This person is having the exact same problem as me:
http://forum.corsair.com/v3/showthread.php?t=111863

This photo explains my situation rather well:

Basically, my 24-PIN ATX Connector won't go all the way in.
It goes about 50% of the way with ease, 40% with some force.
That makes 90%. The final 10% won't go in, even with force. :-/

It's a brand new motherboard and a brand new Power Supply.
I'm definitely inserting the connector the right way round though.
I also checked if pins were bent or if something was stuck..it isn't.
I spent 15-20 minutes yesterday trying to make it clip into place. :-/
I even placed two fingers underneath the MOBO to stop it bending.
That's how much pressure I was applying and it still wouldn't clip in.
If I push any more I'll break something so I stop. Any advice for me?

1. Check if you're putting it in right side. ( clip clip side)
2.If it still doesn't fit then separate 4 pin connector and just install 4pin at its right spot. If it fits perfectly check for the bent pins on motherboard or bent connector slots on cable.
3.Compare sizes of 4 with 20 pin connector of psu.
4.If sizes are same Many times people think they are applying enough force and applying bit more will damage the motherboard.It wont break the motherboard just apply more force and don't forget to support the motherboard from the back with your hand and it will fit in perfectly.

I had similar problem with my Corsair CS 650m I though I was applying too much force and it will break if I put in more force to fill that last 1/2mm gap.
But I took my computer to technician.He was able put 24pin connecter 3 times but with much more force
and it works fine.

I would unscrew the motherboard from the offsets,and lift it out so I can get a proper hold of things and safely use both hands. If it isnt seated properly there is a small chance the conductor pins could heat up if the contact area is smaller than it should be. This could cause damage to the board and plug. You could try a tiny drop of
silicone lube wiped on the outside of the plug first.

I hurt my fingers yesterday if that helps clarify just how much pressure I am using. It won't go any further. Nothing's bent and nothing's blocking the way (I've checked). The fact it goes in 90% of the way means I must be putting it in the right way as well. But no matter how long I spend trying to clip it in 100% of the way, it just won't budge. It's in far enough that I can't pull it out without using some force, but it's not clipping in. I daren't use it in it's current state as I've read that it needs to clip in or else it's a risk. I've applied as much pressure as I can...I am a first time PC builder so any other advice? It took me long enough to get the motherboard in after the I/o shield kept pushing it back. It's now in thankfully but I really don't fancy the idea of taking it out again, that's for sure. The YouTube videos I've watched show the ATX connector being put in from inside the case. I've read that quite a bit of force is needed to get it to clip but I didn't expect quite this much. I've tried wiggling it from side-to-side (that's how I got it to go from 50% of the way in to 90%).But it won't go in any further no matter how much force I apply. I've even hurt my fingers trying. The 4/8-pin connector went in fine, though, with hardly any force.

I'm having exactly the same problem as you. I can get mine so that I only need to push it a few millimeters to clip on but no matter how hard I try it just won't go that extra 2 millimeters. The best way is to probably fiddle about a little with all the pins and then try. I'm going to try that aswell and I'll let you know if I get any results

Actually, with a bit of brute force it will go in eventually. I gave up as was afraid of bending the motherboard to the point of damaging something but someone else who has built computers in the past came along and just pushed it into place. The motherboard did bend and he did have to apply a lot of pressure but it did clip into place. No bending of the pins should be necessary, it's just sheer pressure you'll need and I'll admit it requires more pressure than I/you may be comfortable with applying...but apply it anyway and it will go in. ;-) Don't try and tweak the connector in any way as that might damage it.

I did what you said and applied a lot of force, using my finger to stop the board from bending too much, and I've managed to get it extremely close to clipping in but it's refusing to move that last millimeter. I decided to see if it would show any signs of life so I plugged it in and turned on the psu and almost instantly the power light on the board lit up. Before I turn it all on I wanted to ask if anything would be damaged because the connector is still technically not all the way in?

It's never safe to operate unless it's clipped in as it could come loose. Some people might argue it doesn't matter as long as it can't easily be jogged loose, so to speak. But in all honesty, I'd never attempt to power it on unless it's firmly clipped into place. ;-)

Agree with the post about supporting the back of the board after unscrewing it.
Disagree with any suggestion about using silicone lube.
Silicone is electrically conductive and it creeps and creeps and creeps until it spreads itself out one molecule thick so a drop could cover a vary large area.

If I absolutely had to use a lube on a board I'd try for one that is not conductive like cable pulling compound. But you won't need lube.

I have same issue with Corsair CX430 I bought recently. MB is Asrock H97M Pro4, which is also a brand new. only 24pin connector has such an issue. I did clip it in once when I tried to test the MB, CPU and Mem without the case. But after I moved them into case, never succeeded.
Now pc is still working well. Any good approach to clip it in?

I currently have this problem with my PSU, though i have tried MASSIVE amounts of force and it simply will not budge. anyone else with an idea other than brute force.

I've done it! The pain on your fingers will be too much to push it all the way in, however if you use a flathead screwdriver to push in all the sides while having your other hand on the back of the the board it'll go in. Be VERY CAREFUL to make sure the screwdriver does not slip and hit the mobo!

I got that with my RM750i before, somehow the Corsair 24-pin cables really don't fit in... Try taking your MOBO out

Hi there
Its not great that connector is not 100% all the way in, but as it isn't loose you should be ok.
In other hand you may bend your mobo too much and it wont work at all.

I have had the same problem with my CX550M, and it took the amount of force to the point where my fingers went numb and it took 35 minutes, but I got it in. It didn't audibly click that much, though I don't think it would with that much force being applied to it, and it is only about 1/3mm off of the connection point, and the system works 100% fine.
