That's really cool jens.
One of the main attractions for me was the fact that it'd have 12/5v out of the box, but if that's not reliable then I guess it's not much of a benefit. I was trying to avoid doing as much as I could myself, I know power can get pretty difficult and I'm somewhat of a beginner here.
Also a bit worried about the fact that I can't limit amperage, most of my devices are very low amperage, just a couple are a bit higher.
I'll run some tests on mine when it comes in, it's not a dirt cheap one but not the most expensive either.
Luckily a small ITX motherboard has become part of my project, so even if I can't use the PSU for everything else I need it anyway, so nothing wasted.
Thanks for the feedback!
