    I'm new to the site and I plan on making a console out of a broken Retron 1. I would like to use the power and reset buttons already on the console, I would also like to install a fan on the inside for overclocking. I can find instructions online for only having one or the other, but not for both. Can anyone give me a hand with this? Any help would be much appreciated.

        I actually bought a 2.5amp power supply with an on/off button off of ebay. Works beautifully. Unfortunately, not being sold anymore. Didn't get this specific one but it should work:

        Pi Model or other hardware: Pi3B
        Power Supply used: 2.5 amp power supply
        RetroPie Version Used: 4.2.10
        Built From: Premade from Retropie website
        USB Devices connected: 4x ibuffalo snes controllers

          Many ways!

          • A power supply with a switch on so you can power down the unit after you've done your safe shutdown.

          • Power the fan from the USB port so that it goes of with the Pi.

          • One of these circuits that will shut off the power to the whole device a couple of minutes after the shutdown is initiated (although you might need a new case):

          https://www.msldigital.com (they have a riser cable to get it away from your fan too)
