Need a psu reallly fast

Silverstone Zeus ST85ZF 850W

Will this power supply be enough for a oced q6800, 680i board, 2 8800gtx, 2 dvd burners,
6 case fans

or would this one be ok


PC Power and Cooling ULTRA-QUIET PSU: SILENCER® 750 QUAD
 
Either are great. I love my Silencer 750 Quad (and it is indeed quiet), but it's non-modular, so keep that in mind.

Guessing at draw, I get around 360-370watts at the wall under full load. Add another 60-80 watts for the quad as opposed to my dual core, add another 120 watts for a second GTX, I have more drives and only 2 less fans (fans are pretty minor, wattage-wise). So you're looking at between 540 and 570 watts at the wall full load. Call it 600 to be safe.

(assuming 80% efficiency)
(600/100)x80=480 watts internal draw. That puts the Silencer 750 at around 2/3rds of its rated continuous output capacity. Plenty of headroom.
