Users of Nvidia GeForce RTX 50-series graphics cards continue to report issues with power connectors. A recent incident involved a GeForce RTX 5070, which has a power consumption of 250 W, experiencing a melted power connector.
The owner, posting under the username Gatlyng on Reddit, suggests that the issue might have been caused by improper installation. The user noted that an acquaintance installed the card and may not have fully inserted the power cable. A loose connection can increase electrical resistance, leading to localized overheating that damages contacts and melts the plastic connector.
This case is notable because the RTX 5070 has a significantly lower power draw compared to the RTX 5090, which is rated at 575 W. Despite this, the incident highlights ongoing concerns regarding the 12V-2x6 power connector standard.
Similar problems have been documented before. In April 2025, a Zotac RTX 5070 paired with a Seasonic Focus GX-750 power supply suffered from a melting power cable. Photos from that event showed a contact that appeared to have shifted inside the connector, though the exact cause remained undetermined.
