Negative. The AX is the superior PSU. The two are actually almost identical except the AX has a higher efficiency rating and generates less heat overall. Slightly less line ripple on the AX also.

the ripple from both of the differs from 18mv -25mv ....thats almost zero difference...
vregs need stable 12v and fast response...the cwt based hx850 has good TR

also the hx850 has a tighter voltage regulation than the ax850...
hx850 0-100 only drops 60mV
ax850 0-100 drops 230mV

efficiency doesn't mean much....both psus can do 85% on full load...

your hardware isn't power hungry...you're alright with the hx850w

I would think the 850W will be more than enough until you start LN2ing both GPUS as well ;) Even then it might be enough...

I am running a 750W corsair for a 920 (not DIced yet) and a beefy 4890 cold air benched :) Had problems with a low Q 650W though.

I am not a fan of corsair PSUs overall... but they get the job done. My complaints are with the connectors they use (oversized IMHO broke a fan controller and thought I was going to break a video card with two different units)

I think the psu is the one area of investment you don't skimp on, personally. Motherboards, procs, gpu's come and go like the wind, but the psu is loyal to the cores.

Ordered a new Antec 1200. Hope she's up to the task. Thank you everyone for your help. ;)

I sure hope so. Do you have any experience with it?
