Hi there, got my ROCK64 today, whithout power supply beacause I found one that may be suitable in my stuff...
I seem to have powerup issue with it (no led after pluging supply and pushing power button). My power supply is 5V (center positive) with max output 3.5A. Do you think th output is too high ?

thanks,

There is a green led that is connected to the power socket that will illuminate when plugged into power.

The A(mperage) could be 100A and it wouldn't matter, it's the voltage (i.e. pressure) that can cause damage. As long as the voltage is 5v (+/- 5%) and correctly polarized (i.e. centre postiive as you indicated) it should be fine. If you plug in the power, and the green LED between the DC jack and IR sensor doesn't come on, you either have a faulty board, connector or power supply.

Yes that was what I was thinking but was'nt much sure. The power supply does power correctly the usb hub it was made for, but still I will buy another power supply to be sure...

Thanks,
