I converted an old 300W computer PSU into a DC Lab Power supply. It is a cheap alternitive to buying an expensive lab power supply. My Converted ATX Psu can give me 3.3,5,7,10,12,17,24 volts. It is a very Useful thing to have around.

  • you can replace the ...

    you can replace the diode on the -12v rail with a larger diode to get more ampers out also if you put a nc button from the input voltage of the pwm to the safety resistor you can press that to reset the OCP
    i did alot of experimentation on push i was able to pus 50v out of one by modifying resistors

    it works ok. there is heaps of noise on the outputs tho so its no good for running anything to do with audio. and instead of hooking all them wires together you can just cut then off and use one of each colour.
