How to increase voltage of USB ports on my desktop?

I've been running into an issue where certain things that take lots of power don't work.

For example, when I plug in my laser printer, I get an error in Windows saying something about not being enough voltage and it cannot run my device.

I have multiple monitors hooked up on my usb ports as well - and sometimes, one or two will start flickering like crazy until I reboot.

I feel like I need to somehow increase the power of my USB ports or something - I'm not exactly sure as I've never had this issue before and it's a new problem that started happening recently.

Does anyone know how to approach this and how, or if, I can make my USB ports more powerful?

I can't seem to find much online about this issue, or at least not a concrete solutions, but it does seem like others have this same issue when their USB ports are "overloaded" for lack of a better word.

Thanks everyone!
