it's not on the list of nvidia certified PSU's for triple SLI 8800GTX, although that probably doesn't mean all that much.

185W for every card so that's 550W pulled by 3*8800GTX. Plus your 65nm quad-core at stock speed/volt so it's 100W. TX850W has a big 70A +12V rail so IMO your rig is not a problem.

IMHO, you will be better of selling those 3 8800 GTXs, replace them with two GTX260 core 216 55 nm, and OC them to the sky. That would be less stressful to the PSU, and most importantly, the gargantuan performance increase advantage over tri SLI 8800 GTX.
