according to the manufacturer, 5 meters of this strip could draw up to 6 ampere (if you light all pixels maximum white). that depends more on the leds than the controller though, so just check the info from where you want to buy them. i have a power brick that delivers 3 ampere and a program that lets 5 meters of strip light - see my newer blog post. I also use a PC power brick - that delivers more than enough power to keep the 5 volts up with lots of leds.
