| 説明 | (part 1)... and here is what I found.The fried wire was burnt across its entire length. But the end inside the power supply was not connected to anything. It's just a neatly tinned wire that somebody forgot to solder in place. That's some fantastic quality assurance.Anyhow, I suppose when I did the memory upgrade, either by tipping the machine on its side or moving the power wires out of the way of the RAM sockets, I somehow cajoled that free wire close to that ground jumper (just to the right in this photo). The burnt wire is one of two wires connecting to one socket on the motherboard (which is why the PSU worked for two years; the other wire was bearing the load). But in this case, +3.3V went through the other wire to the motherboard socket, and then back through the free wire to ground.As to why only one wire got hot enough to bake the insulation off it... either it's somehow a smaller gauge than the other (hard to tell now ;) or possibly several orange wires shared the outgoing load, with only the free one carrying the return load. (I'd think this would have burned traces on the motherboard, though, and I couldn't find any, and the motherboard has been running fine with a different PSU for weeks.)The moral of the story? Stick with name-brand power supplies from now on... it costs a few more bucks to buy the PSU separate from the case, but a name brand unit is less likely to fry your computer or burn your house down... |
