If it hasn't been certified, how do you know it is really X,XXX watts ?
I know there are heaps of parts being advertised as "SLI Ready", but "SLI Certified" parts reduce risk even more.
... and hey, there are some damn fine PSUs on that list at good price points too.
Possibly including the one the op mentioned, and several others they have been considering but didn't mention.
[I am gradually re-fining the reply btw, minor edits, etc]
For a single GeForce 8800 GTS the Antec Neo HE should be OK.
However for 2 x GeForce 8800 GTS one should really be looking at these PSUs:

As the OP has a SLI capable mainboard, and is looking at "SLI Ready" PSUs I am going to assume they eventually want to SLI 2 x GeForce 8800 GTS - ... in which case they should be after one of the above PSUs.
