ATX 3.0 PSU user reports melted 12VHPWR cable

Back when the RTX 4090 first began making its way into the hands of consumers some found their 12VHPWR connectors melting on the side connected to the graphics card. Now, the first user report of a 12VHPWR cable melting on the PSU side has surfaced. 

In photos shared to Reddit, one be quiet! Dark Power 13 user found their native 12VHPWR cable had melted on the side connected to the power supply, reigniting some concerns around the reliability of 12VHPWR cables. The images show damage to the bottom row of pins on both the connector and the PSU port.

be quiet! is already investigating this issue and it is worth noting that right now, this is an isolated issue, with only one public report. If you encounter something similar, you should contact be quiet! support to report the issue. They may want to ask a few questions about your PC setup in order to try and find the root cause.

For now, we don't know exactly what caused the issue. When 12VHPWR connectors were melting on RTX 4090s, some degree of user error was found, but that user error was compounded by certain design decisions, as users were inadvertently not pushing in the connector all the way, or were accidentally loosening it while routing cables.

KitGuru says: It will be interesting to see exactly what went wrong here. Hopefully the cause of the issue can be recognised soon enough, although in rare cases like this, troubleshooting can take a bit longer.
