  <<<< Note that a PSU with 24 pin can be plugged into a motherboard which has a 20pin connector. The 4 unused pins (black, red, yellow and orange wires) are simply left hanging. There is only one way the connector can be plugged in, so there is no risk of mistake.

This may not be possible if some motherboard components are too closed to the connector. In this case ask for a 24 to 20 pin adaptor or cut the unused 4pin.
