Does anyone know if there is a way to disable power going to my USB ports when the pc is off?

My motherboard is a Asus H81-plus, thank you.

If there isn't any BIOS setting I doubt there's anything you can do software-wise. Could try wiring your LEDs to a molex connector from your PSU instead. Pin 4 (red wire) is 5V, same as USB. But I believe that 5V rail should power off when your PC does, wheres as the USB ports are connected to the 5VSB rail, which stays on.
