Im having a lot of trouble plugging in the 18 pin part of the 18+10pin motherboard power cable that goes into the PSU. The other part and cables for GPU, CPU plug in fine into the PSU. The 18pin part just doesn't go all the way in and feels so close to clicking into place but doesn't. Similar problem for the other side of that cable, the 24pin that goes into motherboard, also being unable to click in. Any suggestions?

Connect cables to PSU before installing in the Case
They can take a bit of pressure to insert and make sure 24 pin is correctly aligned and just push till it clicks

The problem is that the cable doesn't fit very well outside the case when plugging into the PSU. It's incredibly hard to force it into the PSU. Same for the motherboard connector. I've measured the force I used pushing down on the cable to be equivalent to a 15kg mass on a balance. Surely this isn't normal?

I don't have this particular PSU so please don't take my word as gospel, but I know on two other modular PSU's I've owned that sometimes the motherboard cable doesn't give a loud snap like the other cords, and sometimes it can look like it's not in there correctly. I eventually just stopped pushing and turned it on and it works fine. No explosions or fires under stress testing so far. That's how I found this thread because I'm easily worried (hard not to be when it comes to PSU's) and was afraid I pushed them in too far.

BUT AGAIN I'd wait until someone who has owned this particular PSU chimes in, because every one of them is different and I don't want to give house burning advice. I just wanted to share my experience in the hopes it helps ease your mind a bit.
 
Not much of a solution for brand new products. It's just how it is. Generally brand new stuff, not just computer components, will require more force on the first few uses until the material gets bit used up.
I'm on my 5th PSU in the past few years, first time it's MSI, and motherboard 24pin specific plug was not any different from other brands I've used. Tight tolerances, big plug.
 
Just double-check the connection they are a tight fit but will fully insert

I'm having the exact same problem with this same PSU. I managed to connect the motherboard cable to the PSU after 1 hour of pushing. But, not it's time to connect to the motherboard, and I'm having the same issue. The problem is, If I have to do the same amount of strength I did on the PSU side... I don't know if it's a good idea. Even if I support the back side of the mobo preventing it from breaking, what about when I had to unplug it? It'll be a near breaking experience every time?
Ironically, the mobo is also MSI (Pro-VDH Wifi).

I still can return the product and get another one, would that be a good idea?
 
Hi
I would suggest you contact retailer about this and tell them of the issues you are facing. Also link them to this thread. So in case you do end up damaging the product, you could potentially still "win" as it would appear to be a manufacturing defect.
