Is my CPU broken?

Hey guys, 

I think I broke my CPU but as I have no way of testing it in a different board right now I just want to know what my chances are. 

 

Here is what happened: 

 

I connected a Sonoff Basic (I know..) in parallel to the power button, plugged the Sonoff and PC in and instantly blew the fuse. Also it smelled funny.

 

Soo yeah I tried to turn the PC on with 230 Volts AC. The board is dead. 

 

Is there a chance that the chip was saved? 

 

The burn marks are only visible around the IO pins.

 

The board is an Asrock h87 pro4m and the CPU is an Intel Xeon E3 1230v3.

 

Any information on the probable health of the CPU and maybe even GPU is appreciated. :)

no way of telling. CPUs dont die with sparks or smoke.

Is it possible that the voltage/current didn't even reach the CPU?

sounds like there's an okay-ish chance the board took most of the hit, as far as i'm aware that signal has quite the way to go before it reaches the CPU.

 

start with giving your ram sticks a sniff test, if they all pass i'd give the cpu a decent chance.

As far as I can see this is the only visible damage. RAM and GPU smell fine.

Lord Jesus it looks like you've fried everything in that corner.
Did you actually power the Sonoff from the mains directly into the motherboard's header?

It's not a race to the bottom.
