Kaboom!

So my PSU exploded last night on my desktop. Seems the little ring inside, you know the one encircled with copper wiring that I guess acts as some form of electromagnet, yeah well it ummm fell off.
Sigh. I mean seriously, wtf. I only got that PSU in October. It wasn't that bad, 450w, 25 amps on the 12v rail. It suited my needs. :(
Anyway. I'm making a trip to a few computer shops in my local area today to see what I can pick up but in the meantime I'm on laptop until I find out just how much damage was done to the machine. hopefully it didn't fry the new mobo because those things are seriously difficult to get hold of. If it did fry the mobo and/or the GPU and/or the CPU then I think I might just bite the bullet and build a whole new PC. We have a spare comp I can use to retrieve most of the data so I could go SATA I suppose. But that will be both time consuming and expensive so fingers crossed that it's only the PSU that's knackered hmm?
