I forgot: biggest risk in unfixed pcie cards no matter how small is that sooner or later youll pull the videocable or bounce the wifi antenna (if wifi card for example) by accident and kadapoof, misalignment, shorts and the end of card or worse...
 
On the vidcard, if its dual slot and has 2 holes, us them both. Just using the upper one just makes a nice pivot point.for sag

Thing is, temps in case will go up and down causing all things to expand and contract. Worst case: you forget about it and the wriggles in a bad way out of the slot (hyoothetically speaking).
 
Best bet would be to have a more experienced builder try to fixate it - chances are it fits just fine (i always need to "jiggle and wiggle plus exact amounts of fiddle" to get cards fixed. Youd exctually be surprised how much wiggleroom is there but if your insecure or inexperienced it better to have someone do it who knows what "bit of force/wiggle" is normal.
 
If your help also has trouble it might help to losen the mobo screws a bit, likely allowing just enough wiggle there to make the slots align more with the cases slot openings (dont forget to tighten the mobo again when done).
 
Needless to say, disconnect mains before attemoting anything as a stray screw bouncing or falling may end up anywhere.

If the video card is heavy enough, this can happen.

it sags.   which can damage the pcie slot on the motherboar

It should work

Thanks so much for the help!
The issue has been fixed. I hope to continue my PC build.
