The LEDs are powered from the 5v Arduino power supply. As long as you aren't lighting up all the pixels full power white that should be fine. You can also solder in the included terminal block (pro-tip: put it on the bottom of the board so it doesn't stick up) to attach an external 4-6VDC power supply. There's a polarity protection FET on there in case you wire the power backwards
