PSU revisions

Hi @intellijellies,

I noticed on SchneidersLaden that the latest 80W PSU is in revision 7 now and says low-impedance on it. I tried to find a changelog between revisions but couldn’t. Are there any performance differences between them? My 7u case is an earlier version (not sure of the exact revision but it’s green), and I was wondering if it would be worthwhile to upgrade it to a newer one.
