Your PSU should be okay to use if it appears to be functioning normally after the incident. PSU cables are designed to handle the rated voltage and current, and they have various protective mechanisms to prevent damage from minor issues like reversed polarity. If the PSU is working fine and there are no noticeable problems, it's likely safe to continue using it. It's possible to purchase replacement ARGB cables for your PSU, but finding the exact replacement may be a bit challenging, as these cables can vary between different PSU models and manufacturers. You may need to contact the PSU manufacturer's customer support or look for third-party replacement cables that are compatible with your specific PSU model. Be sure to provide them with your PSU's model and other relevant information to get the right replacement. Using the PSU's ARGB header should be safe if it's designed to connect to your PSU's internal components, like cooling fans or lighting, and is not meant for motherboard connection. PSU ARGB headers are typically used for controlling the RGB lighting within the PSU itself and are not meant for motherboard synchronization. However, you can still control the lighting with the switches on the back of the PSU, as you've mentioned. While you may not have motherboard control over the lighting, it's a safe and functional alternative. In summary, your PSU should be fine to use, but make sure you use the proper cables and headers in the future to avoid similar incidents. You can look for replacement ARGB cables specific to your PSU model or use the PSU's internal ARGB header for controlling the lighting within the power supply unit.
