1. Is there any risk of getting electric shock?
No! There is no risk of electric shock in the Paper Clip test. I have personally touched paper clip and it’s totally safe.
2. How many volts are running down there?
In a 24 pin connector, there are different color wires which carries different Voltages. Yellow wires should be 12 volts, red 5 volts, orange 3.3 volts, blue wire -12 volts, purple wire is the 5 volt standby. These voltages are too low to cause a electric shock.
