The Bitfenix ones are extensions, not replacements. Personally, I have an HX1000w, which, in the sleeving community has be known to be a bit of a PITA to single sleeve without half assing it, so I chose to use extensions instead of sleeving it. Mind you, this was before Corsair came out with sleeved replacements, but whatev.
Why not just call corsair directly and ask them for what you need extra from the set. Corsair is one of the best companies in the Industry when it comes to customer service(well, when it comes to anything really), they'll probably send you exactly you need, overnight, no problem.
If you would rather use extensions, Ill vouch for the quality of Bitfenix extensions. I have an 800d case(Im a corsair fanboy, if they make it, I own it), which is awesome for cabling, so the extra length with the extensions was no problem. Plus, I do a new build every 6 months or so, and I change color schemes, so extensions allow me to easily have differently colored cables If I decide to keep PSUs from build to build. Which I do, because the HX 1000w is a beast.
Check out FrozenCPU.com They've got a bunch of sleeving items, everything you need other than the best sleeve money can buy. For that, you need MDPC-X.
Edit-hmm, I may have got off topic of your direct questions.. Sorry, Im a sleeve nut, love the look.
You cant use extensions in place of cables directly connected to the psu, they wont fit and it voids your warranty from most brands.
Second.. You should be able to use the AX1200 bundle for an AX850, just find a picture of the AX1200 socket side of the psu and compare it to the 850, make sure it all matches up. I know there is differences between the HX and AX line, but I think within their respective lines, the cables are the same.
Best bet here.. Call Corsair. They will fix you up with the custom amount of cables you specifically need for your PSU, and be able to tell you what kind of cables you can plug into your PSU.
