Please who have an odea about the power supply of the PC, i know that the power supply of the PC can output 5 and 12 V, what is the maximum current ?
can i design a power supply of (12V, 6A) from the PC ? can i use a potentiometre to make the current output changing from 0 to 6A ?
 

PC PSUs come in different powers, Google for "AT PSU", Here is one I found earlier :- **broken link removed**
You don't need a potentiometer to change the current, the voltage stays the same (+12V) and the current drawn is dependent on the load.

Yes but i need to limit the current, but i don't know how ?
 

A PC power supply has some kind of overcurrent protection, but no exact current limiting. And surely it's not adjustable.
 

i need to output from this 12V, another supply 12V but i need to limit the current, how can i do this ?
