So my psu died (didn't explode but it popped)

[ᛊᛩᚴᛚᚢጊᛉ]

While waiting for the company to send me a new one i started overthinking like hell, seconds before popping my pc shut down and the second after my psu made a semi-loud pop and after that it didn't make any sign it was alive, my friend tested my pc with his psu, and everything worked just fine, made stress tests, and it was all good, was i really that lucky that nothing else burned with my psu? Maybe it wasn't that of a strong pop and it didn't affect anything else? Does someone have any experience with these kinds of situations? My psu is NZXT C 850 W Gold, not a bad psu at all, but it died on me, and now i am panicking it will ruin my pc (long term or short term) that has strong components in, like the new 9800x3d and rtx 4070 super for example(not bragging)
If someone knows a bit about my psu, some feedback about this situation could be very useful and a relief..

Also, this is the third day i was using it so we can say that the psu is new( or at least was)

That is a very bad sign. Don't try to use the PSU at all. Replace it ASAP. Inspect the motherboard closely before trying to start it again.

And use a good surge protector. They're as much for stabilizing ordinary dirty power from the grid as they are protecting against surges.

And, needless to say, try to keep them unobstructed and free of dust, especially if the PSU is downward-facing. Get a caddy or cradle to hold your case up off the floor, and dust it out annually at least.

4070 Super is not very high power consumption, only 220W TDP card. Guess the PSU was just faulty and luckily safety systems worked.

I didnt' use it at all after that, it wouldn't even start, the motherboard was fine, no burning smell as well, my pc is still at my friends where he tested my pc after that incident with my psu with his psu and it worked the same, the thing is i am sceptic because i know everything is fused together and because of that i suspect something can be damaged even if the stress tests showed nothing

[ᛊᛩᚴᛚᚢጊᛉ]

Rumpelcrutchskin,

Let's hope it's only that, all my components are new as my psu, i do have warranties for them all, but still that is a long process to swap them with new ones if something went bad after the psu incident.

Psu did its job well actually by self sacrificing before allowindamage to mb.

They do that? I'm not well informed into these things so could you tell me more about it?

Had it happen to me before, but nothing was damaged. Well it happened twice, and nothing was damaged.

However that was back in 2012. Post-pandemic, I don't know the quality of motherboards and components anymore...

so the psu does not send voltages out of spec to the board gpu, drives or anything else attached to it

many poor/cheap psus with improperly set protections will keep trying to power everything, while spiking voltage higher than the atx spec which can kill mobo, gpu, drives or ram

quality psu is generally overlooked, since it does not impact system performance at all, but it does guarantee system safety if anything goes wrong

generally the price diff between a junk and good psu is around $20

Good feedback, thanks, my psu is considered in the A class of psu's, the thing is it seems it was faulty sent to me, 1 of 100, i mean NZXT C850W Gold ain't a joke of a psu imo

Maybe I’m looking at the wrong PSU, but it looks like Tom’s hardware gave it a 3.5 out of 5, so I would have kept looking. There’s a few DOA so the caution flag is waving. Now that yours died I don’t know if I would trust it or keep it when I rebuilt down the road, becoming a throw away.

I’ll pay more for quality and over kill when it comes to the PSU and case. My case and 1350w PSU is over 12 years old. I had Sli at the time, but I definitely like more then enough. A 1500w PSU looks like a better match for your system. Yeah, maybe over kill, but I would start there vs starting with the minimum. Just like I do everything else. I’ll start off wanting Sli 5090s at first and then save money by only getting one instead. Lol Naa, not to play 10 yr old games.

I see again (some) people spread nonsense about power supplies.

The only thing that (kind of) sacrifies itself for protection is fuse. Fuse can be destroyed by overcurrent and that is good. Anything else that has broken in the PSU is a sign of poor quality. (broken fuse can be easily replaced by somebody with basic knowledge of electronics and PSU should still work).

Over 1000W for system with Ryzen 9800X3D and RTX 4070 is a big overkill (read waste of money which could have been spent on GPU, for example).

I have a simple rule for the quality of PSU, looking into years of warranty. The companies know the quality of elements in the PSU and they adjust warranty accordingly. It works in the EU (in some countries it might not work, if giving the warranty but not respoecting it, is cheap).

I know that most people like modular PSU, but it does not make much sense. Good quality connectors actually cost money. There is about 20EUR price difference between same non- and modular PSU. Funny thing is most cables will be connected anyway, so you only end up with more connectors. (Hint: if you want to spare moeny choose good quality non modular PSU)
