team,

I had the following issue . I was playing a game when suddenly the computer restarts. It starts to run the standard repair processes when I see back smoke coming out of the back of the computer and that funny burnt smell. I disconnected the power immediately and removed the video cards. Tried to turned it back for a second and black smoke again.

I initially thought that the power supply went bad and it's already on the way to seasonic RMA but later, I brought my seasonic x-650 from work and tried to replace all the connectors to make sure nothing else was damaged.

After connecting everything, computer won't start. Not even a light in the motherboard. Doing some basic troubleshooting I realize the after disconnecting the power of the H220 pump, computer comes back up. I remove the heatsink/pump and inspect it closely.

I realize that burnt smells comes from the joint of the wire and the pump enclosure plus a little of burnt wire there too.
 
Sounds like something shorted in there. I would test whatever header you had that on as well but sounds like just the cooler.
 
Do you have a spare CPU cooler of some kind to temporarily cool the processor so that you can confirm the rest of the system wasn't damaged by the pump failure?
