Pico DC/DC 12V to ATX:: 160Watt at 15/30 euro?!?
<< < (5/5)
Nominal Animal:
Note that the M2-ATX can provide 8A at 3.3V, 8A at 5V, and 8A at 12V, from 10V to 26V (it's an automotive PSU), with 1.5% regulation on 3.3V and 5V and 2.0% regulation on 12V.  It has a different form factor (you use an ATX-ATX jumper cable between it an the motherboard), having a 160mm × 45mm board, but depending on the computer enclosure, can be easier to mount in a place it gets some airflow.

(120mV of ripple at 12V, assuming you meant peak-to-peak, is only about 1%, so I am not saying you need an M2-ATX instead of a PicoPSU at all; the 120mV ripple on the 12V line is something a generic ATX power supply can have, and still be within the spec.  But, if you do intend to draw 6A from the 12V line, it might be prudent to ensure good airflow, and it is easier for this form factor than PicoPSU form factor, unless you have plastic baffles to direct airflow.  Just wanting you to know of the alternatives here.)

The reason I used links to CarTFT.com is because it is in Europe and has manuals and/or datasheets with detailed information (current limits, ripple, etc.) in the Data sheets and downloads tab.   But lots more shops sell these.
