RTX 5090 Power Connector Hits 91.7°C Under DLSS 5 Load
QuasarZone's testing of the RTX 5090 Founders Edition recorded a 91.7°C temperature at the 12V-2x6 connector's sense-pin side while DLSS 5 was active. Power draw reached 647W during the test. The measurement highlights thermal stress on the power interface under heavy load.
QuasarZone's stress test of the RTX 5090 Founders Edition pushed the card through a demanding DLSS 5 workload, during which the 12V-2x6 connector's sense-pin region climbed to 91.7°C. This reading accompanied a substantial 647W power draw, indicating the GPU was operating near its electrical ceiling while the power interface absorbed significant heat.
The sense-pin side of the connector serves as a critical monitoring point for power-delivery status, so elevated temperatures there point to thermal buildup at a junction that must remain reliable under sustained load. The finding underscores the engineering challenge of feeding a near-650W component through a compact connector, and it may prompt closer scrutiny of airflow and cable management in high-end builds.
This reading could influence how enthusiasts and system integrators approach high-end GPU installations, potentially driving demand for better case ventilation or aftermarket connector solutions. If such heat becomes common in real-world use, it may affect long-term connector reliability or trigger thermal safeguards, shaping purchasing decisions for top-tier cards. Manufacturers could respond with revised designs or guidance, while mainstream users are unlikely to feel direct effects unless they adopt flagship hardware.
