Understanding the Alarming Overheating Issue
The 12VHPWR Connector has become a critical concern due to its capacity to reach dangerous temperatures when paired with the RTX 5090. Recent tests conducted by Der8auer have brought to light that these extreme temperatures are not necessarily the result of user mishandling.
Investigating the Source of the Heat
Startling Discoveries
It was a shock for many enthusiasts to find out that the 12-pin power connector on the RTX 5090 can become extremely hot, even without any user error. Der8auer’s tests revealed that within just five minutes, the connector’s temperature on the PSU side can skyrocket to 150°C.
In-depth Examination
- Der8auer utilized a liquid-cooled RTX 5090 FE with a Corsair 12VHPWR cable.
- Thermal imaging showed 150°C on the PSU side and 90°C on the GPU.
- Proper insertion of connectors suggested that the problem lies elsewhere.
Identifying the Root Cause
Imbalance in Load Distribution
The investigation highlighted that two wires in the 12-pin connector were overburdened, each carrying over 20 Amps instead of the intended 8 Amps. This misallocation led to one wire melting, a scenario reminiscent of previous issues with the RTX 4090.
Cable Quality Dismissed
Despite employing a high-quality Corsair cable, the problem persisted. The Moddiy 12VHPWR cable was also scrutinized and found to be of excellent quality, eliminating poor cable construction as a potential cause.
Recommendations for the Future
The RTX 5090 might benefit from dual 12-pin connectors to better distribute the power load and prevent overheating. This incident emphasizes the urgent need for enhanced power management solutions in high-powered GPUs.
