First RTX 5070 with melted power connector reported

In recent months, we've seen several RTX 5090 and RTX 5080 buyers reporting issues with the power connector melting. Now, we have our first instance of this phenomenon happening to an RTX 5070. 

According to @ere9w (via VideoCardz), the system reportedly included a Zotac RTX 5070 and a Seasonic Focus GX-750 power supply. The photos shared by the user suggest that the cable itself sustained the damage, rather than the graphics card or the power connector/socket.

This incident echoes the findings of in-depth investigations by Der8auer, who revealed a power imbalance between the connections of 12V-2×6 and 12VHPWR cables used with the Nvidia RTX-50 series. Der8auer's analysis of the six live cables on these connectors, when paired with an RTX 5090, demonstrated that power wasn't evenly distributed. Instead, a single wire was observed carrying a disproportionately large load, leading to excessive heat generation.

While the RTX 5070 is a lower-power GPU (250W TDP) than the RTX 5090 (575W TDP), the same principle applies. If a significant portion of the 5070's power draw is channelled through a single wire, overheating is possible.
