again, it isn't measuring power. it's the suggested cooling performance. Which always exceeds actual power draw.
In the case of the 940, it exceeds it by far.
If you had a chip that consumes 125W of power, you'd need a cooling system that draws a minimum of 125W of heat away from the chip. But really, you'd want more than barely adequate cooling. In that case, AMD would probably give that chip a 140 TDP rating. Even though it's not going to exceed more than 125W under maximum load.
While the 9850/9950 would exceed the 95W maximum for the board, the 940 won't.
