ATX Supply

How to convert a standard ATX powersupply to a lab powersupply?

In need for a powersupply that can really give some power I converted a standard ATX powersupply from an old desktop PC to a Lab Power Supply of 350W.  With 40A at 5V and 15A at 12V I sure have some power to play with. Maybe I now can finally start working on a robotics project with some strong motors that need some amps to run… Well, if you are interested in a how-to-convert-an-atx-supply, you should continue reading….


Let’s start with “Why would you do that?”
Well, I am always playinh with technology and electronic parts and most of the time I take an old adapter for a supply but those are always limited to 500mA or 1A max. So sometimes when I need more amps, I used to put paperclips in a connector from an old ATX powersupply and shortcut the poweron signal. The great thing about ATX power supplies is that they can give a lott of Amps, have different voltages, are very stable and have build in protection. So almost ideal for benchtesting when you dont want to buy a real lab supply. If you are still reading, you probably know what I mean.
