I found many pages where people convert an ATX power supply to a benchtop power supply to give 12, 5, 3.3V.
However the current output can be very high (several amps).
When using this and you NEED high current, that is great. However, when using this for typical benchtop hobbyist needs (e.g. supply 5V to a microcontroller) the current supply needs are small. I understand that it will draw as much current as it needs -- but my question is one of safety. Since the current "compliance" is essentially set to several amps, what happens if I accidentally touch + and -? Or what about if something in my circuit suddenly blows up and shorts + to -? Then I suddenly have several amps running thru my circuit. I believe then an internal fuse in the ATX unit will probably blow (right?) but at least for some short length of time there were several amps running thru my resistor right? or Wrong?Would anybody have a simple adjustable current limit circuit that I could build and add to my PSU?
