The Antec PSU's failures were more due to design flaws than poor manufacturing. They used low temperature caps to save money, but used slow speed fans to reduce noise. The low speed fans increased the temperature in the unit, which in turn made the caps exceed their useful temperature range, which in turn caused the caps to fail resulting in a puff of black smoke.
Antec was new to the PSU business at the time, so mistakes like this were to be expected. It isn't surprising that they refocused on their design and have better quality now, since the failures of the past are a good motivator. It just sounds funny to me when I hear they have high quality PSU's, because the PSU's I used from them in the past had major problems. Logically it makes sense, but I still am gunshy about buying another Antec power supply.
