own RTX 3090 Ti cards, and it has now become a standard on the RTX 40-series GPUs across vendors.The melting looks very similar to what has occurred with both of the Reddit posters’ RTX 4090 cards this week.New ATX 3.0 power supplies will help too, but there aren’t many on the market and not many PC gamers will want to spend extra to replace a working PSU just to get a native implementation of the 12VHPWR connector."
