Last piece to my PC upgrade - PSU

[railven]

Hello,

I just had a quick question:

Would the Corsair 650W be enough to run the following:

Intel Core i7 930+stock cooler
ASRock X58 Extreme
3x2GB DDR3 1666 (G.Skill Pi)
2xHDD (500GB SATA II, 160GB SATA I back-up)
SATA DVD-RW (plain vanilla)
ATI Radeon HD 5870+stock cooler
3x120 System Fans

future upgrades, when possible not a given:
second ATI Radeon HD 5870+stock cooler for Crossfire
second 500GB SATA II for RAID
Corsair H50

Or should I upgrade to the 750W?

Thanks, will be placing my final order today.

750W for CF, 650W for non-CF.

750W for CF, 650W for non-CF.

+1, you might want to just head up to a 750watt if you know that you will pursue those upgrades. It's easier to pay more now than have to go through the hassle later.

Thanks, will upgrade to the 750W.
