Hey,
So Im new to arduino and I don't even know what im doing. But i wanted to add RGB lights to my PC. I had a arduino nano and left over 5V led strip laying around so why not. Programed lights to fade from color to color. Connected arduino 5V and GND pins to my PC mother board. everything worked fine but i wannted to slow down fading. plugged in MINI usb cable and I saw that light got much brighter. So my question how to make my led strip bright as possible using those pins and not MINI cable? 
P.S power coming from mobo (mother board) is 5,16V.
To which pin did you connect the 5.16V?
There is written 5V and close to it is GND.
