Newly purchased ClockWork Pi will not power on

The sd card should come with the system loaded. @Morzhar, please follow instruction on topics like this:

First rule out assemble and cable connection issues, try power it on by USB only, then try that reset button on the mainboard, if problem persists, try re-flash the system as @kekoponte suggested.

Finally, if none of the above helps, write an email to help@clockworkpi.com, we will help you get a replacement part.
