Well I could probably live with just varying the voltage so long as I can still get a decent (like 10A) out of it at 12V. I would be very appreciative if you can explain what I need to and what components I will need.

Yes, I understand that. But I want to control the voltage and/or current like a benchtop power supply does. It would even be nice to put an ammeter on it so I can see what's doin'.

Hi folks, I read through the article below describing how to make a lab power supply from an PC ATX power supply. The link is here: http://www.wikihow.com/Convert-a-Computer-ATX-Power-Supply-to-a-Lab-Power-Supply I would like to make this a variable power supply that can generate the full rated amperage. I will need about 12V and up to 10A on the 12 V setting and up to 25A on the 5V setting. I am extremely electronically challenged so please be as explicit as possible using laymans terms. Thanks.
