Enough power for a USB HDD?
In your description you state "This PSU supports up to 2.5A of current, so it won't let you down when powering hungry devices through your Raspberry Pi 3 Model B". Does that extend to powering a portable USB HDD? It was always received wisdom that you needed a powered hub with earlier Pi models. Is this no longer true with a Pi3 and this power supply?
Alan Tucker
  • The current rating of the PSU and the maximum current output of the Pi's USB ports are two seperate things. The Pi3 can output a maximum of 1.2A across all 4 USB ports (and the GPIO I believe). So whilst the power supply offers plenty of juice for the Pi3 to run at full capacity, if the external HDD needs more than 1.2A to run effectively then you will need a powered USB hub with a higher current output. With HDDs it's usually best to run them via a powered hub, unless you are looking at ones that have been specifically designed to be low power, like these- https://www.modmypi.com/raspberry-pi/accessories/western-digital

    Hope that helps and makes sense!
