I don't know for sure if it's the power supply I'm using but I am getting under voltage warning on my Raspberry Pi B+ when overclocked and not overclocked (more frequently when overclocked).
I've tried 4 different phone chargers - HTC, Samsung, and 2 off brands, and 3 different USB cables. I've also tried using the Pi without anything plugged into the USB. I am planning on getting a powered USB Hub, because I want to use a wifi dongle along with my Xbox controller.
I just want to know what the consensus is for overclocking a Pi on whether or not it needs a stronger PSU or it's because the USB ports are drawing too much power.
Also, any recommendations for a reliable PSU and powered USB hub?
