I was trying my old Eagle 320w PSU with the system in my sig, plus 3 fans DVD-R/RW and CD-R/RW.
Within 3 hours it blew up. I had the side of my case open at the time, when all of a sudden I just heard something, like a strike of a match. Before I knew it, the PSU was on fire, it lasted for about 10 seconds, and the smell is still lingering.
Funny thing is, I’m still using it, I’m using it right now as I’m typing this message, and seems to be working well, but for how long, I don’t know.
