430w Enough?

[kilo_17]

I may be getting a Seasonic 430w power supply sometime, and after I got my 6850, I got to thinking, and was worried I'd be stressing the PSU too much. What do you guys think? Specs below:
Athlon II X4, 2 WD Caviar Blues, 4gb RAM, MSI 880GM-E41 board, Radeon 6850, DVD drive, and a few extra fans.
Thanks for any input!

430 will be miles above what you need unless you looking to go SLI ?

Not for quite a while, my board only has 1 PCI-E 16x slot, so I'd have to upgrade the board before I would do CrossFire.
