I just looked at my power meter. I'm running a modded kopiemtu 2.0 usb stick install (ubuntu 14.04) with 5x 750ti cards (Gigabyte OC with 6 pin on top), and a +125 MHz overclock on each card . With Quark on the latest commit and no -g or -i switches, power comes in around 330W total for the system.
thats a nice draw ... not much at all ...
does it change when you change algos? ...
the measurements we take is based on amperage not wattage ( though should be easy to convert ) due to the maximum amperage the property handles ...
for a similar system ( except we have ssd drives running on the majority of systems and about 6 x gigabyte 750ti oc lp ) we draw about 2.2A ...
using this calculation -
http://www.supercircuits.com/resources/tools/volts-watts-amps-converter - we ( theoretically ) draw 528W of power per machine ...
this is based on 240V ( australian supply ) and 2.2A ...
so what you are drawing is awesome ...
need to invest in a power meter for each system i think ...
