power supply that killed my computer components

So bought the Corsair VS 550w<br> <br> For a month all seemed good ..<br> Few weeks back i just get a black screen and screen goes into stand by mode but computer is still running.<br> So i restart and the screen stays this way,plug out the power from the power supply and plug back in ,comes back on.<br> <br> Computer a week after starts to restart every hour at random and booting to the POST and stating surges are being detected.<br> Go into BIOS and asus stats show where it should be 12V it is doing 13.8-14.2V and keeps flactuating.<br> <br> Took another power supply and power was at 11.89V<br> Sent in the computer and the techie stated\the motherboard seems to have gotten damaged this could be from bad power supplies "<br> <br> So Corsair power supply fried my motherboard and my i5 2500k wont work on newer motherboards cause of socket changes.<br> <br> Very very dissapointed as this is going to cost me a lot to fix!
