There's no way I'd ever shell out that kind of money for a PSU. I decided to go with a Silverstone 850W Zeus recently that has just as many amps (72A) and is rock solid. JonnyGuru rates it as one of the top 2 or 3 PSU's out right now. And I picked it up for $289.99.
I know that PCP&C is single-rail, but all their stuff is way overpriced. Even their tri-rail PSU's which have fewer amps than the Silverstones are 200-250$ more.
