650W enough?

Egg has a good deal on a 650W power supply, but I've read the guides here and I'm not sure 650W will be enough. I'm putting together a new build. Here's what I have in mind:

Asus P8P67 Pro
i5 2500k
GTX 470 or GTX 480 or GTX 580 (likely 470 or 480, the max I'm willing to spend now) single card
WD 640gb 7200rpm HD
3 or 4 Hitachi 1tb 7200 rpm HD's
1 or 2 DVD burner
Adaptec SCSI card
Azza Hurrican Tower case (has 8 fans)

Going by the guides, looks like 650 may not be enough. But someone said the power requirements in the guide were "dearly overstated." The power supply I'm looking at is http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Thanks

Thanks for the tip on the 560. Didn't know about it. Digging into that now. I've been buying these parts piecemeal as there is a sale, shellshocker, etc. so I'm in no hurry and I can wait. Was going to update my old system, but I'm just going all new and giving the old system to my wife. Usually trust the Newegg reviews, but that NZXT power supply has some good reviews going for it on the web, and it looks like a good deal. If it's enough juice, I'm going with it.

Thank you, thank you, thank you. Man, I just spent mucho hours researching power supplies. Probably would have preferred a 750W supply, but I believe the NZXT hale90 650 will be more than adequate for my new build. At $80, definitely seems like the most bang for the buck.

The only reason you'd need more than 650W from a quality manufacturer is SLI'ing down the line. For your build, you're fine with this one.
