This fan actually pulls air through the case and does not blow into the case. This power supply has additional thermal considerations in the form of the air duct which can be clipped on the top of the power supply around the fan, to direct the airflow toward the heat sink and processor.

It also has a 3-pin, keyed fan connector which plugs into the motherboard and allows the computer software to control the fan. Doing this turns it on or off - overriding the power connector.

This power supply is not backwards compatible with any power supply.
