RTX 5090 Connector Melting Persists Despite Mitigations
8.3
Reports of 16-pin connector melting on NVIDIA's flagship RTX 5090, launched at CES 2025, began within ten days of retail availability and have continued weekly into a year after launch. Independent tests show the ATX 3.1 12V-2x6 connector can reach about 150°C under full load, while vendors like MSI and ASRock have introduced yellow-tip connectors, PSU safeguards, and sensor-equipped cables to mitigate failures.
Key Points
- 1Documented repeat incidents show 12V-2x6 (16-pin) connector melting on RTX 5090 since CES 2025 launch.
- 2Design flaws concentrate current on few pins, producing temperatures up to 150°C and causing housing failures.
- 3Adoptable mitigations include vendor-specific cables, PSU Safeguard features, sensor-equipped L-type cables, and proper seating.
Scoring Rationale
High practical impact and vendor responses, but limited novelty since this is a recurring hardware issue.
