My PSU Exploded, What could be the cause?

I just got a brand new seasonic x650 650 watt gold power supply, plugged it all my system, it run fine for about 20 mins, I was in the middle of browsing and watching youtube , then all of the sudden the computer turns off and i hear a large pop and see a small flash of light. What could have caused this explosion?

It was running fine for twenty minutes, no sounds or smells or anything. Then kaboom. I'm afraid to turn it back on again for fear of frying the other components.

Here are my System specs
i5 4570 @stock frequency
gigabyte z87-d3hp motherboard
gtx 560ti @stock frequency
2 sticks of 4gb ddr3 1600 ram
1 intel 530 series ssd
2 western digital caviar hdd.


As you can see it's well within the load parameters for a gold 650w power supply.Sadly I won't be able to place a claim for warrantly until monday, tomorrow. Any help or insight into this issue will be greatly appreciated.

More about psu exploded
  1. Have you double checked inside the case to see if everything was plugged in alright? Can you feel any burn smell?

    Also it could be that the PSU received a peak of electricity from the wall plug and exploded so the system wouldn't be damaged. Do not turn the PC on again as the PSU might be damaged.
  2. I would say it was just bad luck. All components, even quality components, have a failure rate.

    Just looked through my case, nothing seems to burned thank god. Though only turning it on again, will really show if any of the other components are broken. Hmm I am running it over an extension cord. Though My last psu a seasonic 600w bronze ran on it fun for three years without any problems.As for a power surge, I'm not sure there was any power surge, the lighting in my room didn't flicker nor did my aircondition go haywire.

    An electric peak can pretty much happen without a power surge, it's called dirty energy. This happens due to conditions on the electric power station which provides energy to the area where you live. But if your previous psu worked no problem, you must have gotten a bad unit, just bad luck.
