I'm also looking for some information. In light of the discovery that the A300m will work on 12 volts, I tested my vega nano and it also works with only 12 volts (I disconnected the 5v from the riser) I am rethinking the power supply for my system. Rather than use the Dynamo 360 and an HDPlex 400w AC-DC I could use a Meanwell SE-600-12. The power supply was already going to be external so it size isn't a problem. Does anyone have experience with Mean wells?
Efficiency isn't very good on that one, only 83% efficient.
Take a look at the EPP-400 and EPP-500, these are more like 91% efficient. I know EPP-400 is in spec (and I use one to run my desktop!), EPP-500 is out of spec for ripple but might be usable with TheHack's ONE2 distro board or something similar that can clean up the ripple. Ideally you should make your own enclosure for these for external use, and they'll need a fan for full power.
If an external PSU enclosure can be done well enough with PETG / ASA plastic then I might be able to help design and 3D print one. I have my EPP-400 already so I can test fitment and fans.

Hello. With the recent announcement of G-Unqiue’s entry into the PICO Plug-in Type (which I will now refer to as Plug-in DC Board or PDCB for short), I have decided to revamp this thread into a general guide to Meanwell PSU. As I learn more and build into it, I will add information and update...
