question about the graphics card.

[darkgaming]

so i went to go look the cards website to take a proper look at it and on that website it says a different power W to the one it says on overclockers.

http://www.overclockers.co.uk/showproduct.php?prodid=GX-171-PC
on there it says 250W

http://www.powercolor.com/global/products_features.asp?id=540#Specification
on here it says 750W

may i ask which one is right?

Ones the Cards TDP, the other is system recommended PSU.
Neither are 'right' in themselves, ones a ridiculous over estimate the other is TDP.
