The guys at KitGuru have stressed this HD 5770 with FurMark and here are the results:
1 – Power consumption
KitGuru has measured the power consumption from the VGA card inputs and then the power in the graph is the power consumption of the graphics card. The TDP of a non-overclocked HD 5770 is 108W.
