Video cards

I picked up a video card. In the characteristics: TDP - 75 watts, recommended PSU - 400 watts. She has no additional food.
I read that TDP is not consumption, but heat dissipation and PSU will not help. Then how to pick it up? And on what grounds is the recommended PSU - 400 watts, if more than 75 does not pull PCI-E x16

The recommended power is for the entire configuration and in general it is a very conditional thing. Open any online computer assembly calculator, enter your configuration, it will calculate the required power for you.

TDP - thermal design power, yes, this is heat dissipation.
Moreover, the value is not regulated by standards. Someone considers it as the maximum heat generated, and some marketers of the same Intel under TDP mean the average heat dissipation in some of their tests.
But heat dissipation and power consumption are the same with a small error - almost all the energy consumed by electronics is converted into heat.
The recommended PSU is indicated in total for a typical system, and not just for a video card. In addition, with a very large margin for many power supplies of extremely dubious properties.
