Well, I was working on my friends PC last night, it had been freezing a lot and I narrowed it down to the motherboard, so I backed up all of his data and reinstalled everything on my old motherboard for him. I had two of the same motherboard, the case I installed XP in was just much easier to work with. Anyway, I finished the installation, moved all of his data back onto his hard drive, put all of his stuff in my case with my motherboard, video card, ram, dvd-rom, modem, floppy etc.
Then I started to plug stuff in, keyboard, monitor etc. when I plugged the power cable into the PSU it immediately started itself and then died with a definite smoke smell. I killed the power on the back. Opened the case up and determined that the smell was coming only from inside the PSU.
What I was wondering is if somehow my not turning the power off on the PSU before I plugged it back in is what fried it? I don't think I ever really paid that much attention to whether the PSU is on or off when it's unplugged. I know that I've left PSUs on many times and have never had a PSU start up by itself after plugging it in until now.
Is this something that is known to happen? Is it considered bad to leave the PSU on when not plugged in? I guess I always just figured that if there's no power feeding it it doesn't really matter. So is this something that was caused by that or is it just an example of a cheap PSU dying on its own?
