New computer build, is a Thermaltake 470W supply enough?

[ctam009]

Hi guys, I just bought the components for my new PC build....only short of a power supply

The components are:

CPU: Core 2 Duo E8400
MB: GIGABYTE EP45-DS4P
RAM: Corsair 4GB DDR2-800 PC2-6400 C4 TWIN2X
GC: SAPPHIRE Radeon HD 4850 512MB

Case: Antec TWELVE HUNDRED (1x 200mm, 5x120mmLED Fan)

Cooling: Thermaltake Duorb + Thermalright ultra 120


I originally thought my old TT 470W would do the trick

But after looking at "Extreme Power Supply Calculator", it estimated 459 W total, which is driving it a bit

and I speculate it probably won't do the trick now.


Can you guys please tell me if my concern is right?

If so, for that spec, what power should I go for?

Then, whether I should pick a Corsair or Therlmatake power supply?

Cheers!

470 watts isn't going to cut it.
