Off yes but on no, when you initially press the on button you short out 2 pins on the MB header (the +5V stand-by supply from the PSU) this in turn activates the +12V power supply from the PSU.
Can I use this switch to turn the pc on and off and leave the tower on/off switch in the on position and ignore it.
It is for emergency shutdown or to prevent accidental activation (by curious children etc).
what is the purpose of the on/off switch on the back of the pc near the power cord receptacle?
It is possible that it is the PSU that has an issue and not the on off switch so both need to be checked out.
