I used kill a watt to get wattage reading from each power supply when it was mining and the 1000 PSU is  at 700 W and the 850 PSU is at around 300 W. So 1000 total. I took those readings when I started without changing settings.

So now it's been running steady for two hours at power 80%, memory 400+. the two hottest cards are now about 73 and 74°C. I'm holding my breath.

It's still 80° Fahrenheit in that room I have the window open. 89° Fahrenheit outside..
