just had a EM liberty 620 die myself one month of use. had a 500w die in a customers machine after 3 months a 400W after 6 months.

I purchased my first EM PS about the time they released the NF2 chipset. it ran for 3 years before i sold it on the forums.

I just started buying EM libertys the past 8 months, there track record sofar is terriable this time around.
