GIGABYTE RTX 5090 Suffers 16-Pin Connector Melting

A Mobil01 user reported a melted 16-pin (12V-2x6) power connector on a GIGABYTE RTX 5090 AORUS Master ICE despite limiting GPU power to 500W. Photos show the top row of pins burned, suggesting uneven contact or adapter-related loading; similar failures have appeared across RTX 50-series and some Radeon cards. Report advises ATX 3.1 PSUs, using native PSU cables, avoiding adapters, and monitoring connections.
