Dead PSU or GPU?

[Jonas Rudlang]

Not sure where to post this, feel free to move if it's in the wrong section.

I don't really know how to explain this issue (scroll down for shorter version of the story), my entire system suddenly crashed and I was unable to start the computer again after that (by unable to start I mean nothing happened at all..). My first thought was that the motherboard had died, due to it being incredibly unstable (ram slots not working, boot issues/loops etc). I tested my psu anyways, but it worked perfectly fine, I'm currently using it in my new build without any problems.

The real issue that I was able to detect was gpu, since I thought the mobo in my previous computer was the issue (which isn't working any more, maybe got fried or something) I brought my old gpu and psu over to the new build, but without any luck, I could get into the bios using the integrated graphics, but the mobo didn't detect my gpu in the first pci-e slot, it detected my other (even older) gpu in the second pci-e slot, so I swapped them because I thought the motherboard might have been defect (also because I'm extremely stupid). This time none of the gpu's was detected. Swapped back again, nothing.. Not even the older one was detected.. So my main 480 nvidia gpu had somehow fried both my pci-e slots. Luckily I got the mobo replaced for free..

The real question now is, could it possibly be a combination of the psu and gpu? Can parts of a psu, namely the portion that gives out pci-e power to the gpu be the main problem? I'm afraid to buy a new gpu, plug it into my psu and experience this entire nightmare again. Should I just buy a new one? (don't really want to do that)

Short version:
Old computer died (complete blackout). mobo dead, psu still working. Old gpu fried both pci-e ports on new mobo. Thinking it might be the psu that killed the gpu which in turn killed the mobo, is that even possible?

Any feedback on the issue is appreciated. Sorry for long text..

Hardware involved:
GPU: Gainward GeForce GTX 480 1536MB (broken)
Secondary GPU: Asus GeForce 8600GT (still working)
PSU: Corsair 1000W (still working)
Motherboard: Gigabyte GA-X58A-UD3R, X58 (dead)

You said you had two GPUs, one was a GTX 480 (listed in post), is the second one the same one or no?

No, it's an Asus GeForce 8600GT, still working. Only uses power from the pci-e port.

I honestly think that the PSU surged the motherboard thus frying the components in the process. The motherboard and GPU are dated and probably don't support a large amount of power being sent to it... or it was because they were old anyways and didn't have a lot of life left in them, so the large amount of power just ended them. However, I may be wrong, I'm not really sure what's going on, so await someone to correct me if i am.


***IF I AM RIGHT***

you might want to look at buying newer mobos and gpus as these are more supportive to such a large power supply... and... probably wont fry them.

So basically a chain reaction of old hardware not working properly anymore? Was probably about time to replace some of the parts as they'r about 6-7 years old anyways.
Also as I said, I now have a new mobo; Gigabyte GA-H97M-D3H, this is the one that I fried the pci-e ports on, but got a free replacement because they thought it was defect. I'm currently using the intel integrated graphics, just bough a new MSI GeForce GTX 970, so I really hope it's not the psu!

Appreciate the help!

No problem. Also, the PSU should work fine with newer products (such as the 970 and that new mobo you got) so don't worry.
