I was checking the ATI 7750 card on gpuboss and found this information:

TDP 55W
Idle power consumption 104W
Load power consumption 216W

I don't understand what TDP is and how it relates to power consumption. Also what of these values should I keep in mind for choosing a PSU?. According to wikipedia:

Quote:
The TDP is typically not the most power the chip could ever draw, such as by a power virus, but rather the maximum power that it would draw when running "real applications".


So, how does TDP relates to power consumption?
Thanks.

The load and idle power on gpuboss is the total system power on the pc they are using. Here is power of just the card. http://www.techpowerup.com/reviews/ASUS/HD_7750/24.html Tdp is not actually related to power consumption but rather heat. The card would created a max of 55w of heat. Although you can typically use the tdp when estimating power needs. Nvidia actually states power consumption while other companies are still stating tdp.
