I have that exact same proc in one of my nodes:

dell r630 2x E5-2680v4 128gb ram 8x spinning SAS drives 1x quadro K1200 dual SFP+ nic with SFP+ modules

power consumption: 168w was 108-124w before the K1200 gpu.

I'm going to hopefully pull those 8 disks and swap in 4x SAS SSD's this weekend, hopefully get my power consumption back closer to 100w. Then I'm going to throw in one or two T1000 8GB GPUS so I'll probably be back up to to 175-200w but thats damn impressive for the compute capacity of that box.
