Stefan:

Thanks for this info.  I have been looking for a cheap but decent power supply and did not realize I already have like three of them.  I'll bet the power is pretty clean too as evidenced by their intended use on computers.  For a little money, there are larger supplys available from newer computers.  Thanks again for posting this.

Hi Harti_Berlin (Stefan)

Thanks you very much for this link and also  for pointing out www.wikihow.com

Will the next wiki be wiki_OU.com? :)

I usually destroyed all the computer power supplies that came to my eyes for  collecting some parts. :-\
Now, I will be more wise.

Best

The features of a LAB power supply are perfect galvanic isolation, rocksolid load regulation/stabilization, the ability to source/sink current, .... immune to rf interference.
Thats the reason why they are expensive.
A converted PC power supply is missing all these features.

If you just need regulated power supply - well thats a good option.
