Question on how to chose the right power supply rating for Nexus 9k

Think this is the kind of stuff that no CCxx teaches but comes from designing more networks.

I'm trying to put together a BoM and for the power supply for the 9k I see an option for 750W AC, 1100W AC. Aside from the obvious, what would be a reason to choose the higher power supply. Is it only if the switch is expecting to be very busy?
