That 1200W PSU will be more than enough.

Here is Guru3D's power supply recommendation:

GeForce GTX 690 - On your average system the card requires you to have a 750 Watt power supply unit.
GeForce GTX 690 SLI - On your average system the cards require you to have a 950 Watt power supply unit as minimum.

If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina. On top of that my neighbor has pretty much the same build as yours well he has different mobo and monitors but you get my point i hope and he uses SeaSonic X-SERIES X-1050 1050W PSU so you will be fine
