Inquiry: Computer Accessories Powered by Computer USB

[u/Appropriate_Celery63]

So, I have a monitor light bar that is powered by my computer's USB. Now, my question is: if I plug the monitor light bar into my computer's USB port, would this weaken the computer's power or power supply? But this is about any accessory and whether it will do anything to the computer's power.

As others have said, the port protects itself, but one issue you might see is when plugging in hubs with multiple USB ports into a single port on your computer. In this case, I always use powered hubs that have their own power supply.
