+## Check Power Supply Rating
+Using an USB attached SSD can draw quite some power. For instance on Raspberry Pi 3 the official Raspberry Pi power supply (PSU) only provides 2.5A which can be too tight. Use a power supply which can at least provide 3.5A. Alternatively use a powered USB hub. Connect the Hub to one of the USB slots of your Raspberry Pi, and connect the SSD to the Hub. The power supply that came with the Hub will power the attached device(s).
