I have had 2 Enermax PSUs die in the past 3 years. One was 3 years old, the other was 2. I am looking to upsize my current PSU for my main unit from 431 to 500 Watts. Any idea of the AX500-A (http://www.newegg.com/Product/Product.asp?Item=N82E16817104934) by the FSP Group is any good? I have an Abit NFS-7 2.0 motherboard. Thanks.
