I recommend the Corsair by far of my experience with the Antec PSU. However the best reliable and quiet PSU I have ever owned are the Thermaltake Toughpower Series, and also they maintain very efficient power, and covered by a 5 year warranty, and they are very quiet. I can never hear it over the case fans.
Depending on your needs the ToughPowers also have surge protection as industrial grade compacitors. There is a huge difference between the Pure Powers that are also very nice PSU which are 80% efficiant which cost less but the are only covered by a 1 year warranty.
The ToughPower Series at 87% efficacy are:
1. 1200W Model: W0156RU (which I have) down to a 850W Model: W0131RU
Also ToughPower Series also make models that are 85% effiancy:
a 600W Model: W0103RU, to 750W Model: W0116RU
