NVIDIA GeForce RTX 5090 Melts 12V-2×6 Connector Despite -100 W Power Limit

What happened

A user report details a melted 12V-2x6 power connector on an NVIDIA GeForce RTX 5090 GPU despite applying a -100W power limit and undervolt. The incident adds to documented reliability concerns around the connector standard and unofficial adapters, which are linked to unstable connections causing localized overheating. Neutral: This is a technical reliability issue for a specific, unreleased high-end component; it does not indicate a broader supply chain disruption or immediate trading impact for mainstream electronic components.
