Is this enough POWER?

[STEEL_BALL]

I am upgrading m computer, and I am trying to reuse as many of my old components as posible so that I can put more money toward videocard and cpu upgrades. I already have an Antec 480watt power supply and I was wondering if it would be good enough to run these new components or do I need more power?

AMD FX-62
BFG Tech 8800GTX (i am not planning to ever run an SLI setup)
ASUS M2N32 motherboard
2 gigs pc800 ram

thanks
