Force needed to join 24 pin connector and mobo?

Hi,
I am currently building a custom pc following this guide: http://goo.gl/8hBgbR
Around the 13 min mark it talks about plugging in the PSU to various parts of the motherboard. The PCI E cable is firmly in place in my graphics card, as is the cable that goes to the CPU. However, the 24 pin connector cable isn't fully in place (you can physically see this due to the fact that it isn't 'clipped' on a latch at the front of the socket). I've tried applying a medium amount of force to no avail, and I'm at the point where I feel that if I try to push it any more something will break.
Also, I think the connector not being in is the reason why when I try to perform the steps at the 14-15 min mark in the video (booting up mobo using screwdriver) nothing happens.

Any suggestions?

Apologies if I'm a bit vague or unclear with anything, this is my first time in these forums as well as my first time building a computer.

They can be tough, show that thing who's boss!

As long as the motherboard is screwed properly to the case you won't break anything trying to get it in there. Obviously don't hit it with a tool of any kind but, put some muscle into that thing!

And yes, it isn't booting because the motherboard isn't powered.

Thanks for the advice, but I'm following the guide in the video which means that my mobo isn't in the case at all but rather resting on the box that it came with. It's just a little worrying how much it seems to bend when trying to plug in the connector.
And thanks for clearing up the booring issue, much appreciated :)

That's fine, are they suggesting you build that way to test before you put it all together?

The screws on the motherboard are going to be a pain in the ass to get to with all the hardware on the board, I would never build something this way but, to each their own.

Yeah, I think the idea is that this way if it fails to boot then you can identify the component that is the issue more easily. I'm not really following this for any particular reason other than it seems to be one of the most popular and straighforward video guides. I may have trouble with the mobo later on but I guess it's too late to stop now.

Well now that you have it all "built", it's no big deal to take parts off the board to screw everything in now that you know where it all goes. Worst case scenario you have to take the graphics card out and unplug some power and sata cables to get at some screw holes, no biggie now that you've got your groove on ;)

Did you manage to get the 24 pin in there? Did it boot?

Its about 90% in, still no power :(
Maybe I'm touching together the wrong pins? There's no indication in the mobo manual of which pins control the on button

Do you have the mobo and everything in the case now?

Which mobo do you have?

If the 24 pin connector is in and "latched" and everything else is plugged in, then you should be ready to rock. Are there any LED lights on your motherboard that turn on when you turn the PSU on? At least you'd know if the board is getting power.

Send me the mother board and I'll see if I can find it online somewhere.

Mobo is: MSI B85-G41 PC Mate ATX LGA1150 Motherboard

The 24 pin connector is literally millimetres away from being latched but I figured that as its in very tight at the moment it will be ok(?). I don't see any LEDs on my motherboard when the PSU is on. I'm currently still working with all the parts outside of the case.

Thanks in advance if you help me solve this.

You really need to make sure that bad boy is latched in there.

In your manual, go to page 1-24 in chapter one, it talks about the JFP1 and JFP2 connectors. This is where your case LED's, front panel power and reset switch plug in. If that isn't plugged in, that's why your button won't turn the system on.

So, make sure all that's plugged in properly, and make sure the 24 pin is secure. If you're not sure about the case wires, the case should have come with a small manual that tells you which ones are for what.

I haven't found yet if your board is supposed to light up somewhere, I'll let you know if I do.

At the moment I've found the JFP1 pins and as I'm working outside the case I'm not trying to boot with the on button but instead by connecting the two pins with a screwdriver (same effect). I still have nothing turning on when I do this though. I've looked around and it doesn't look like there's an LED in sight, but I could have missed it. As for the 24 pin connector, I'll give it a bit more force but it really seems to not want to go in any more.

The psu is on, and selected to the correct input? Some of them have the option of US or European outputs on them.

I can't find documentation on your board as far as an LED goes either, if it was my build, I'd be throwing it all in the case and putting it together the way it's meant to be and trying then, but there's a chance you'll do all that work and still have a defective part somewhere.

I don't think there is any option to change region, PSU is definitely on. Before when I had my 24 pin cable in a few tries ago, upon turning on the PSU all the fans (of the psu, gpu and cpu) would come on for a split second then turn off. This doesn't happen any more - there is no power at all.
I was considering putting it in the case but I think the problem will still remain so I'm keeping it out until I get it fixed.

Do you have a known good PSU you can try out? I know you don't want to put the stuff in the case but, just for curiosity's sake, can you put the case close enough to the board just to hook up the switch? There's a good chance it won't make a difference but you never know with this kinds of things.

If there's no power at all now, and you had some before, it sounds like it could be a fried PSU but, I'd check it on a known good PC if you have one available.

I've tried my 3 pin power lead (kettle cable) on a different PC and it works. As for booting the PC still no luck, although I still haven't connected to my case yet.

That's a bummer dude.

If the other system has enough juice, try that psu and see what happens. The different cables are on different power rails in the psu so, the 3 pin harness might be fine but the 24 pin or 8 pin to Cpu may not be.

Have you tried unplugging the power to the video card to see if it posts?

Also, might be worth booting with only one stick of RAM. Usually the board will beep if there's an issue with either of these, not refuse to boot but, you never know.

I'd try the case button first before any of that though, simply because it's the least work.

MEGA EDIT: Went through and unplugged and replugged everything. The parts are still out of the case but the case button is attached. Now pressing the on button causes everything to turn on for about 2-3 seconds, at which point it all turns off again.

Any ideas? I consider this to be a step forward from where I was yesterday :p
NOTE: I've checked the PSU on it's own using a paperclip and it works. The 24 pin connector issue still exists though :(

Paperclips only prove that power is there, not that it's enough power to provide juice to the whole board.

You need to have an entire known good PSU in there to really know for sure, but until you have that 24 pin in there securely, there's really nothing else you can do. You can't rule anything else out until that's plugged in properly.

If you aren't comfortable getting that thing in there, see if one of your buddies with experience can give you a hand.

You've got to plug it in man. Just put ur hand on the back of the motherboard right behind the 24pin plug and then push till it locks in place. It will take a good deal of force. I've built several computers and in all of them you need to put a good deal of pressure. Ram is the same way

Hi all,
Firstly, apologies for the late reply. I appreciate all the help that everyone has given me.
1) I've got my computer to run. The power cable isnt fully in (still ~80% in) but with some wiggling power is given to the motherboard. I realise that this isn't a long term solution but is this safe?
2) I've tried wiggling and rocking the connector in every possible dimension, including the ones that are yet to be discovered. After a certain point (the point that it's at now) no amount of wiggling will make a difference.
3) Specifically in reply to thedarkshadow - I've tried using a fair deal of force, I would say 2x the amount that I used for the RAM with no luck. I really think that putting any more force in may damage something.
4) I've checked the plug and socket for bends. It all looks fine - I'm assuming if there was a bend it would be pretty easily visible?

Sorry if that's a lot to take in, my main concern out of those is No. 1 I suppose, as it affects me directly now.

Tl;dr - is it safe to run with my 24 pin connector mostly but not fully in if power is being supplied successfully?
