So, I've got four 120mm fans on my external radiator and have been toying with installing a switch to switch them from the 12v line to the 5v line. Knowing that each line has its own ground, would I need to also switch the grounds as well or could I use the 12v rail's ground for both the 12 and 5v lines?

Oh, and does anyone know if a 1200W PSU would be sufficient for a triple 780Ti setup? I'm thinking yes, but am asking y'all because I trust your judgement.
