My power supply uses a power cord that looks like this http://www.sounddevices.com/images/tech-notes/iec-us.jpg and my power strip outlet looks like this http://i00.i.aliimg.com/img/pb/144/449/477/477449144_093.jpg and for me to connect the cable i need a 3 pin prong adapter for it to fit and sometimes i hear static noise from the prong and when my PC is off, if moved my keyboard turns on. What can I do about this problem? Thank you
