using nvidia-smi to retrive power information for [Quadro FX 5600]. a question

I am trying to use nvidia-smi -q -d POWER to achieve power information for Quadro FX 5600. However , here is the output:
==============NVSMI LOG==============

Timestamp : Fri Sep 30 16:59:31 2011

Driver Version : 270.41.19

Attached GPUs : 2

GPU 0:6:0
Power Readings
Power State : N/A
Power Management : N/A
Power Draw : N/A
Power Limit : N/A
GPU 0:7:0
Power Readings
Power State : N/A
Power Management : N/A
Power Draw : N/A
Power Limit : N/A

But it works for other parameters such as memory, temperature , etc. Then I use out of band method to record power consumption for the whole quadro box ( using external meter or PDU). I am also wondering whether the power value I got includes both GPU chip power and PCI power , or it is just GPU chip power since it is an external box and it seems external power supply is the only supplier for GPUs.

That won’t work on the 5600–we don’t have power information available on that card.
