question about the raspberry pi
-
i have a 3b+ using retropie. Can i hook up the monitor to power it up by using the pi as a usb power source? or is it too much power on the pi? i want to use a mini power switch button connected to the pi so that both will turn on when i use the power button.

@r4izuk0 I'm unsure if you mean powering the RPI from a monitor or the monitor from the RPI. Sorry but your wording is not all that clear. Sounds like you mean powering a monitor from the RPI but it's impossible to advise without more details sorry. What monitor?

Maybe I read it wrong first time - it does look like you mean running the monitor from the RPI? It's possible for a small screen if it's 5v and draws 500mA or less (usb2). But I'm not sure that's a good way to do it. What are you trying to achieve by wanting to do it this way?
Actually you can probably draw more (see "FAQs - Raspberry Pi Documentation" https://www.raspberrypi.org/documentation/faqs/#pi-power) if the PSU is up for it, but powering a monitor is best done separately really.
