Hope you have enough lead in your pencil to boot it up My power supply is in inches rather than volts but still 12 never the lessYeah m8 deffos replace the power supply to a 12v 5/6 amp number, baz advised me on this also and the box booted up for a flash as soon as i switched the new psu on. those little multi voltage adapeters are no use. you need a laptop/strip light type psu to ensure enough power is getting to the box.
