[Lobarev Eugene] "U see, that KONA 3G work on PPC G5 LATE)) "
That was a fairly rare machine, you are correct the card will work in that machine- However You will be only able to handle Uncompressed and maybe DVCProHD, you will not be able to playback many of the ProRes flavors, AVCHD or some R3D on that computer without an intel processor.
" But I see on monitor from composite or HDMI only noise. "
How are you watching Composite Video- the K3G only has Component, HDMI and HDSDI V-outs.
Did you re-flash the firmware?
you are going back generations in hardware , and the newer firmware will not work with older versions, your bigger issue is that most of the tools you need to read and playback RED content will not run on a PPC machine.
ProRes HQ will have limited ouptut success on A PPC machine, and the Min specs for FCP7 require Intel processor.
So it "may" work- my guess is more hassle than anything
