The 9800GTX would consume less than the 9800GX2, as for PSU requirements that are often printed, they are highly exaggerated. You'll be fine with 1.

Should work, since the 9800GX2 requires a 580W PSU. So you should be fine.

That 550W is referred to a loaded rig with 9800GX2. 9800GTX is less power compared to 9800GX2. Your PSU should make the cut.

As long as a card requires only one 6-pin, any good quality single 6-pin PSU should work fine.

Will EASILY work. The 9800GTX is nothing more than a G92 8800GTS with a more efficient power system and the ability to run tri-SLI

It depends on how many Amps are being supplied through the 12V Rail(s).

I don't know exactly what the 12V Rail requirement is for 9800GTX's in SLI. This link may provide some useful information on SLI capable PSU's though. EDIT: That links kind of old (2005), sorry. I'll keep looking.

Hopefully someone else will chime in with more answers for you.
