For some reason over the past couple of days the square rainbow icon appears in the top right of my screen.(I have a pi2 btw). Being new to Pi I thought it was dropping wifi connection. But no alas i read its low power issues….All has been fine with power up till now…Including a bit of cheeking high overclocking. It all began a couple of days ago. Ive since detached my wifi, removed any overclocking, removed a little fan from the Pi case and uplugged my keybard and it’s still appearing…More and more now i think. My power supply is 5v 2a…And i can’t work out why this would be the case. Am i low on power really>? even when running a GameBoy game?
Has anyone noticed issues like this and should i ignore it?labelwhoreParticipant02/26/2015 at 22:07Post count: 526
Do you know the power supply is actually outputting 2 amps?leefyParticipant02/26/2015 at 22:19Post count: 29
I can only go on what it says on the label….I bought it as part of a bundle from a reputable Pi dealer. Is there any way for me to check the amps? i don’t have a voltmeter.labelwhoreParticipant02/26/2015 at 22:24Post count: 526
I’d say get one. They’re pretty cheap, and for a project like this, pretty much mandatory. I haven’t run into this issue yet, but given the power supply is so cheap, I’m just waiting for it to happen. lol I usually throw down $30 – $50 for a nice power supply for my projects, the $7 one that came with my PI scares me a bit. :PleefyParticipant02/27/2015 at 14:03Post count: 29
Just as a final note….I have tried a samsung phone power supply now….
It’s 5v 0.7a. Pretty low powered compared to the one i was using but having problems with….And guess what….No more power icons in the top right…Even with 2 joysticks, 1 wifi dongle, 1 keyboard and overclocked to High.
Moral of this story….
If it was cheap(or part of a bundle) it’s probably useless.

I see the small rainbow icon in the top right corner on boot for a moment on a PI2 but then it goes away. Is that normal?vincegunParticipant02/27/2015 at 19:44Post count: 12
Hi, I think I’m getting the same thing that’s being talked about here. It’s a small 4-color box in the top right corner of my screen that fades in and out while my RPi1 is doing anything other than booting or just sitting at the main ES screen.
I’m using a Belkin 2.1amp power adapter. Model: F8J052.
FWIW, my /boot/config.txt OC settings are:

the one on boot is normal as far as I know.neighbourhoodnerdParticipant02/28/2015 at 02:18Post count: 111
confirmed, boot square is normal.
However, if the rainbow square stays, it means your power supply is not good enough. It’s worth buying a decent one.
