You can test a power supply by using a specially designed tester like the one in the video where you plug the connectors into it and lights will show if its working or not.
The first video is the removing of the connections to the motherboard and other devices like CD drive.
The second video is removing the power supply its self , it is normally held in by 4 screws.
The first video is the power supply being inserted back into the case and screwed back in.
The second video is reconnecting the connectors like the ATX and the Molex's back to their respective devices.
This is when the new power supply has been connected successfully as the fan starts operating.
