- Yes your pc can handle it, the power supply is sufficient and I
can't see any incompatibility issues
- This is harder to know. Chassis dimensions aren't always perfectly accurate so I recommend opening the case and using a trusty tape measure to be sure. The card is a small one though so you should be absolutely fine. One thing to note is that the fans on custom cards may be slightly larger so just be careful with the clearance but again you should be fine. This card also takes up 2 of the small metal brackets at the back of your pc so make sure there are 2 free.
- Yes as said in answer 1
- No your GPU has built in fans that will cool it separately. Maybe take the chance to give your pc a clean out with a can of compressed air when you replace the card though.
If you have any more questions just post them on this thread and I will be happy to help.
