Enermax is only 3 years I think, that's what the manual said when I got my Liberty a week back.

There were two main reasons I chose the 500W Liberty over the similarly priced Antec TP-II 500W. First the modular cables which were sleeved, and second, the high efficiency level of the Liberty.

If the Antec Neo HE was available, I'd probably have gotten that since the fan and modular cables are IMO better in that one.

But I think said bottomline is that you can't really go wrong performance wise if you're getting a brand like Enermax or Antec. But don't limit yourself, check out Silverstone, Zalman and Coolermaster as well.

you will appreciate Enermax if you encounter 1-2secs blackout
