Does anyone have any experience of Abit KN9 main board working with AMD 7850 (AD785ZWCJ2BGH). Officially is not supported, but I wonder if latest BIOS may make it work?

In all likelihood, it will work fine. AM2+ CPUs generally work fine in AM2 mobos. Just make sure you flash your BIOS to the most recent version BEFORE you install the new CPU.

Good luck!

Is this a new CPU or a used CPU?

brand new

I also thought it could be lack of power, but when disconnected CD, flopp still wont up. Anyway I don't think it could be such a big difference between Ahtlon 3200+ and the new one in terms of power consumption...

Not a power issue. Could just be that your mobo doesn't work with the 7850. I have 2 AM2+ procs in systems where they are not on the CPU compatibility list and have have no problems. With the older mobo, your only options are a newer mobo or return the CPU for one compatible with your rig.

I have oher question.
Highest supportd by m mobo model is 6400+. 6400+ black edition is not listed, but they listed 5000+ and 5000+ black edition as seperat models.

This is confusing because it suggest that 6400+ black may be not supported, however there are no deifferences between 6400+ and 6400+ black in terms of technology apart from that it is unlocked and easy to tweak... Tell me if I am wrong?

The 6400+ and the 6400+BE are the same CPU as far as your mobo is concerned. The difference in the BE being unlocked (for easier overclocking).
