I’m looking at some of the various pico psus from around the internet and it is dawning on me that they don’t appear to be supplying the typical compliment of voltages we usually see from the atx standard..
Can someone confirm?
Any out there that have more voltages present than others? Which is the best one?
Issue is poorly documemented what voltages is genrated via Pico PSU. Is it all 5V generated and no else? Does it generate bit of -12V as well for the audio and serial port use?
Pico PSU gets power from 12V supply and supplies pair of 3.3V, 5V via DC to DC converters, -12V via a linear regulator around 100mA usually. The 12V goes straight through via a mosfet switch.
The most of watts comes from 5V. The inductor size does determines the watts. The size you see for 90W is actually less.
And they are low quality clones from original pico PSU decades ago. Was created to help people create in-car computers.
This is original design.

Manual clarifies what power are generated and what is not generated.

Pico PSU is primarily made for itx boards with low power up to 65W processor.
