Power Supply Wires Tags: Power Supplies Power Switch Components Last response: June 15, 2001 12:41 PM in Components Share jp1114 June 13, 2001 12:36:58 PM 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 Pat More about : power supply wires hollett June 14, 2001 7:49:52 AM This is a standard dual polarity switch found on most old AT computers.
