I was installing my new hardware in my new build (e6600, 4g patriot extreme, radeon x1950 pro, msi p965 platinum motherboard) , I finished wiring the front and turn it on and all I head is POP POP POP and saw sparks flying out of it. I think I have narrowed it down to what has happened and I just just need someone to confirm that doing so would cause this damage. I think I accidentally plugged the power cable for the gpu into the spot for the cpu without realizing it (cant believe I did that). I was also wondering what the damage might be as I have no way to test it yet. I threw the power supply back into my old machine and I wouldn't turn on so I now know that it is broken for sure. Anything at this point would help. hope it only the power supply.
