For value the Corsair TX-750
has a 60Amp single +12v rail, retails for $160-$180AUD, so should be decent over there too. Best PSU in its price range for sure.
For high end I also like the 1000w+ Thermaltake toughpowers, not usually a fan of Thermaltake but these are good PSU's! Or the Silverstone DA1200, which has a single 90A 12v rail and is better value for your money.
