You are both right. It is easy to get caught in the "As many amperes as possible" thing...
However, here's my situation: I am a hobbyist with limited space. In fact, my workbench is my desk which resides in my living room...
So I need one (a dual in this case) PSU to cover all my needs.
My needs now, are mainly powering electronics homebrew projects for which 1 amp is more than adequate.
Once in a while though, I need to power some electromagnet and this is where the amperes really makes a difference.
Now like I said, my desk/workbench is pretty packed as it is, so what I awant to do is replacing my current 2 amps psu with this one.
Thanks for your time.
