I was starting the wiring on my PC build when I decided to plug the 24-pin connector in first. I used as much force as possible without breaking the board, but it wouldn't fully plug in. When I tried to take it out, it's not moving at all, even with the clamp pressed down. Would it be safe to unscrew the motherboard and hold the back of it while I try to plug it in? Or are there any other solutions?
