It seems as if this 24 pin connector on my asrock z77 extreme4 motherboard is too large or something, as the connection coming from the power supply will not stay locked in place in the motherboard. This has been the case for two power supplies that I have had, and I believe it is the reason that the first one I owned died. I'm just trying to make some sense of this as I haven't seen much about this problem online, thanks guys.
