Is this PSU enough?

My new rig will be:

i3-2130
MSI H67MA-E35 B3 (or similar mATX mobo with USB3)
2 x 2GB Corsair XMS3 1333
1 x SSD
1 x Caviar blue HDD
2 x 92mm "silent" case fans
1 x DVD-RW
1 x Creative Audigy PCI Express card
1 x Sapphire HD6670 Ultimate Passive
1 x Corsair CX400W (original Seasonic version)

I have the CX400W in my current rig but my boss is buying my chip, mobo and RAM as a cheap upgrade for his PC but he's keeping his PSU. I have chosen that card because I rarely game so a quiet machine is more important to me than ultimate performance.

It does state in the system requirements on the Sapphire website a 400w PSU is required, but on other mfgs of the a 6670 it says they require a 450w PSU. I have used various online PSU calculators but the results are too varied to come to an accurate conclusion so I was hoping for someone with more knowledge than me in this field to tell me if I'm going to be OK or not.

Cheers

Yep, will be fine. 6670 uses 70-80W, the CPU has a TDP of 65W. You'd be fine even on a 300W.
