Not exactly sure what cable will connect 12VDC power to the ASI 178MC camera.
Is it a USB 3.0 A Male to Type B as illustrated below.
Thanks

Sorry, images didn't make it the first time. Hopefully this works.
ASI178MC does not need extra power supply since it is an uncool camera and USB3.0 port can support its power consumption. You can connect ASI178MC to ASIAIR USB port as it shows in your picture.
