Haven't had any issues with my China 5v 3A adapter -- but I'm not OC'd - try reverting back to standard clock and see if the bolt goes away - if it does you might need to get a larger/better power supply ( I've seen a few reports saying the Canakit supply doesn't actually provide 2.5A @ 5V )
For example this review on Amazon by Chris Satterleeon April 4, 2016 ( https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4 )
He does some Testing and includes a chart which shows it and says :
An interesting point is where the curves cross their rated current values. The Kootek 2.0A supply crosses 2.0A at about 4.6V (2.0*4.6 = 9.2W). The Canakit 2.5A supply crosses 2.5A at about 4.5V (2.5*4.5 = 11.25W). Both of these are well below 5V. Probably high enough that the RPi won't crash, but cutting it close.
Another interesting point is where the curves cross 5.0V. The Kootek 2.0A supply crosses 5.0V at about 0.8A (0.8*5.0 = 4.0W). The Canakit 2.5A supply crosses 5.0V at about 1.0A (1.0*5.0 = 5.0W).
People who are claiming that this supply doesn't deliver 2.5A are correct - if they are expecting it to deliver 2.5A at 5.0V. But what is important is whether the supply is sufficient for the RPi 3. All I can say for sure is that it does deliver proportionally more power than a 2.0A-rated power supply that has worked fine for me with the Gen 1 RPi B+. For that reason, I'm giving it four stars. "
So by the time it hits 2.5A the voltage has dropped to 4.5V which may be the reason the lightning bolt is showing if the case adds even a small amount more of drop by using the GPIO pins for the power in !
You have some hungry sensors. If they are pulling off of the 5V rail on the Pi, then that pulls directly off of the usb power supply with no limiting factor other than the supply. If you are not planning on adding any more peripherals, then a 2.5 amp power supply will work. They are common and you can get them anywhere. Here is one from a reputable brand on Amazon. If you are considering adding more to the Pi, then maybe go with 3amp or more to be safe. Don't go with the 3.3V GPIO to power anything if you can get away with using the 5V. I have read that the 3.3V is limited to 50ma, although I have pulled more without side effects, I think it might cause damage in the long run.
If it was me, I would purchase a Canakit power supply. They give a solid power source to raspberry pi device. I think the c64 maxi uses a micro-usb which I believe 2.5A to be the most it can send. Most likely it only requires as much as the mini. Most likely any quality usb 2.4A brick would work but I personally have to Canakit power supplies and they are great.
Something like this
I have a 3A usb-c one too that I sometimes put an adapter on for micro usb.
What kind of usb power supply did you try? I'm no expert but it might be from the power supply being too noisy with interference. You might want to try getting a power supply with a noise filter like this one. Ive heard of similar issues and that switching to a higher quality power supply did help.
Edit: looking at the reviews for that supply have me questioning if that one really does have noise filtering as is claimed. So maybe this one isnt a good option, but maybe another noise filtering power supply might be good.
I have not run an update yet on the nano. The cable is 160mm according to the amazon page. I was just using a 5V 2.5A micro usb power supply that i saw recommended with it. Should i be using a stronger power supply? I might have a 12V DCin somewhere.
As for a spare raspberry pi, i do not, but since it seems like it could help, i ordered one off amazon that shud come on friday.
Thanks again for the help
you are answering a lot of my questions zombie, as I was wondering about a power supply.
Would this one suffice: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Listed/dp/B00MARDJZ4/ref=sr_1_2?keywords=canakit+raspberry+pi+3+b%2B+power+supply&qid=1560012517&s=electronics&sr=1-2
I saw another canakit power supply, but it was only rated for 1 amp, so I wasn't sure which one to purchase.
The stock one.
I've always found the Pi USB port was able to charge it, I use this power supply for my Raspberry Pi, if you aren't able to charge it it is possible that you're Pi isn't getting enough power to power the USB ports. If the cable isn't allowing charging you may consider switching USB cables, I have a cheap Amazon Basics one and it seems to work fine.
I’m using a Cannakit 2.5A, I previously used a Samsung 2A adapter with a long micro usb, and it didn’t work very well, it would disconnect from the printer randomly in the middle of prints. I replaced the cable with the one from my Fire tablet and that solved it. I got the new Cannakit adapter after that and it’s been working beautifully.
this is the one I’m using currently.
