Asus 4870 dk power supply

[Guest]

hi, i have a 450W power supply, and my asus 4870 dk requires a 550w minimum,

so the performance will not be like the working with 550w? i mean is it a huge difference or just a lil

Ignore the 550w "requirement" as it has absolutely nothing to do with reality. What matters is the brand/model of your PSU and how much voltage is available on the +12v rail(s)
This info should be on the side of the PSU.

and the question is, will it make a huge difference or not?

for example in nba 2k9 i put everthing hight..but when it comes to player (ultra hight) its so slow

Well the card will either run or it won't. It uses a certain amount of power for regular operation and more when used to play games. If the PSU can't handle the card at all the system won't start up properly. If it can't handle the power needed during games your computer will shut down when you try to play.
If you already have the card and none of that is a problem then you don't need a new PSU and getting a new one will make no difference in the card's performance.
