24 Pin Connector won't go in fully

[Saltyboi]

This is my first build that I was doing, and everything was fine until the 24 Pin Connector wouldn't go through fully! It has about 1 mm left to go in fully, and I've read other posts but none seem to work. My power supply is a EVGA 450 B and my motherboard is a MSI h110m pro-vd.

As long as it sits VERY tight, there's nothing to worry. Sitting next to my new build, could tell you there's also 1mm gap between plug and slot, and it boots up no problem.
