Will this power supply be enough for my system?

[leglez]

I am about to build a new computer, here is the list of everything.

Thermaltake M9
Gigabyte GA-P35-DS3L
Intel Core 2 Quad Q6600
Geforce 7300GT I plan on upgrading to an HD4850 by November
Kingston 2GB I am going to start with 2GBs and then when I purchase the new GPU I plan on getting 3 more sticks of this
Arctic Cooling Freezer 7
I am starting with 2 300GB Hard Drives, and going to also upgrade to 2 x 1TB HDDs when I upgrade the RAM and GPU, so I will have 4 7200RPM HDDs

On the NewEgg PSU Calculator It says I am going to need 806W

I planned on just getting the600W OCZ StealthXStream but now I am worried it wont have enough power, I am not really wanting to spend much more because I am already $200 over my original budget.

Did you use the 4x HDD and 4850 when using it? No, it doesn't need 806W. Right now with a 7300GT and two HDDs you only need around 350W or so. With four HDDs and a 4850 you might need around 500-600W. Buying a good quality unit is key. Also, not a terrible idea to get a hair more power than you need, so maybe 650-700W, in case you end up finding a good deal on the 4870 or something better.

Do you happen to have any suggestions?

Actual suggestions? Corsair 650TX, BFG LS-680, PCP&C Silencer 610, Antec TruePower Trio 650 (only if it is on special, which happens every couple months). If you want to go a bit higher wattage, Corsair 750TX, BFG ES-800, PCP&C Silencer 750, Antec TruePower Quattro 850 (if you don't mind the noise).

Thanks! I think I am going to go with the Corsair 750TX
