Post problem with MSI Z87-G41 and CX500m corsair PSU
Today I just purchased a CX500 modular power supply, as well as some hyperx ddr3 8gb ram. When I got home I wanted to do a post test with my haswell i7-4770 cpu and nvidia geforce gtx 450, then install into the case. I installed everything fine, until I came to power. I plugged the cpu power in fine, and the when I tried plugging the 24 pin main power I started to have trouble. The plug would go in until there was about a little less then a centimeter remaining for me to plug in, and the clip wouldn't clip on to the notch on the socket. I know not to force, so I tried turning everything on and shorting the two pins, but no fans turned on. I didn't plug the video card into the monitor though. Was something faulty? or did I not do something right. thanks. The video card was refurbished if that means anything.
