I recently purchased a jamma x from the mister Eu page it’s works fine on the pc but when I go to plug it up to my sega new Astro city it doesn’t power on at all and the blue light where the power supply is from the wall goes is blinking blue ? I thought the jamma was suppose to power this ?

Do I need more power can I up the voltage ? If so how do I turn up the voltage for a sega Astro city psu I had a sega psu 400-5198-01Z

Any help would be appreciated.

Jammix should be powered just fine over the JAMMA edge connector. It could be overvoltage or an issue with the connection, I would check the orientation/fit of the connector and check the 12v PIN from the power supply.
