So I just assembled a new computer and I have a ASUS Rampage IV Extreme with a Intel i7-3820 CPU. I have Corsair 650W power supply and I connected it to the motherboard using the 24-pin connecter and the 12V 4pin connector, I thought that this might be the problem but it seems that is correct from this question: Is the 4-pin PSU connector required? (Trying to connect a PSU to a mini case.)
So it seems that everytime I connect a USB drive to install my operating system from the USB drive the flash drive works for a few minutes and then burns and doesn't work on any other computer anymore. I am not sure yet if it is all the USB ports or just the ones built on the tower case, or perhaps just the blue USB-3 Port but now I can't afford to experiment and burn more flash drives.
I don't even know if this has anything to do with the power supply but it was the only thing I could think of.
