A friend of mine asked me why there are 4 wires (Black, white, brown and blue) coming out of the power supply (connecting to the power switch) instead of just two wires. I have no idea. Any ideas?

Thanks

This is a standard dual polarity switch found on most old AT computers. This is done to enable both Positve and Neutral to be disconected with one switch.

Only the insane prosper.
Only those who prosper can judge what is sane.
