Is this PSU okay for me?

[rsimp7255]

I plan on getting a OCZ PowerStream 520W from newegg.com (Rebate special til the end of the month). Will this be enough juice? Any other recommendations?

Here are my specs:
MSI K8N Diamond Plus
Athlon 64 X2 3800
EVGA 7900GT (will run sli in near future)
2 Gig Kingston Hyper X DDR400 (PC3200)
160GB Maxtor DiamondMax Hard Drive

Thanks!
