I'm trying to connect my RX 9060 XT graphics card to a Thermalright power supply. The cable I have is labeled "CM-PSU," which may indicate it was made for Cooler Master modular power supplies. An AI assistant warned me that the PSU-side pinout may not match, even though the GPU-side PCIe connector looks standard, and that using the wrong modular cable could damage the graphics card or other components. Is this cable safe to use, and what should I do instead?

Only use the PCIe power cable that came with your Thermalright PSU, or an exact replacement specifically listed as compatible with that model. Modular PSU-side connectors are not universal, so a cable from another brand—or even another PSU series—can have different wiring. Don’t plug in the cable labeled “CM-PSU” unless Thermalright explicitly confirms it is compatible with your exact PSU model.
The safest next step is to check the PSU’s exact model and its manual for the included GPU cables. If the original cable is missing, contact Thermalright or buy a replacement made for that specific model. The connector fitting physically does not prove that the wiring is safe, so leave the questionable cable disconnected.
