Hello retro gamers!
I’m looking for advice on higher current power supplies. I’ve modified my picade with some after market lighting and other additions.
The mod includes 14 adafruit neopixels, a usb audio interface, 8x backlit buttons in addition to the normal picade connections. I’m driving the LED kit directly from the 5 Volt line pre Pi.
With my rather strong 5(.1) Volt supply, I’m finding I’m right on the edge of the voltage warning without any other peripherals attached. The Adafruit Neopixels are tipping current draw over the edge as with them off it’s fine and stable.
I’m trying to establish what route to take from here.
Looking around the usual retailers, the Pi PSU appears to be the most solid supply at around 2.5A. Because I’m on this limit already with existing hardware, this supply isn’t sufficient. I need at least 3 Amps looking at measurements and would probably be best with nearer 5 Volts.
So the question really is, has anyone installed a USB based supply of that current level? (probably not)
If not, what’s the best option in terms of a non usb supply? I want something that isn’t going to catch fire and has good internal construction so it can remain on 24/7.
I have plenty of space inside so I could potentially put a powercon connector or IEC on the back and install a brick inside…
Anyway, any advice is good advice!
