I have the Asus M5A97 R2.0 Motherboard with a GTX 660 graphics card and the AMD FX 6300 Processor with the XFX 550 80+ power supply.
I am using the Rosewill Challenger Case that comes with three fans.
So I put everything on the motherboard...
You don't mention RAM. To POST, you need CPU, mobo, PSU, GPU and RAM (attached to the case). Use your manual to make sure you make the proper connections and use the right slots for the RAM. If you're not certain the motherboard connections to the case are correct, use the manual and research the case to make sure you identify the wires properly.
Hope this helps.
