Building a superior machine for a friend that's willing to spend money. What's are some of the top of the line power supplies (I'm looking at OCZ and Antec, anything specific within those companies?).

Thank you.

With these higher watt P/S's (500+ Watts), do you have to begin thinking about buying a case that supports better air flow due to the a greater amount of heat being produced?

The supplies will only produce as much power as needed, plus losses from efficiency, so they won't necessarily produce any more heat unless they are under heavy load. Since most computers get by on far less than 400w they should not produce any more heat than an equally efficient 400w supply, however these supplies do have a lot of overhead for extra hard drives, dual video cards etc.

Heat from the PSU shouldn't matter. All of these higher-end PSUs will utilize a mobo fan header to regulate PSU fan speed, and even a really crappy case would provide just enough air flow for the heat to be expelled out the rear.

Air flow concerns should be centered around the videocard and CPU (and in some cases, the hard drives).

PCP&C 850W For beeing able to handle highest load
Seasonic S-12 600W for beeing the most efficient and quiet.

What system are you going to make? no need to do an overkill if it's not needed.

definately the PCP&P 850w. it will cost like $500. are you getting like dual 7800's and an fx-57, and some vapochill lighspeeds for every chip that exists in the entire computer? :p

Yeah... you can spend like $800 on a rediculous PSU, but you probably don't need that.

Spec the rest of the system out, first, and then buy an appropriate, high-quality PSU.

PCP&C is the best, period. Even a 300-350W PCP&C will outperform an Antec or Enermax rated more than 100 watts higher. This is because their rating is valid for a much wider (and more realistic) temperature range.
