<a href="http://imgur.com/a/46Ofo" rel="nofollow">screenshots for 12V, 5V, 3.3V and 12V with a twist</a></p><p>Summary: A 5V version would actually require more total power, and waste more of it, at least in the strip (not to mention extra resistors). How the PSU's own efficiency at 5V vs 12V affects things is a (shoo, sparkghost!) different matter.</p></p>

PC power supply puts out a lot more current at 5V than 12V, and a lot less power wasted.</p>

Although there's no voltage rating stated, it looks like you give these strips +12V and then pull the lines for the color(s) you want to ground. These strips can be cut into any multiple of 3 LEDs. A full 5M strip would pull about 6A at 12V with all LEDs on full.</p>
