Hello i would like to ask how much amp i need to power the orange pi pc ? I got my pi yesterday and now been looking for a power supply. I got one here 5v / 1a. What would happen if i power it with only 1a. Will it run downclocked or will the stutter? Is there a possibility that the power supply will overheat due to much power gain ?

Thank you very much.

If you don't have any USB devices attached, I think that 1A would be sufficient... I run one of the OrangePi PC's on a 1200mA power supply and didn't notice any problems.
I think it would just shut down when it has insufficient power.

Though 2A is still recommended.

I use a 3a charger with usb y cable to power a hub(external drive) with which is connected to one of the usb ports.But a quick check with an ammeter should tell the you consumption.

I measure on my OPI pc 550mA with usb mouse and keyboard, running Android image

On load or idle ?
