Converting a PC PSU to a 12V DC bench top power supply.


Today, I converted a Hewlett Packard 500W PSU to a 12V DC bench top power supply to use with RC battery chargers. I cut off 53 wires and 10 connectors. I grouped like wires together and then covered them with heat shrink tubing. I soldered 6 12V leads and 6 ground leads each in parallel. I soldered the power on signal wires together so that the power supply turns on when plugged into 120V AC. When I was finished I connected my Turnigy quad charger to the converted PSU and the charger lit up and then I charged a 2200 3S LiPo at 8.36 amps. Pretty cool.

@Kmot :

If I remeber right , there is a single purple wire in this PSU that is the ENABLE for the whole output . Can't recall if it has to be grounded or connected to +5 to activate .

Yes, there is a single purple wire in the 24 pin connector. None of the videos I watched on Youtube referenced that wire so I did not do anything with it. But thanks for the heads up.
