I'm not sure whether you're looking at a bad power supply or a bad processor, or something else. Could you go into more detail about how the plug shorted out? Is there any physical damage to the power supply? Before you go on replacing parts, you should consider what may have been damaged and how much it would cost to replace them all. You may find that it would be cheaper to buy a full working system, use its parts to test your own, and sell whatever you can verify works. A Digital Audio system is pretty cheap these days, you might even find it feasible to pick up something newer. I see Dual 1Ghz Quicksilvers sell on ebay for under $200 shipped pretty often. It is possible that the power supply had a surge of power which ran through the low voltage lines causing the capacitor to blow. It is also possible that this surge was 120v AC, in which case it may have been enough power to damage the CPU, video card, RAM, ect, depending on which line(s) it traveled through and how far it got before being stopped. If just one other damaged device is connected it could be holding up the power on self test. Since your power supply does seem to power on, it may not be faulty. If you have a voltmeter or are willing to pick up a cheap one, you could check the voltages to see if all are being provided. It is possible that just one voltage line is damaged. Anyway, I run the ATXG4 website mentioned at the bottom of Kris's link. If you were to buy an adapter and it doesn't help in your situation, you can contact me to return it. I'll only charge you for shipping. I would like to note though, the power supplies offered by Computer Geeks are... crap. If you chose to go with one of them, you should expect problems with putting your system to sleep. My favorite power supply for use in G4s is the Thermaltake TR2 430w which can be found for as low as $20 shipped (after rebate). -Donald Hall http://atxg4.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
