If they're running from a PCIE1x/4x slot, the power reading is incorrect, as it gets additional power from a riser.
In my case, both 1060s are using between 100-110W, deducted from a killawat meter; yet GPUZ reports 107W for one plugged in teh PCIE16x slot, and 63W for the one plugged in the PCIE1x slot.
I'd be surprised if risers affected anything (other than slowing the cards down and reducing power consumption)
The power sensors are on the card and don't care whether the power comes from the slot, the riser or 6/8-pin power connectors. However, I'm not sure if they are pre- or post-VRM and whether the losses there are included.
The difference between killawat and GPUZ is likely down to PSU efficiency.
107 + 63 = 170 W total for GPU. Assuming 85% PSU efficiency, then you have 200 W from the wall as shown by the killawat.
