Wow this card is very strange. Last night before going to bed wattage was 107W for entire system. This morning wattage was 96W. I know these cards do something called a long idle but when checking the temp history it had stayed at 70C. Looking at the Mhash, average was unchanged @ about 205mhash for 1100mhz core.

I guess shutting the attached screen off on these cards drops their wattage down a lot? With the long idle this puts this 7770 at about 71W total for 202mhash. Pretty good!
