HTPC build:- PSU question

[beatsntoons]

Hi all

I'm starting to settle on a spec for a HTPC build. Actually, that's a lie, because I've settled on it.

My one question is to do with power supply. Will a 400w Corsair unit be enough to power this machine, considering there will be 6 HDDs and an SSD inside?

Thank you

CPU: i3 530
Motherboard: Gigabyte GA-H57M-USB3
RAM: OCZ Platinum 2GB PC3-10666C7
Hard Drive 1: Current desktop OCZ Vertex II 60GB
HDDs: 6 x Western Digital Caviar Green 2TB (or 6 x 3TB.. haven't made up my mind yet)
Optical: LG CH08LS10
PSU: Corsair CX 400W ATX Power Supply
OS: Windows 7 Home Premium 32bit
Case: Silverstone LC16B-MB

Thank you

I've just discovered that Windows doesn't natively support 3TB drives without tweaking, and that's never guaranteed, so won't be going with that option. I think the 2TB drives draw more power. I should still be okay yeah?
