Its also interesting to watch the power fluctuate as it switches Algos. Here is x16r on my rig running for about an hour. Wattage is all over the place.

I grabbed this from a power meter that also does data logging off ebay for 35 bucks and just started playing with it on my miner. I am going to get another as I see someone has them for 25 bucks now. They are discontinued, and no longer supported, but a great meter for the price if anyone is interested. They can sample rates up to once a second. And you can also input your price per KWh and it will keep track of your cumulative costs, and also your average monthly costs. I was using a kill-a-watt to track power previously and writing it down in a notebook. Here is a quick review I did on it if anyone wants to check it out.
