You can now melt your power cable and destroy your video card cheaper than ever before.

Latest victim was an RTX 5070.

This problem is predictable with the RTX 5090, which draws 575W over a connector rated for a maximum of 600W. 5% out of tolerance and your card is fried.

It shouldn't happen on the 250W 5070 though.