The power supply needs to be a micro USB one (sorry I forgot to mention that). So like a phone charger. I find my Samsung phone charger works fine - it is only something like 2.1A so occasionally I get slowdown (a little lightning symbol appears on the screen which means "Low voltage"), so ideally find a 5V micro USB charger at 2.5A for optimal performance. On the USA Amazon site, this one is good: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4 But if you have a micro USB phone charger already, you could just try it and see if it works.
For the control pads, yeah if they work with a PC through USB then it should hopefully work on the Retropie as well. It's pretty much plug and play - when you put a new controller in, it asks you to press some keys and it is all set up automatically.
Don't know which websites in Canada would be good sorry. Where I am from I just went into a local electronics shop and got everything (Raspberry Pis are actually pretty common, you don't even have to go to a dedicated computer shop).
Canakit pie 3 power supply
5V 2.5A. Basically there are very few chargers (that unwitting folks use for pie power cords) that offer 2.5 amps. I was one. Checked around the house and I didn't have 1 that met the spec. outlet to USB chargers were rated for .5A - 1A. My Samsung Galaxy S7 was 2A. Quite surprising. Run at the right spec and issues melt away. Also don't be too far away and try disabling the Pie's wifi. Have fun with 0 lag.

Sorry for the delay in getting back to you, but this is the power adaptor I use. It works great with the case. If you are having a mating issue with the power port, check to make sure that the pi is sitting correctly in the case, and also make sure that the ends of the case line up and aren't pushed too far one way or the other.
I have done research and this is the one I am getting. It is intended for the rpi3. It is 2x the price of the generic ones but has stellar reviews. Model #DCAR-RSP-2A5 <-----important https://www.amazon.com/gp/product/B00MARDJZ4/ref=s9_acsd_al_bw_c_x_2_w
It's what you plug into the wall to supply your device with power... Looks like this... https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4/ref=sr_1_3?ie=UTF8&qid=1493155225&sr=8-3&keywords=raspberry+pi+power+supply
Thanks for the reply! I am currently using the Canakit 5V 2.5A power supply so it should be that. Is there a tool I can use to check if the Pi is utilizing the full power of the supply?
my Pi 3 was struggling with the "2.5A" power supply that came with my case/heatsink/fan kit; constant low voltage warning when under load. Picked up this one been running great ever since.
This one will power the Pi 3 without any issues whatsoever.
If you're looking for an alternate charger, you want 5V at 2.5A for the Pi 3. 2A would probably work but 2.5 is what you want to be shooting for.
Most off-the-shelf microUSB power supplies are going to be 1 to 1.5A, some even 500mA, because that's what most microUSB devices take (like cell phones, etc.). 2.5A is kind of "non-standard" and I've only ever seen a couple of power supplies that deliver that kind of power.
This one powers the Pi 3 perfectly.
If you choose not to go with that one, you'll need to find a microUSB adaptor that is 5V 2.5A, which aren't very common.
The power supply that came with my RPi3 kit caused undervolt issues almost immediately. I replaced it with this power supply and it's worked fine ever since. My advice is, don't ignore undervolt warnings. Also, test the new power supply with a multester before using it to be sure it's outputting to spec.
I do not have that issue.
CanaKit 2.5W Power Supply: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4/
If this is the one you got, I would try getting another one (from the link above) for the $10. You may have gotten a bad one. If it is still happening, I would swap out the Pi ($36).
I have a Cannakit adapter. This one, to be exact: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4
Before I bought that I was running mine with a 5V 1.9 Amp supply and while it did have some slowdown it wasn't anything like this. Most everything ran fine.
People seem to have success with the Canakit one: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4
You could also go to any gadget/Apple store and buy an iPad charger. For your workload of a Pi and one connected device that will work fine.
Yep. I have the 5V 2.5A https://www.amazon.com/gp/product/B00MARDJZ4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
It never gets that hot doing anything I have it doing. Cooling I do not believe will resolve the freezing/pausing issues. As I showed above the freezing happens even when it's at 40'C-50'C. :/
Thanks for the help though!
The rainbow square indicates that your power supply is inadequate.
The recommended power supply for a Raspberry Pi 3 is 2.5A (which is higher than previous Pis, like the Pi 2) -- you're likely using a power supply that is lower than that.
Here's a good one for powering the Pi 3.
I just buy this one every time. It works fantastic with every Raspberry I've ever built, plus Amazon prime FTW.
Is wattage the only thing I need to worry about then? I was aiming for correct voltage, probably a very novice mistake.
