Help! Is my future PC builds components compatible with each other?

Solution
Everything is compatible and will work/fit. My only suggestion might be a better power supply. For around $10 more you can get something like this evga b2 unit.

The wattage is overkill but it's not undersized and getting a more appropriate wattage would only end up costing more. It won't really pull any more power than you use so no issue there. The rating doesn't indicate how much power it's going to pull from the wall, an 850w won't automatically require 850w at the wall vs a 500w unit. It does make use of a mail in rebate though so if you're not comfortable with that it might be worth looking at other units.
