24-pin connector won't lock down?

Building a new pc from scratch, the 24-pin connector (which is a 20+4 configuration) refuses to lock into place, the 4-pin part fits fine the 20-pin part refuses and stops about 1-2mm short of clipping down.

The mobo bends a bit when I attempt to attach it, I've taken it out of the case, even setting it on the counter isn't helping, the amount of pressure required seems to be excessive... trying to remove the connector is no different. I don't want to break the mobo trying to get the connector together.

PSU

PICS OF CONNECTIONS


Doesn't look like there are any burrs/malformed moldings, etc on the connectors... I did some looking and this seems to be an issue with some Corsair PSUs, didn't see mention of EVGA/MSI pairings... any ideas/insights?

If you have room, slip the tip of your finger under the board near the 24 pin header for support while you push down, rocking the connector end-to-end. Not side to side. If it has bottomed out due to poor tolerances, there's not much you can do other than file away some of the connector's length. Not easy to do by hand.

If you are worried it isn't in far enough for a good connection, you can use a short 24 pin extension cable as a work-around solution. It might fit better in the end that is the culprit. http://www.amazon.com/StarTech-8-Inch-Power-Extension-ATX24POWEXT/dp/B000FL60AI

That happens sometimes. The header manufacturer or the connector manufacturer are off on their tolerances a bit. I have used a small file to file away some of the connector's clip's lip. Or the locking nub on the header when I could access it w/o damaging the board. But if the connector fits tight in the header, it probably will be OK w/o locking.

Not sure if the headers are making a good connection or not, I have to use a good amount of pressure to even get it down to less than a 3mm gap, don't want to fry my mobo.

Yeah, friend said to get EVGA cuz they don't usually have that issue... starting to wonder now lol

Was part of a bundled parts package I ordered, was sufficient wattage for what I planned on using it for... friend said it should be fine aside from non-modular PSUs being less cable-management friendly... definitely second guessing that now.

Managed to connect it outside the case without breaking the mobo... not taking it apart now... guess I'll just run the 24-pin cable in front of the mobo tray til I do my upgrades and go non-modular. With a couple tie downs it should be easy enough to keep it out of the way of airflow and other components (we used to do this in the not so distant past before we had cases with cable-management space behind the tray.... right?). Will definitely keep the "use an extender" idea handy for next time... at least it should let me figure out where the trouble is.

Lesson learned: go modular or go home... thanks guys :)
