Motherboard ATX 12v connector extremely hard to plug in?
I built my first computer last week with a Gigabyte G1.Sniper B5 motherboard, and a Corsair CX750 PSU, but I had an extremely hard time plugging in the ATX 12v connector into the socket.

Here is what they both look like: http://imgur.com/a/xtN50#0 .

I'm not exaggerating either when I say it was extremely hard to fit. If I hadn't held the motherboard from the back, it would have snapped in half, and it ended up not fitting all the way in the end. It took me about 5 minutes of pushing to get it to stay in place. I checked the pattern of each hole in the connector to the pattern in the socket and they all match, except one of the holes in the plug has no metal inside, but I don't think that has anything to do with it.

I've been using this computer for a week now and it crashed twice, but I'm pretty sure that was a problem with the GPU drivers, not the PSU or anything. But my question is:

Is this normal? Is something not compatible? I watched a couple tutorials on people building PCs and none of them have had to push hard when inserting the connector. Is there a way to fix this?

Sorry if this was posted before, I tried searching but I didn't know this was limited to the CX series, so I made a new thread. Now I found another thread: http://www.tomshardware.com/answers/id-1916258/corsair-... .

I'm from South Carolina in the US. I have to buy it from Amazon, though. I'm trying to stay under $100 and this one seems ok http://www.amazon.com/EVGA-SuperNOVA-ATX12V-Supply-110-... . I'm also looking at the link that herrwizo provided to see if I can find one under $100 that's 750w.
