Reddit mentions of SMAKN DC 5V/4A 20W Switching Power Supply Adapter 100-240 Ac(US)

I was thinking something like these for a power cable:

One of these:

Amazon 5VDC 4A Switching supply

I have the breakout board and picked up this 5v4A PSU from Amazon:

https://www.amazon.com/gp/product/B01N4HYWAM/

(it was $9 on prime when I got it)


To deliver power to the board I found a snap-on right angle molex connector in my parts bin, cut the barrel plug off the PSU, and attached the connector. I don't know the official name for it but this is what it looks like:

So far it has worked great and it frees up the screw down connectors to power accessories. You can see a fan powered there in the second picture.

This one works for mine

The issue may not be the voltage or amperage, but transient variations that drop below or above those required by the Atomic Pi.

That PSU has been reported by at least one other user to have caused problems and I had two regular 500W computer PSUs do the same. You have a couple of options: try another Atomic Pi with that PSU OR try another PSU with your current Atomic Pi. I gave up on two expensive PSU's for a cheap ($9 USD ~ https://www.amazon.com/gp/product/B01N4HYWAM/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1) on all 4 of my Kuri boards with a small power board ($7 USD ~ https://www.amazon.com/Breakout-Adapter-2-5mm-Barrel-Supply/dp/B07RPQN1Z7/ref=sr_1_9?)

TL;DR -- However, personally I use a with a "Filtered" small power board (after several power supply problems) ~ (https://www.reddit.com/r/Atomic_Pi/comments/cmy6ix/another_power_board_design/) that uses a Torroid Coil, fuse, protective diode, and 2 capacitors. Since using the latter board, I have had no issues with any of my 4 boards for months.

thank you very much for the warning / info. Thankfully I didn't plug it in. I ended up getting a 5v / 4a adapter.

Again, thanks for the information!

Found it, looks good! I guess including "barrel" in my search earlier didn't help me. Doesn't say if it's UL listed or anything though.

Amazon has a Prime-able supply for $9 here that looks like it would fit the 2.5mm jack on the breakout board.

​

I don't have the breakout, and had some 2.1mm jacks lying around, so ended up ordering a 5A, 2.1mm supply for $14 that came with an inline jack from Amazon here.

I would go higher than 2.5a

I have had zero issues with this

Obviously, wrong prongs but at that price + an adapter may be cheaper ?

I'm working on an arcade1up mod using linux mint and retropie on the "Atomic Pi" x86 sbc ($40).

It's not easy playing with one hand :)

I have not used those specific ones (I looked at the specs, should be fine), but yes, $18 for 5 is a very good deal!

As far as LED strip those are the ones I got:

30 LED / METER:

(you do not always need 60 LEDs per meter!!)
