I got everything working flawlessly with a different power supply: 5.2V, 3A. :)

@melbmatt50 said in Retropie power switch: As I mentioned before many of the emulators I am not sure if you can program a hot key to escape back to the main retropie menu like you can in mame4all more or less any default emulator in retropie should do this by default. there should be no reason to unplug the pi to turn it off whilst retropie is running.

@urko948 Use the official Raspberry Pi power adapter or whatever the Raspberry guys recommend.

I have had no issues with this power supply and I'm overclocked. Just an update to reclaim my thread. ;) This has been working just fine for me. Haven't seen a lightning bolt since I started using it. Only hardwired 3A cables for me from now on. Thank you all for your suggestions. :)

@creativename i only use the canakits except in my pistation build which need to run a hub and a hdd off of the same power supply and the canakit isnt enough. I use two canakits on my apple iie pi.

@dankcushions I've personally never had any issues with canakit chargers but I also don't overclock

I posted this on a different post but Hey guys iv been playing with issue for a little bit and was thing how was the power getting to the pies motherboard and think its getting its power from the usb port and the 5v fan pins. This had me thinking a long time back I connected a usb powered hub to one and found that the pie stayed on even if I disconnected the power from the pies micro usb port, but the under voltage symbol work come on and the machine would start to run very slow. So what iv done is solder to wires from the nespi case power and reset switch circuit board( theres 3 pairs positive + and negative - wires coming on and off it) I used the middle + and - to run a wire to the pies board (had to solder wires to board) positive + PP2 and negative - PP5 points on the underside of the motherboard near the micro usb port. This seems to have fixed the problem so I tested the pie by running 007 golden eye for the n64 (had the left dpad stuck down so the character would spin around over and over) for and hour and then tried Mario kart 64 (did the same thing with the buttons) for an hour then tried G-police 2 for the ps1 (same again with the buttons) for an hour I dident get under voltage fault. So I hope this will help im going to buy a few more nespi cases and try with them to se if it works with them too. Hope this helps

@edmaul69 yeah thats rly weird idk what to do any more but i do rly want to play it but im not since i cant have fun with that lag :( anyway i send you email u ask me to in other thread heh

@lostless It's a direct plug. so there are no wires. @rbaker Holy crap. :)

It's hard to say if you have the proper power supply. Maybe check your power cable. I use an extra long one and keep that in mind when I am troubleshooting. Maybe your Pi or new power supply is malfunctioning. Do you have a second Pi to test your current card? Since it's global it sounds like you might need to do some additional troubleshooting. I would almost reinstall with a fresh image on the SD card (or a different one) to rule out the SD card, image & configuration. Maybe a different USB drive if that's what you're using. It seems there's a lot that could happening to make a determination or if it was a larger/build related issue more would be posting.

Perfect. Thanks!

cable extensions wont draw any additional power

@crono141 No worries. Had a quick look at your set-up and it's complicated alright... I hope you enjoy troubleshooting!

Have you taken apart the hub to look at the workmanship? Where was the power cord soldered to? Is the Pi being powered from the hub internally?! It could be a lot of things. Take it apart and post up some photos and we can try to help diagnose.

@Alwaysbored612 said in Newbie Needs Suggestions: Are most people using external speakers for similar builds? If so, how do you route the power through the Pi? USB maybe? Do you have a suggested product that works? Don't route the power through the pi. Get a power brick with 5 usb ports on it rated at 3A then from that you can power usb speakers, led lighting and anything else. Use a separate power pack to power the Pi. Se my speakers here. Just a cheap set from Amazon, ripped apart. Really good quality.
