Audible (not loud) pop sound then smell of burning after installing new GPU

[Deado]

Title.

So recently I bought a brand new 4070Ti (Gaming X Trio) and new case to fit it inside of for a PC upgrade, but after 8 hours of labour and wiring everything up, I plugged everything in, pressed the power button, and after a moment there was a very quiet pop sound (which I thought was just the AIO Cooler), but after a louder (still not loud) pop, I could smell a distinct burning smell which filled my entire room after a few minutes. I turned my PC off after a couple seconds as it didn't power itself off.

 

I haven't done a sniff test to see what smells bad yet, instead I just went to bed and figured I'd deal with it tomorrow, which is now today.

 

Specs: RM750x, 4070Ti Gaming X Trio, Ryzen 7 5800X, 32Gb Corsair Vengence (3200), Asus TUF X-570 Gaming PLUS (Wi-Fi).

 

I did use only one PCiE Type 4 cable plugged into the 2 connectors for the 16>12 pin converter, but I read online that this was fine to do since both can handle 150W/ea. Now the question is what do I do next? I have a 2060 but don't want to fry it or anything else w the PSU if it did sacrifice itself. Should I get an RM850x so I can have 2 dedicated cables to the GPU? Could the GPU be the problem and, if so, kill my new PSU if I do get one?

I'm stressing so hard over this so any and all advice is greatly appreciated...

Thank you all

oh no thats not very good. i would try and smell where it is coming from. best case senario your gpu is dead and you send it back. worst case somthing ese could be dead.

Not good at all the smell of DEATH. Feel for you, I'd hope it was PSU what has FRIED as cheaper to replace. I would not power it on again until you can test all PARTS with other hardware. If it's the PSU then it's not tooo bad, a lot cheaper than replacing GPU. Most likely PSU but could be MOBO or GPU what has FREID.

Pop + smell = blown capacitor.

Yeah, I'll have a sniff around when I get back home in a couple hours and will update then - if the GPU is dead then I can probably replace it since it's brand new, but if it's the PSU then I'll have to replace/upgrade it out of pocket til I can figure something out w Corsair's support.

Yeah this was my thought once I'd calmed down a little, only thing is that almost everyone online has said that capacitors going are rather loud (like someone clapping their hands) when for me it was audible but not loud...

191x7 is right. pop sound with a smell is a capacitor dying. If you're unexperienced with opening hardware and don't want to do so, I would recommend taking it somewhere instead of testing on other hardware and potentially frying anything else

Iv had fizz, pop, crackles before on gpu that have fired a component, along with visble sparks or just a puff of smoke..always smells

 

I would pretty much lean towards the gpu as that was the new component to the system, could be psu or anything, but probably gpu, i'd also check your pcie socket is intact

[Deado]

SO, after a decent amount of sniffing around, looking for popped capacitors and scorch marks, making sure the PCIe socket looked fine (ty for suggesting that aledsav1), etc., I figured I'd just go for it and pull the GPU out to see if the system does the same thing without it in. Took it into the kitchen where fires are less problematic, just to prepare for the worst, and when I powered it on - it worked fine. Tried with my GPU to see if it'd do the same thing... still absolutely fine, powered on perfectly.
Now when I took it upstairs and booted into Windows, I noticed that my front 6 fans were running at full tilt, so I looked in iCUE and none of them were there, so I had no control over the RGB either. What I'm thinking is that one or both of the hubs that came with the new case (which I didn't even consider to possibly cause issues) shorted, which would explain why the pop wasn't loud at all and I never saw any smoke. 

I've run a couple stress-tests & benchmarks since then, just to make sure everything is hunky-dory and I'm just gonna say that I think that ~600FPS average in FurMark seems to show that it's alright!
I plugged my fans back into the old RGB Hub and Commander Pro I had from before, and all 6 fans are working well (besides the RGB being confused and showing weirdly - as when I put RGB on one fan it'll also try to put that on the inside of another fan, but I'm sure that's its own problem or I'm too dum to use iCUE lmao). Played NFS Heat for a good while at max settings and my GPU was sitting pretty at 55-60C max (pretty sure my CPU is the bottleneck since it's running at 95-98% load at around 75-80C the entire time, but that seems about normal for NFS Heat) with lovely smooth performance.

Thanks everyone for actually helping my mind think more logically about things!
If it explodes on me in future I'll make sure to let y'all know lmao

 

Pic for reference (don't mind the atrocious cable situation at the bottom, that was just since I cba to plug back in or move cables out the way haha, it won't be like that forever dw)
