i have recently bought the thermaltake toughpower 600w and it's working perfectly, although the antec truepower trio 650w was the one i was originally looking at buying.

Antec Truepower
Newegg.com - Antec True Power Trio TP3-650 ATX12V 650W Power Supply with Three 12V Rails 100 - 240 V UL, CUL, FCC, TUV, CE, C-tick, CCC, CB - Retail

Thermaltake Toughpower
Newegg.com - Thermaltake toughpower W0103RU ATX12V / EPS12V 600W Power Supply 100 - 240 V CE, CB, TUV, FCC, UL, CUL, and BSMI certified - Retail

for the toughpower one of the 'cons' listed says that it is gathering some heat, but mines running at about 15-25c atm so i dont think it's an issue if you have a good case.

antec truepower 650wattt.. works a treat, exceptionally quiet and havent heard cpu fan dimm once.. great buy at only 170$ aud as well.
