Correct PSU for 8800GTX

I am going to be getting a new video card to go into a barebones build that I am thinking on purchasing.

I am scared silly of not getting the correct PSU for this video card.

One site I visited showed this as the requirements for the card:

"A minimum 400W system power supply (with 12V current rating of 30A)
2 6-pin supplementary power connectors"

When looking at various PSU's I haven't found one yet that showed two six pin connectors in the description.

Sorry for being anal here, but this is a big purchase for me and I would like a recommendation on what I should be looking for or possibly misunderstanding.

Thanks.

I just found mpilchfamily's PSU Reference List, thanks anyway.

PSU Reference List

Oh wow. I was actually thinking of writing something like that.

I already wrote down most of those prices and specs myself while searching for my PSU.
