Gen2 case gives shock

[Gizmob]

Just got my gen2 case and its great. When I  went to move it when the pi3 was on and I got a small electrical shock.  The shock shut the pi off.  What would cause this?

[jason]

there are posts inside the case that should touch the pi's pcb's. They should have exposed metal in this area, which is connected to ground, which would ground the case.

The pi community didn't do this, it's plays to their inexperience with hardware.

the USB connectors from the pi should also be touching the exposed metal on the inside of the case. Perhaps this is not happening. Try getting some sand paper and sanding down the inside of the case that touches the USB. Perhaps some of the metal's paint is blocking conduction.

You shocked the case, and that charge found it's way to a component, and the pi shut off due to either that component failing, or an over current protection. 

Most of the components are able to withstand ESD, however, it's not ideal if this happens a lot. Keep us posted.

If I take the pi out will I need I new thermal pad?

 

[jason]

nah, it should be okay, but if you do, not to worry, I'll get you more.

Plugging it back in now lets see if sanding did the trick

Still shocks but did not shut the pie off but nothing worked and had to reboot

Can you see the metal from the USB touching the case?

[jason]

It could also be your power supply, perhaps that's not properly grounded.

[Gizmob]

It does not look like the usb are touching 

[jason]

okay, how bout the HDMI, that looks like it touches pretty good. Specifically the bottom of the connector. Try sanding that part of the hdmi port to expose some metal, that's definitely painted.

[Gizmob]

Sanded the HDMI still shuts off but there is no shock atleast that I can feal

Power suppy is the one that comes in the canna kit and plugged into a powerstrip

Figured it out.  Before I bought this case I did alot of research.  I found its good for overclocking. I apologize I did not even think that would cause that but it did.  I lowered the over voltage and it solved the problem.  Thank you for all your help.

Most likely a combination of all the above.

Do you know if that's a decent power suppy if not any recommendations 

[jason]

Not really. It's tough to say because the latest 3 uses so much power, that the supply needs to overdrive a bit because of the loss in the cable. So you could be better off with a much better cable. The one's from thepihut are good, I think they use the officially recommended version.

I ordered the officil PSU so I hope that fixes everything.  Good news is no more shocks.  Bad news is now I get constant undervoltage warnings that I never got before.  I even started from scratch by formatting my SD card and doing a clean install.  I am hoping its all due to a bad PSU.  Do you know if the shock could have caused damage to the pi3.
