ac power to system

I am preparing to upgrade my system. The speakers are Thiel CS6, everything else will be new. I know I need a high wattage amp. I am not able to run a separate power line to the ac outlet.
Without going crazy, what do I need to get to ensure I have stable and sufficient power supply? What should I budget?
I am guessing the amp, preamp, and C/D player will be about $18,000 used/demo.
Thanks.
