If i clip my anti-static wrist strap to my power supply and my power supply is plugged into the socket i can be grounded, can i still be grounded if the power supply is plugged into a power board and the power board is plugged into the socket with an extension lead? The power board is a surge protected one and it has a little red led that says grounded so that might make a difference. Thanks :)
 


Just clip it tp some bare metal on the case.
