Case lighting?? Oh wait, computer is on FIRE!

So I went upstairs to get a snack and, upon my return, my case is emitting a weird orange glow. Peering through the wire mesh that makes up the top of my case, I can see a small fire centred on the DVD-Burner's molex cable; necessitated by the case's height.

The computer was still running as the cable burned, with no apparent issue. Nor could it have been a power spike as I use a UPS. I even had to turn the computer back on (w. all HDDs disconnected) in order to update the wifi password on my laptop (to post here) and it booted just fine. Nevertheless it's currently shut off.

Was this just a faulty cable (or DVD burner) and not a bad power supply*? Googling led me to this conclusion, but I wanted another opinion... or two. Thanks.

Bad connection(either contacts or damaged wire in the molded plug during manufacturing) -> increased resistance -> increased heat -> melt/fire
Recycle the burner and that cheap adapter. The rest of your PC is 99.5% fine once soot and such is cleaned out and anything above the fire is inspected.

I don't think Ill even get a DVD rom next time. I dont burn anything. And I can DL a game a lot faster then installing from disk.

I have never heard of that happening. Your lucky it wasn't worse. Are you able to pull the connector to see if it was a fire from inside the burner, or just the connector?

Wow good thing it was that small of an accident.

Probably like a defective molex to sata power adapter or dvd ROM sata power plug.

The burner (which wasn't in use at the time) was just shy of five years old, no idea if the cable is even older. The cable can be pulled and, based on the level of destruction, I'd guess the fire started in the molex cable. Roughly half the sata power plug remains intact, while the cable is mostly carbon now and melted elsewhere on the affected end.

Played an hour of Team Fortress 2 with no issue, so....

Maybe a short on one of connectors within the molex. Glad to hear there doesn't seem to be any other issues.

Never seen anything like it. Good thing you noticed something was burning inside the case!
