SPCR

Recently I built a compact pc with intel atom d425 (surfing machine).
I'm using 120w pico psu from ePona tech http://www.epona.com.hk/en/proshow.asp? ... 19&smID=44
with tft lcd monitor 12v 5A ac dc adapter.
I observed that motherboard, hard disk and cabinet gives electric shock.
If I use smps instead of pico psu there is no electric shock.
Yes I know that it's GND related problem but then how to fix it?

You know? Then ground the computer.
Do you have ground in the socket?
The relevant part here is the AC adaapter. Not the pico.
Btw, pico is a smps.

Problem solved...
The culprit was adapter power cord.
