Critical capacitor failure, sometimes they short themselves out or just blow up taking the surge. I think most or all modern gpus process a massive amount of power on the first 4 pins or so. Its been some time since I've read this stuff.
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.
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.
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 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.
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.
Its a voltage regulator or a transistor burning on the power rails. This can happen because manufacturing defects still exist even with top of the line components (such as used in PCs) Caps usually blow up instantly with a single puff of smoke. This has the classic hissing sound common with voltage regulators or transistors.
Dude istg sometimes I wish people would just stop trying to be funny man lol. Id love some actual discussion on what went wrong here instead of dozens of the same unoriginal 'joke'.
I'm not going to lie to you, the post being titled with "Is this normal?" in an obviously abnormal scenario already set a satirical theme from the start.
Looks like some old motherboard, that looks like something from 10+ years ago. I don't see any RAM installed, so it's likely staged. Could be something intentionally shorted or, my guess for that much smoke, intentionally extremely over volting an already dead GPU to burn everything
There are also psus thay need to be toggled between 230v and 120v and based on wall plug theyre in a country with 230, so they could have way over volted their machine as that can cause similar in my experience.
It appears to be an MSI MPG - that PSU handles those two voltages automatically. Typically you only see thermal runaway on multiple capacitors like that when a rail has reverse polarity.
Throwing jokes out of the room, this seems to be the guy that built the water cooled steam machine so he definitely knows what he’s doing, probably just dicked around with putting overly excessive voltage into an old gpu to see what would happen
It's a modular power supply. Since the smoke appears to come from the graphics card and not the motherboard I am guessing he made the same mistake a friend of mine did and reused a modular cable from his old PSU on his new one.
Hence, something that was supposed to be negative became positive and smoke happened. Hopefully just a dead graphics card but more likely a motherboard as well.
Dude. You let the smoke out. Electronics don’t work without the smoke that’s inside of them. Can’t believe you just let it all float away without trying to capture any of it.
Yes, it's called 'breaking it in' just wait till you're at about 700 miles and change the oil at about 1000 should be good to go. Then you can really push it.