Edit: found this https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4/ref=sr_1_14?s=electronics&amp;ie=UTF8&amp;qid=1466353372&amp;sr=1-14 could I just hook this up to a dummy battery like in my diagram?(and probably also a potentiometer) It actually seems a lot easier to do it this way.
Raspberry Pi 3, running Openelec, runs pretty flawlessly, and you only need to supply a power supply (2.5 amp version), and a microsdhc card. The Raspberry Pi 3 can use your tv remote with HDMI-CEC, so you don't even need a secondary remote control for it.
It's a joke from the movie "Bull Durham": https://www.youtube.com/watch?v=Fo88LaJIt5E
As for power supplies, you can get away with, like, an old phone charger, but it's better to buy a dedicated power supply that puts out a good 2.5A. The Canakit one at Amazon is good: https://smile.amazon.com/dp/B00MARDJZ4/
And again, you can get away with using the extra space on the micro SD card, but a thumb drive handles wear better, and they're cheap online this week.
I'm using the original one that shipped with the Pi 3B+ here: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Listed/dp/B00MARDJZ4
Is that not be enough for OctoPrint?
For a Pi 3
For a Pi 4
Yeah, honestly the best way to power a pi is with the official power supply. Add a second power supply for your lights - it's hard to recommend one without knowing how much power you need for your LEDs.
I personally use canakit's power supply which is slightly less expensive. They also sell their items through Amazon.
I use this one.
Get the official one
I have used, overclocked, abused, and gamed with every Pi ever released
I always use the official one and have no power issues
I'd swap the power supply for a new 2.5 Amp one, get a good quality one and avoid anything fancy.
Looks very similar to the CanaKit supply aside from the 5.25 output voltage and not having a noise filter ferrite on the power lead.
Power adapter I would say get the canakit for the rpi3b+
I have a case from wish that I spent 2 bucks on. So that’s totally up to you. If you plan to use it heavily I would say get some good fans and beat sinks
iUniker Raspberry Pi 3 B+ Dual Fan with Raspberry Pi Heatsink, Raspberry Pi Fan for Raspberry Pi 3B+/Pi 3 B/Pi 2 B https://www.amazon.com/dp/B07D5WWNH6/ref=cm_sw_r_cp_api_76qMBbD640R1H
Then get a new memory card and download the Retropie image and flash it using something like applepibaker.
For the cost of two coffees you can get an official power supply. Seriously, it's only ten dollars, there's nothing to be afraid of...
I have two of these: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4
It can't hurt to try raspbian, but if you've tried different OSen already, it looks like a hardware issue.
You mention multiple power adapters, but what sort? Cheaper power adapters and USB cables often have very thin conductor cables that prevent sufficient power from reaching your RPi. The output of the adapter won't matter if it can't reach your RPi. You need a quality power supply with thicker gauge cables. The RPi 3B requires more power than the USB spec provides, so a lot of "standard" USB solutions won't work well. I recommend power adapters from Adafruit or Canakit which provide both thicker 20 AWG cables, as well as a tiny bit more voltage. These have been designed specifically for the RPi, so aren't bound by the limitations of the USB specification.
If you're confident of your power adapters, do you have anything plugged into the RPi? If so, try booting with nothing plugged in save the display and see if it gets any further.
The answer is: it depends.
If you just want it to sit there not doing a whole lot without much hooked up to it, 2.4A might work. A power adapter that will for sure work is ten bucks.
retropie-4.2-rpi2_rpi3.img. The power supply I bought has those exact specs
My research shows this is the best power supply: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4/ref=cm_wl_huc_item
As others have mentioned, a micro SD and an adapter are necessary as well. I'd also recommend this power supply for guaranteed 2.5A, though the one you already have may be very similar: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4/ref=sr_1_3?ie=UTF8&qid=1498077621&sr=8-3&keywords=raspberry+pi+3+power+supply.
What I haven't seen anybody note, though, is that Buffalo offers newer controllers that also happen to be cheaper: https://www.amazon.com/gp/product/B06XWD8QQJ/ref=s9_acsd_hps_bw_c_x_2_w.
I think so. I'm using this guy.
Permanent cable, 5 foot long.
Its this adapter here: https://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4/
Any decent microSD storage will do fine as well.
I normally use the Adafruit power adapters, but the Canakit unit on Amazon gets high marks too.

That's what I was starting to think. Should I get this one?
