Yes I agree. But there is one problem you forgot to tell us what your PC is. As I can't say if that card will work because you could have a AGP on your MOBO.
What I am agreing too is it needs a 6 pin power connector in order to work plus if you don't have a 6 pin comming from your PSU it probley is not strong enough to run that card.
You need a 400w or better PSU that supports the bigger cards. Get back to us with your specs and for sure we will be able to answer your question and recommend a PSU to go with that card. Good luck
