I just got all the parts to my computer and I was almost done putting everything together and when I tried to connect the power supply pins into the CPU 8-pin receiver and the 24-pin motherboard receiver some of the pins don't match up. There are 2 kinds of pins one being square and the other having one round edge. Now some of these do match up, although some also do not match up on both the 8-pin CPU power supply and the 24-pin power supply. So since of these pins do match and some do not should I just force the power supply connectors into each or what?
