There shouldn't be any compatibility issues based on your parts list. One other thing I would try is jumping your motherboard.If your system powers on when you do this that means either the front panel cables weren't connected properly something is wrong with the power button on your case. It may also be worthwhile to do an out-of-box POST test. Remove the board from the case and put it on a flat non-conductive surface like a cardboard box or wooden table. Keep the RAM, CPU and CPU cooler installed. Plug in the PSU and your GPU, and try jumping the board like I described above. This will rule out of the board is making contact with something in your case that it shouldn't be that could be causing a short.
Yeah, that would rule out the motherboard as a culprit. Only real way to narrow it down is to keep swapping components out, if possible I'd try the CPU next. Of course you're always welcome to bring it to your local Micro Center for diagnostics, just keep in mind that would be a $39.99 fee.
