Sparks and smoke on my EVGA X58 SLI 3-way. What next?

post #1 of 4
Thread Starter 
Hello! I've had this EVGA X58 SLI 3-way (132-BL-E758-A1) in operation for about 3 years now. I completely took it apart and stole some parts for another build. After rebuilding this machine I powered on and noticed that dreaded burning electronics smell. I quickly powered down and opened the case. I was unable to locate any visual signs of damage so I powered on again, saw sparks and smoke, then quickly unplugged. Sparks and smoke seemed to be coming from the JSYS1_FAN header which had a 120mm exhaust fan plugged in. I removed that fan assuming it had a short and powered up once more. Still had sparks and smoke in that same area.



At this point I was more than worried about damage. I removed RAM and graphics, reseated ATX 6 pin and 24 pin power, and left the system sitting for a few hours. When I came back I powered on again and both the blue and amber LEDs on the board lit but there was no fan movement. I reseated RAM and tried again, still no fan movement but both lights were on. I let it sit for another hour. When I came back the final time and powered on I had sparks and smoke near the JPWR_FAN header, but closer to what I believe is an inductor right by the fan header. I also had some blackened char under the screw when I removed it.



At this point I'm not sure what's wrong. I'm guessing: A) The PSU is bad. B) The motherboard is shorting with the case. C) The motherboard got damaged during removal/reinstall and has power problems.

My next step was going to be pulling the components out of the case and attempting power on with a different PSU. Can I damage a different PSU if something is wrong with the motherboard? Is there a test I can do on the PSU to remove it from the potential problems list?

Any thoughts on how to proceed would be greatly appreciated.

Well the motherboard is shorting out on the case for sure. Maybe a bare cable somewhere in the rest of your case is touching the case?

I don't think so, but it's possible. If I take the motherboard out and set it up on the desk do you think it's ok to continue testing with the same PSU?

If you have burnt traces under a screw the mb is toast. I would not bother testing the board at this point as you can and probably will damage components.
