NVIDIA RTX 5090 Connector Melting Sparks Safety Concerns

Owners of the NVIDIA GeForce RTX 5090 are facing a serious hardware reliability issue that threatens the safety of their systems. The 12V-2×6 power connector on the flagship GPU has been reported to melt and burn under normal operating conditions. This defect forces buyers to question the safety of the new power standard and the durability of their expensive components. Users must monitor their hardware closely to prevent potential fire hazards or permanent damage to their graphics cards.

Reports of melted 12V-2×6 connectors raise hardware safety questions

The primary device at the center of these reports is the NVIDIA GeForce RTX 5090 Founders Edition. Tech publication Club386 detailed an incident where their review unit suffered a catastrophic failure of the power interface. The damage was severe enough to char both the connector on the graphics card and the cable plugged into it. This specific model uses the new 12V-2×6 standard, which replaces the older 12VHPWR connector used in previous generations.

• Power Connector Type: 12V-2×6 (16-pin)
• Power Supply Used: Be Quiet Dark Power 13 (1000W)
• Power Cable Configuration: Single 12V-2×6 cable

Club386 identified the root of the problem as a flawed design in the 16-pin connector mechanism itself. Their unit failed while running on a single 12V-2×6 cable connected to a 1000W Be Quiet Dark Power 13 power supply. The evidence shows that the connector became a hot, smouldering mess despite the use of high-quality components. The publication states there appears to be no user error, pointing directly to the connector engineering as the cause.

This incident is not isolated to a single unit, indicating a broader issue with the RTX 50 series power delivery. YouTuber Daniel Owen also reported a melted connector on his RTX 5090, though he was using an adapter in that case. The recurrence of these failures suggests that the new power standard may be prone to thermal issues across different setups. The repeated reports have led to widespread concern about the long-term reliability of the RTX 5090.

The core issue remains the structural integrity of the 12V-2×6 connector on the GeForce RTX 5090. Multiple independent reports confirm that the connector can melt and burn, creating a significant safety risk. Club386 explicitly calls the design flawed and unfit for its intended purpose. Until NVIDIA addresses this defect, users of the RTX 5090 face a tangible risk of hardware failure.
