Hi Kon,
As long as you have a 12 Volt power supply, as long as the amperage is sufficient there should be no risk of blowing a board on that count. Even if you have a 100Amp supply, the unit will only use what it needs. Just make sure its 12 Volts.
I have a 6SE which uses the same mount. I use a 1 Amp supply and have no problems. Do you have access to a 12 Volt battery? Your car battery is fine (or a "Jump-Start"). If you still get the error with that, then I would suggest that its not a supply problem but something else.
