Power to 633 ?


New member
I have a WRUSBY03 cable. It works fine but I need to a power cable as well to get it to work. Is that right? I Thought that the USB cable provided power to the display as well. So my question is, is my USB cable broken or is it right that I need both the USB cable and the power?

On the 633, you do need a separate power cable. This is due to the integrated fan controller.
