First off, Welcome to OCN!
Its a great place.
Now to get to your question.
1. You will get a performance hit, but, it is pretty minimal. These card's capped at an x8 lan bus will just result in an fps drop. But, trust me it isn't too much to worry about.
2. That power supply should be perfectly fine. Although I would consider maybe getting a better named PSU for future proofness. (Corsair; PC P&C)
3. I dont see why this would be a problem, the cables should be putting out power and it shouldn't matter if its a modular cable or not. You should be fine.
You should be maxing out games at 1920x1200 with exceptional framerates.
Hope this helps.
