Recently my power supply overheated, this caused something to melt and produce a very bad smell. After ordering a new 550W power supply and wiring up all the connections, when turning on the computer a capacitor decided to ignite, causing a smoke cloud and destroying the graphics card (GTX 760). After reviewing what went wrong and plugging in a 630, the new graphics card worked fine. I do remember a cable was touching the graphics card and the area of damage was the same area where the cable was touching.

 

Was the cable touched the graphics card the issue or was it something else?

You mean the pci-e power cable going to the gpu touched another wire? If so that should not have caused the problem, as all those wires are insulated...

Wires shouldn't have caused it as they have insulation. If the insulation was damaged and the bare wire was touching something, that would cause a short.

I have a picture here of the damage and the wire type.

 

 

Looks like its a wire that connects to a fan

Would you post that photo please?

That cable in the picture above was touching here :

Can you see any damage in the wires at all?

The cable was heated, causing it to melt a little bit however I can not show that due to bad camera quality.

But can you see bare wire?

No

Is there any way that you can show the damaged insulation on the wire? The insulation shouldn't have melted at all.

I believe you are correct, I was not in the right frame of mind when the capacitor ignited. After checking now, I see no damage

I'm not sure what happened that the capacitor would do that, but I do not believe that it was caused by the wire touching it as they're insulated to prevent that sort of thing.

The capacitor or whatever component may just have went coincidently an have nothing to do with the wire?

I'm almost 100% certain that's what happened.

That is what I am trying out as the power supply did fail so it could of overcharged the graphics card.

Wait, you said you ot a new power supply then this happened, what PSU did you get and where did you buy it from?

 

I got the https://www.amazon.co.uk/Corsair-CP-9020102-UK-CX550M-Semi-Modular-Bronze/dp/B01C3FFLZ8/ref=sr_1_1?s=computers&ie=UTF8&qid=1462102900&sr=1-1&keywords=cx550m+corsair

 

When connecting everything, I pressed the power on button and the component ignited. When putting in another graphics card that had no connectiong to the PSU the card was working fine.
