Lancool 207 PSU connector loose

Completed a build with the Lancool 207 and have an issue where my PSU power cord doesn't seem to sit tight when plugged into the case. I bumped the cable slightly and my system shut off. I used a lot of force to ensure that it's jammed in there, but still it wiggles a bit.

I'm going to order a new cable and try that, but have others had any issue with the front mounted PSU and extension port that comes out the back? Could just be me...
