| Help getting a Dell power supply powered up |
| (1/3) > >> |

I have a Dell PS-5231-1 230W power supply and am trying to figure out how to get it powered up. It has a 20 pin connector that goes to the motherboard and I need to figure out (I assume) which pins to jump to simulate a switch to get it started. If any one knows how to jump start it or where to find the wiring schematic for powersupplys would be much appreciated. It was in working condition when it was given to me and I have found 2 of the 20 pins on the connector are showing 12V but there is no voltage anywhere else nor is the fan running. ??? |

If its an ATX power supply, short the green/black wires in the middle of the connector. There is only one green and there's a ground next to it. |

Thanks. I'll see if it is an ATX and try it out :D |

That may, or may not, work. If the motherboard doesn't like that the POWER_GOOD variable is flakey, it may not power up. I started a thread not long ago regarding just this (and it's a topic that comes up a lot) Take a capacitor, 10v 10uf, put the legs into a jumper (after removing the strip of metal, that is) and put that assembly onto the power switch pins on the motherboard. |

Unfortunately the 20 pin plug has every other color in the rainbow but no green wire. I plan on using this to test lighting, LED's and what ever else and possibly using it as a standalone power supply for my next cabinet. There are 2 pins off the mobo connector that are showing 12V and several black wires on the it as well. I'm assuming that jumpering one of the 12V pins to one of the black ground wires may start it but then again I may be looking at nice fireworks show. I'll try checking again on previous postings on this. |
