Question 2 Dead GPU's from power modules literally exploding...

[MachoTaco24]

Hi,

I've had two identical EVGA GTX 1070's FTW over the past two years. My first one I've had for a few years, put a lot of mileage on it. One day playing light games, it quite literally combusted around a year and a half ago. Luckily I was able to get an identical card from a friend that he no longer uses, and just recently now I turn my computer and the thing goes ablaze. The first 1070 had damage near the power connector, while it looks like for this most recent incident, one of the capacitors blew up. Aside from replacing the GPU, I've kept the same setup since this started happening: https://pcpartpicker.com/list/W63HLP. My power supply is an EVGA SuperNOVA 850 G3 850 W. I made a post here about my first 1070 that broke as well, you can see it here: https://forums.tomshardware.com/threads/gtx-1070-spontaneously-catches-fire.3716686/#post-22407465

What should I do? Is this just a freak accident that occurred between two identical cards? I already have a replacement 1060 from a friend, but I don't want to put that card in if it's just going to explode again. I'll be honest, I don't dust my PC as much as I probably should, but there was no indication that this should've happened. Should I check my power supply? From what I can tell, this issue is largely power related between the two cards that got destroyed. I feel like since these two events were over a year apart, I should be okay to put the new card in, but I'd like to get some feedback to make sure.

Thank You!

Its a common problem on FTW 1070s from EVGA, just a bad model, just get a different model/brand and it should be good to go.

You have a super nice system compared to your GPUs.

That said, If the above is true, I am not familiar with it, then that is most likely the answer. Otherwise, I would definitely question the PSU. While you have a good PSU, they can still go bad sometimes. Due to both your cards being identical though, it is quite possible that it is a model fault. If the two GPUs that died were entirely unrelated, then I would go straight for the PSU, but since that was not the case, you should probably be fine to use the 1060.

That also said, I dont like that the first card had scorch marks at the PSU connectors. Make sure to inspect, and potentially replace, the PSU cables if they appear to have damage to them. The PSU itself could be fine in this instance, but the cables themselves are compromised.

my friend bought the same model 1070 and 8 months later it exploded due to the same problem, of course thats not enough definable evidence but this is the second time ive seen it and i dont see many 1070s.

And why did you not replace the power supply after the gpu blew up?????
