Hi all, I'm building a new PC with this power supply; iRGB Plus 1050W. My mobo (Asus ROG Maximus Extreme XI) only has two USB headers on the mobo which are already taken by an RGB and a Fan controller. Can I use a normal USB cable and connect it to an external USB port? (note; I'm not worried about the wiring here) Using a mini-usb B to a usb-a (3.0) cable? Thanks.
