GoKawiilDigital Storm RTX 5090 prebuilt's power connector melts after a year in storage, owner says
A Tom's Hardware reader, Anthony DeMarco, says the 12V-2x6 power connector on his $5,245 Digital Storm Corsa prebuilt melted weeks after he began using it, despite the PC having sat boxed and unused for roughly a year after purchase. The system, built around an Nvidia RTX 5090 and a 1,000-watt Digital Storm power supply, reportedly suffered the worst damage at the PSU itself, with cables fused into the connector.
GoKawiil's interpretation of the reporting above, not reported fact.
The case highlights ongoing concerns about the reliability of Nvidia's 12VHPWR/12V-2x6 connector standard, which has been linked to melting incidents since its introduction. Because the PC was assembled and sold by a system builder rather than built by the user, responsibility for warranty claims could fall into a dispute between the PC builder, the GPU maker, and the power supply manufacturer, potentially leaving the customer without clear recourse. This suggests prebuilt buyers may face added complications when such failures occur, compared with DIY builders who deal directly with a single component's warranty.
- A Digital Storm Corsa prebuilt with an RTX 5090 reportedly had its power connector melt after about a year of mostly unused storage.
- The damage reportedly extended beyond the GPU to the system's 1,000-watt power supply, called the 'most severe' point of failure.
- The incident raises questions about liability when a prebuilt PC's components fail, since multiple companies could be involved in a warranty dispute.
CableMod 12V-2x6 Angled Adapter — Given the recurring melting issues with 12VHPWR/12V-2x6 connectors on high-wattage RTX 5090 cards, a quality angled adapter can reduce cable strain and improve connection seating, which are common culprits in these failures. It's a cheap bit of insurance for anyone running a power-hungry GPU like the one in this story.
