I am getting my RasperryPi Rev2 soon, and I plan to use it as a media centre. I have a WesternDigital Elements 1TB USB3 2.5" USB powered external harddrive. I know that a normal USB port outputs 500mA, and the Pi recommends 700mA in.
I was wondering if I bought a 1.2A PSU, will that be enough to power the external through the RPi's USB ports?
I was looking at this power supply.
Micro USB power supply adapter,Euro,1.2A
Thank you for your help.
