Salvete! I recently purchased a USB 3.0 hub and, since it didn't come with a power adapter, I acquired one separately. I am attaching it to a computer with a low-output power supply, so it is necessary that the USB 3.0 hub provide its own power.
How can I know that the USB hub is drawing its power from the adapter and not the computer (without blowing the power supply on the computer)?
The adapter outputs 19v to the hub at 6.3 amps. The computer's power supply brings 500 watts.
How can I test this?
Is it possible to measure the power output and source with some sort of software? Really, I am at a loss here.
This thread is interesting, if anybody is following my question.
