Chunger... My PSU internal layout is a little different from the pics shown in this thread (APEX 460). My transformer was secured onto the circuit board...which I'm sure was attached to some sort of ground. The power cord input ground wire was secured by bolt screw through the transformer casing into the circuit board. It looks like from the pics in this thread that the PSU power cord wire is grounded to the PSU outer casing. Is this so? Can I ground the lead wire from the power cord input to the PSU outer case? Thanks in advance for your advice.
