Which Seasonic PSU?

[chrismox]

I'm building a new PC with the following:

3700 San Diego
BFG 7800GTX
2 x SATA drives (RAID)
1 x IDE drive
2 x DVD drives

I'm going to buy a Seasonic PSU and was hoping the 430w would do the job - it's cheaper (obviously) and apparently quieter than the higher models - any thoughts?

It also seems the 430w lacks the "2 x EMI shielded PCI Express VGA connectors to support power requirements of latest SLI™ Technologies within upcoming coupled graphic card generation" the the 500w and 600w have - is this a problem?

Thanks guys - not planning on SLI but didn't really want to be caught out in a year's time when all of a sudden I find everything needs more power.

The price and silence of the 430w seem to be winning the battle against future-proofing.

There's an interesting article here: http://www.silentpcreview.com/article28-page4.html

It seems to suggest that not only are high-power PSUs generally not needed by most of us, they're actually more inefficient during day-to-day use.

And I came so close to buying the 600w Seasonic in the "this week only" deal, seems like the 430w will be the one for me
