By good I mean it won't kill the motherboard it's connected to if something goes wrong with the PSU (over heat, end of life, short circuit, too much power used)
Let's say I have some power supply (no name or some strange one I've never heard of), can I tell if it's good quality by looking at the components inside?
The reason I won't just pick a well known brand is because I need -5V (which many new PSUs lack) (ISA bus uses it. I am building old computers like socket 7, socket 462, for fun).
I don't care if the PSU itself dies early or is inefficient, I just want to know that it will protect what it's connected to if something bad happens.
I have heard of some power supplies that killed the motherboard when they died.
