If your PS3 will not turn on at all and you don't even see the red light on the front of the system, this part may be all you need. Also if you own an old model like the 60gb and it gets really hot, you can change it with this newer power supply model which does not got hot.

These Power Supplies are universal so they will work on all compatible PS3 units since they can do both 100- 240 volts. I tested iton every model and it worked on every one.
