and it works fine ,it 's a continuous run!!!

That's good news. Thanks for the follow-up.

@Mellon Head - only 25 years? Well, don't worry, I won't hold your youth or lack of experience against you! I am sorry you felt it necessary to take this attitude and edited out your post, however. If there is one thing I have learned in nearly 40 years fixing hardware, there is always more to learn. I've been wrong before, and I will be wrong again. I don't like it so I try to ensure I am not before I post. But if proven wrong, I see no reason for the sour grapes attitude.

And don't lecture me about current capacity, and composition, etc. I did look up some specs before doing the math

You went to great lengths trying to disprove a point you took out of context by discussing Ohm's Law in detail, tossing out figures of 6000°!!!! :sarc: I mean come on! 6000°? The melting point of copper is only 1083.0 °C (1356.15 K, 1981.4 °F). But as noted, even if you did "look up some specs" - you did not and still do not know the wire gauge and therefore you did not know the current capacity. Therefore, your facts were inaccurate. If you did do the math, you made assumptions you can't, then expected us to accept them because you said so.

So don't counter others, or lecture us on electronics then not expect your facts to be checked, then have a cow when your facts are shown to be flawed. Either stand your ground and support your position with substantiating facts, as I did with the ATX standard, or gracefully admit the error. If admitting mistakes with grace is not something you can do, just let it slide. Going back and editing out old posts (adding colorful commentary in the process ) helps no one learn anything and learning is what this forum is all about.

I'm only here to help the posters. It is obvious you are a student of electronics and that is refreshing when often we see folks calling themselves "technicians" when their only qualifications are they "assembled" a computer - which takes what? One #2 Phillips screwdriver.
