Wondering if I have enough juice to power up a 4870 or not

[butlerguy1990]

The old lady is going to buy me a 4870 for christmas and I wanted to make sure I have enough power for it or if im going to have to pawn off my old PSU to her new computer and get a better one for my PC. Right now I have a 580 watt PSU, if this isnt enough what should I get when I do upgrade to a better one?
My Setup.

AMD Phenom 9850 Black Edition Quad Core
8 GB of OCZ Reaper DDR2 1066
2 Sata hard drives
1 IDE Dvd burner
Case:Antec 900 with all 5 120 mm fans and the 200 mm fan running

Thanks for the help

mmm.... sounds like youd be cutting it close. enter in your system configuration into the power calculator and find out:
