Nvidia has lower the requirement for highend SLI to +12V@30A:
http://www.slizone.com/object/slizone_howtobuild_2.html
However, since we will be over-clocking, we will continue to recommend +12V@34A.

Anandtech used the OCZ PowerStream 520W for all of their SLI testing,
back when the 6800GT/U's first came out & before there was an Nvidia SLI Certified program.
THE OCZ POWERSTREAM 520W HAS PROVEN TO BE THE BEST ALL ROUND PSU FOR DFI N4 MOBOS!

These quality brands are highly recommended,
however not every power supply they offer will meet your needs,
be especially careful to make sure that the +12V rail(s) offer a
Minimum of +12V@26A for Single Video Card Systems & +12V@34A for Dual Video Card (SLI) Systems.
PC Power & Cooling (PC P&C): 1% Regulation, Adjustable Rails & 5yr warranty.
OCZ PowerStreams: 1% - 2% Regulation, Adjustable Rails & 5yr warranty.
Antec (TruePower, TruePower II & NeoPower) & Zippy: Tight Regulation & 3yr warranty.
Antec (Smart Power), Cooler Master, Enermax, Fortron, Hiper, OCZ (ModStream),
Seasonic, Silverstone (Zeus), Sparkle, Tagan, Vantec & XClio: Known Good Quality & often at Low Prices.
All of the above are very good PSU's & are recommended.
My personal choice is the OCZ PowerStream 520W for just about any highend, high-performance PC.
If you have the bucks, the PC P&C 510's are "THE BEST PC PSU's MADE".
One special note, if you require extreme quiet the the Seasonic S-12 500W/600W were made for you.
REMEMBER NATIVE 24-PIN ATX CONNECTOR & 480W's OR MORE!

http://www.thermaltake.com/purepower/W0023.htm
Why do people buy these?
There are PSU's for under $30/$40 in the "Complete PSU Guide" with more +12V amperage!
These 2 TT PSU's are the "poster children" for DFI's 480W+ requirement &
based on these it should be a 600W+ requirement!
Enjoy!
