Safety notes
- Never mix modular cables between different PSU brands or models. The PSU-side pinout is not standardized — a mismatched cable can destroy hardware.
- Do not exceed a cable's rated load with splitters or adapters, and replace any cable with damaged or discolored connectors.
- Before buying, confirm the connector layout and PSU guidance on the official pages of both your exact card model and your PSU — board partners change designs between variants.