Solely between the two, I would say get the first one (5.25v, 2.4A). The raspi is very sensitive to small fluctuations in power, so I recommend a power supply with a ferrite bead (the thick cylindrical thing on this cable)
Here's the power supply I've been using for the past few months (amazon). If you're not getting a starter kit, I'd recommend this as your power supply.
This $43 kit is a link to a <$50 "bare essentials kit" on amazon. My reddit secret Santa actually sent me this kit last week: no complaints(:
this $50 kit is the same as the above, but includes a case
Unless there is a specific reason you want a 2b+ i would just buy a pi 3 model B You can current order a pi 3 from thepihut.com for £30.00 and then order your case and what not from them too or buy your case and stuff off amazon. things you will need beside the board
Class 10 SD Card
optional but recommended case
price total: around $55 USD
Edit* changed link to correct SD card for a pi 3
Since other people have answered your question. Here is a very good, cheap, power supply for the Pi 3.
CanaKit 5V 2.5A Raspberry Pi 3 Power Supply - $10.
What are you using for your power source? I've had a similar problem, once I switched to a 2.5a power source it went away.
Here's what I use: https://www.amazon.com/gp/product/B00MARDJZ4
Tablet charger is probably fine. I'm not aware of an "official" charger. I bought this one though: http://www.amazon.com/CanaKit-Raspberry-Supply-Adapter-Charger/dp/B00MARDJZ4/ref=sr_1_8?ie=UTF8&qid=1458158418&sr=8-8&keywords=cana+kit
Side note, I spent $50 shipped on a PI3 from Adafruit, $6 on a 8 GB uSD card, $10 on a power supply and $5 on heat sinks. $71 total. I'll need to print an enclosure for it. In hind sight, I wish I had spent $75 on this: http://www.amazon.com/CanaKit-Raspberry-Complete-Starter-Kit/dp/B01C6Q2GSY/ref=sr_1_2?ie=UTF8&qid=1458158418&sr=8-2&keywords=cana+kit
To power it you only need a microusb cord that should have come with any android phone, but a 2A is highly suggested for properly working like this one.
To hook up the raspberry pi model that will fit that case to an older tv you will need a A/V to RCA cable like this, and you will have to change the setting on the pi to default a/v out of the port instead of hdmi.
And finally that case should work fine.
Also I think there is only one SD card port on that model and that is where the OS will go, if you want to watch shows from a non-internet source will have to put the media on a usb drive and plug it into the pi. If you just want to use it to watch stuff I would suggest using this OS which is made to be a media center.
No rainbow block at the top right. I am using a 2.5 amp psu
And the Pi is here
The img file is retropie-v3.0-rpi2.img.gz and it is 740,874 KB in the conpressed folder I downloaded using bittorrent. extracted it is 2.04 GB
for the cpuinfo:
CPU revision : 7
Hardware : BCM2708
Revision : 0010
Serial : 000000009934b231
Emulations are working and it boots into ES
My answer always seems to be a raspberry pi 2 in these cases.
Use this 2.5a power supply, a microSD card for boot, a flash drive for the OS, and use the rest for the biggest external drive you can find. I prefer OSMC but openELEC works just as well. It's possible to power a portable HDD from a USB port on the pi but I don't know what kind of capacity they are at and I can't imagine they'd be cheap. Oh yeah, if you don't know the codecs that your files use you may end up with files that won't play. The MPEG-2 and VC-1 codecs should take care of most everything else.
Creative people know how to put the hardware in one neat little package, not me.
So it appears that it does say 100-240V AC and 50-60 Hz on the cable. Here is the model on Amazon. After the input Hertz it also lists the amperes at 0.5A. The output is 5V and has 2.5A. You can actually see it in this image if you zoom in.
Does it seem like it would be fine then to just add an adapter? Is the output important when plugging it into a socket, since basically I will only use it to power up the pi?
I unfortunately have limited knowledge of electrical things, so I guess there is no better time than now to learn that.
Thanks for the tip. Like I mentioned to others on here, I was able to SSH and visit the WebUI at one point. Another user had mentioned the SD card as well. I might start there. I will ask around on other subreddits as well.
I didn't see it looking through the FAQ, but is there a list of known bad players for SDcards and power supplys? My PiZ uses the CanaKit RPi supply with the power filter. Not sure what kind of SD card I'm using, but it was likely bought from MicroCenter and formatted with balenaEtcher.
