Interesting, it is sold as 2A, but has 3A printed on it... still I assume that 2A PSUs do not supply enough power.  
Hi, 
I'm using a 2A power supply (from here) and all works properly. 
Edit: As Steven says, I don't use the mini USB but a yellow Jack cable to power the board. I have also a class 10 SD card.
