Real world power consumption of a 7604-S or 7606-S

I'm finding that the spec sheet for an RSP720-3CXL says 310W for the
supervisor itself.

Assuming a dual supervisor configuration in a 7604 or 7606, has anyone put
one on a watt meter and measured its actual power consumption?

Example:
7604S chassis with dual 2700W DC power - chassis and fans use how much
power?
2 x RSP720-3CXL at 310W each
WS-X6704 with DFC4 - ???W each
