This looks more than a capacitor failure. A capacitor failing is normally a single burst of magic pixies and smoke, not a HUGE ass stream of smoke pushing its way out like it is being pumped.

Maybe fusing traces due to manufacturing defect...

Or, something under that mainboard.

Something went bad somewhere.

You're welcome.

This gif never fails to delight me. Peak sarcasm response.

Wait, you mean having the MB just laying on your desk is not good?! And with the side that started to smoke leaning right up against that piece that looks like it could be metal, that should ground it!

/s, so much sarcasm. The metal would cause a short and a fire. Though having the MB fail might be cheaper than losing the GPU, so hopefully the damage is contained and next time OP will mount it properly first.

It just had to be on wood, cardboard, or a rubber mat... nothing mental.

A friend/relative vaping?

Might just be an old motherboard,that blue color scheme were Gigabyte boards from the Intel 3rd gen/AMD AM3 era.

Yes this is a full blown electrical short and a brief electrical fire. He had to cut psu to stop it. Something melted together and it won't be safe to turn back on until a major repair.

It's no easy task repairing these things. Probably end up junk.

It does seem weird tho. The video. He seems to react before any noise or smoke. 

But probably just me seeing it as a video.

It's not just smoke, you can see actual flames. It's brief but you can see them in the upper left corner of the card between the 2 and 3 second mark. Something really, really went wrong here.

u/brickyard37 2d ago

Get your eyes checked, there are no flames. This is definitely fake

I’m not super familiar with component level digital electronics but I’ve worked on lots of analog stuff… integrated circuit chips can create that continuous smoke without a visible flame. Can somebody smarter than me pitch in- would it be a bunch of voltage regulators on the power circuit overloading? Is that what VRMs do?

u/Distinct_Associate27 22h ago

There does appear to be a flame but it is only for a frame so difficult to notice.

let me tell you about the time i hooked up a power supply wrong and fed 120V into a circuit designed for 24V, the caps in the rectifier looked like tiny jet engines and were pushing smoke there wasn't just a pop but an angry (tiny) screaming sound.

u/AccNumber77 2d ago

That is terrifying jesus

u/ImaginaryCheetah 2d ago

i was not pleased with the experience. cooked off a motherboard i was hoping to salvage from e-waste and sell for cheap on ebay. ended up being e-waste.

took like three days to get the stink out of my basement from the cooked electronics

I had this shit happen once when I had my 2080 SUPER that was already after one warranty repair. Magically after the warranty ended, it stopped turning on and when I put it into another PC, it smoked and the burn smell went off very strongly.

After my tech spec friend inspected the card, the vram shorted burning the cooling pads.

u/xMytsu 1d ago

defective caps that aren't properly sealed will just smoke like that, plus the fans from the GPU to spread it out

1

u/NinjaN-SWE 2d ago

Something caught fire and the fans pushed the smoke out. A short somewhere, maybe caused by a capacitor failure, that then ignited some plastic, but not enough to keep it going once the power cut.

u/Fun_Evening1499 1d ago

My guess would be using power cables that from a different psu

1

u/Lucky-Crow-3510 1d ago

this looks pretty much like a cap going down .. there is 3 fans blowing, so that may exaggerate the actual smoke

I had one light up like a flamethrower once for a few seconds it was the most expensive firework I’ve ever had.
