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.

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.
