You could probably get away with a 650W, but a 750W would give you some breathing room. Check out the extremePSU calculator lite to see what you think would be best.
Here are some high efficiency recommendations at both power levels, all of which are either Gold or Platinum efficient and all are modular or semi-modular.
650W:
Rosewill Capstone 650m: $89 after MIR plus $15 instant promo: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182263
Seasonic G series 650W: $116

750W:
Corsair HX750: $129 after MIR, plus $10 instant promo
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010
Rosewill Tachyon 750W (Platinum level efficiency): $115 after MIR
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182273
Rosewill Capstone 750m: $99 after MIR
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182264
EDIT: geofelt is 100% correct in not needing more than 500W if you do not SLI. I was recommending options for SLI, but I tend to agree with geofelt that it is not really worth it.

A GTX670 needs only a 500w psu.
For sli, you will need 750w.
Buy only a quality psu.
Here is one list sorted by quality:

As to planning for sli, here is my canned rant on that:
-----------------------------Start of rant----------------------------------------------------
Dual graphics cards vs. a good single card.
a) How good do you really need to be?
A single GTX650/ti or 7770 can give you good performance at 1920 x 1200 in most games.
A single GTX660 or 7850 will give you excellent performance at 1920 x 1200 in most games.
Even 2560 x 1600 will be good with lowered detail.
A single gtx690 or Titan is about as good as it gets.
Only if you are looking at triple monitor gaming, then sli/cf will be needed.
Even that is now changing with triple monitor support on top end cards.
b) The costs for a single card are lower.
You require a less expensive motherboard; no need for sli/cf or multiple pci-e slots.
Even a ITX motherboard will do.
Your psu costs are less.
A GTX660 needs a 430w psu, even a GTX680 only needs a 550w psu.
When you add another card to the mix, plan on adding 150-200w to your psu requirements.
Even the strongest GTX690 only needs 620w.
Case cooling becomes more of an issue with dual cards.
That means a more expensive case with more and stronger fans.
You will also look at more noise.
c) Dual cards do not always render their half of the display in sync, causing microstuttering. It is an annoying effect.
The benefit of higher benchmark fps can be offset, particularly with lower tier cards.
Read this: http://www.tomshardware.com/reviews/radeon-geforce-stutter-crossfire,2995.html
d) dual card support is dependent on the driver. Not all games can benefit from dual cards.
e) cf/sli up front reduces your option to get another card for an upgrade. Not that I suggest you plan for that.
It will often be the case that replacing your current card with a newer gen card will offer a better upgrade path.
The GTX780 and amd 8000 series are not that far off.
