A Chinese repair technician has addressed overheating issues affecting Nvidia RTX 50 series graphics cards by replacing standard 16-pin power connectors with versions featuring thicker pins. The specialist documented her work on an ASUS ROG Astral RTX 5090 that had suffered connector damage, noting that enhanced pin diameter reduces electrical resistance through increased surface area and improves mechanical stability.
Temperature monitoring revealed the modified connector maintained approximately 45 degrees Celsius under full 600-watt load conditions, contrasting sharply with standard connectors that have reached temperatures exceeding 100 degrees Celsius in some instances. The technician attributes widespread melting problems to inadequate contact between pins, which forces remaining connections to carry excessive current loads averaging 9.2 amperes per pin. While she cautions against using adapters despite improved thermal performance, the modification appears to substantially reduce failure risks associated with the current connector design across higher-tier graphics processing units.
