CORSAIR ThermalProtect 12V-2x6 Cable Power Supply Compatibility

We recently released the CORSAIR ThermalProtect 12V-2x6 600W cable. It’s a 12V-2x6 cable that features built-in OTP (Over-temperature Control) that monitors the temperature of the cable itself and shuts off power to the GPU if the cable gets too hot.

This cable addresses an issue where recent GPUs draw very high power, which can cause the cable to overheat and lead to damage to the cable, PSU, or GPU. ThermalProtect is an entirely passive in-cable design, meaning that it does not require a specific PSU, GPU, or any sort of software or firmware to function. As long as the GPU and PSU use a native 12V-2x6 connection, this cable is compatible.

To be absolutely clear, because ThermalProtect is an in-cable design, it is compatible with any power supply with a native 12V-2x6 connector and any GPU with a 12V-2x6 connector. It does not matter which brand the PSU or the GPU is.

How it works is quite simple: If the temperature sensor detects that the cable’s temperature has exceeded 65°C, it will send a signal via the sense pins (the small set of four pins above the larger pins) to the GPU that tells it to stop drawing power. We explain this in more detail in our main ThermalProtect article.

Here’s a list of CORSAIR power supplies that have a native 12V-2x6 connector and are therefore compatible with the ThermalProtect 12V-2x6 cable. This list is accurate at time of publication, and any future PSUs with a 12V-2x6 connector will inherently be compatible with ThermalProtect, too.

Again, if you bought your power supply from another manufacturer, as long as it has a native 12V-2x6 connector, it will work with the CORSAIR ThermalProtect cable.

The ThermalProtect 12V-2x6 cable also has high contrast connections, so you can easily see if the cable is fully inserted or not.

In this case, the ThermalProtect cable is not compatible, and you should not use an adapter cable to integrate the ThermalProtect cable into your PC.

However, we will be releasing ThermalProtect cables for Type 4 and Type 5 CORSAIR PSUs soon. These will be 2x 8-pin to 12V-2x6 cables with built-in ThermalProtect in-cable OTP.

No. 12VHPWR refers to a difference in the sockets of the connector on the GPU and PSU. The pins and connectors on the cables never changed. So if your PSU or GPU has a "12VHPWR" connection, ThermalProtect is still compatible. Our 12VHPWR vs 12V-2x6 article explains this in detail, so read that if you want to learn more.
