I think in some cases gk110 based cards (Titan, TitanBlack, 780, 780Ti) might draw more than 200W, Smicha, close to 300W..but yeah, TitanZ is optimised for lower draw (compared to two separate cards)..

1200W is more than enough for stable run, You need 6+8 pin for Titan(black) & 8+8 for TitanZ.
Talking about motherboard You have very good model with spacious layout. There's three slots between main PCIe connectors (red ones). This card is very stable, even with OCs - I've made a build on it's smaller sister/brother GENE (MATX version) for someOne & I haven't heard any problems since..
The the only thing that matters is Your case..If You have power supply (PSU) look whether the fan is facing up or down (some cases have one,other or possibility to choose both orientation). If You put TItanZ in the bottom red PCIe slot & Your power supply fan is facing up, You might have some problems as they fight each other for air & TitanZ might start to starve from fresh air keeping high temps wile rendering..
in short - case's airflow matters & talking a bit more about it I'd try to provide enough of it.. Titan(Black) will throw the heat out, while Titan Z will keep half of the heat in a case..if You have bad airflow that might cause some thermal throttling (lost performance).
