Corsair has introduced a new power cable designed to prevent GPU burnout caused by loose connections. The ThermalProtect 12V-2×6 cable uses a passive bimetallic thermal switch that disconnects the circuit when the wire temperature reaches 65 degrees Celsius plus or minus 5 degrees. The switch is located 30 millimeters from the GPU connector inside a cable comb.

The cable is compatible with any brand's native 12V-2×6 power supply and GPU, and it is backward compatible with older 12VHPWR interfaces. However, it does not support 2×8-pin to 12V-2×6 adapter cables. Corsair states that the mechanism is completely independent of software, firmware, PSU controllers, or GPU vendor support.
In testing with an RTX 5090 at 60 degrees Celsius ambient temperature and a 3-millimeter cable gap, the ThermalProtect triggered a shutdown in under 1 minute 20 seconds when the wire temperature reached 115 degrees Celsius. Corsair notes that even the updated 12V-2×6 interface still carries a risk of loosening and overheating over time.
Corsair has not confirmed pricing or availability for the ThermalProtect cable.
