Blown PSU??
My 500w PSU has blown on another PC i have and was wondering what the
chances are of other hardware being damaged as a result. My spare PSU has a 24pin mobo connector whereas the blown one has a 20pin so i will need to get one from my local store if they have one and try it. Thanks. |

My 24 pin supply here, the connector comes apart in two pieces, so it is 20+4. You unhinge the extra four, and then the connector becomes a 20 pin. There are a few connectors which are purely 24, and for those, you cannot convert them. But if there is clearance around the connectors, and no tall capacitors in the way, you might still manage to connect it. Pin 1 on the 24 pin, goes to pin 1 on the 20 pin. You can see a picture of a 20+4, in the upper left here. http://lib.store.yahoo.net/lib/cputo...e/mp3atx40.jpg In this picture, you can see the "bump" for the hinge. http://www.pcmcis.com/Pro/204pin.jpg In this shot, a fixed 24 pin supply, is plugged into a 20 pin motherboard. The four redundant pins, hang over one end. On some motherboards, a tall cap is located, where the four redundant pins are, and then you cannot do this. But if the area on that end is clear, as it is in this case, you can do it like this. The alignment feature of the connector, should help you as well (if you fit it wrong, the shapes on the plastic shell should prevent it). http://www.playtool.com/pages/psuconnectors/24in20.jpg Many current power supplies, can blow without damaging the motherboard. There were some in the past, which were notorious for ruining the motherboard (Bestec 250W). But if the supply has a half decent set of protection features, it might not have hurt anything. Only time will tell. If you paid $15 for the supply, the outcome is less certain. And in the event of a lightning strike, the power supply may not get to say much about it, and it could be fried anyway. Paul |

I have had about four or five go without problem. My friend had a cheap
power supply and when it when it took out everything but the hard drive. Buy a nice name brand PS that will have over voltage protection. |

Usually, a failed power supply will not damage any other components.
There are exceptions, but the odds are in your favor. timelord wrote: My 500w PSU has blown on another PC i have and was wondering what the chances are of other hardware being damaged as a result.
