Efficiency Testing:

  Efficiency testing was done using my trusty Seasonic power angel. It will test the Power Factor of this unit. What that means is it will tell us exactly how much of the power drawn from your wall socket is actually being used. The higher the percentage of the PFC, the better. Let's take a look at the whole scope of recent power supply reviews.
 

   The results of the Zalman ZM600-HP 600w were very good. Utilizing the newest technology in efficient power consumption, it's hard to ignore the stats compared to some of the other 'older' popular power supplies in the market especially when you consider it's size and rating. It produces good power and it doesn't waste it and that's a great thing.

   If you're like me and running at least one computer 24hrs a day/7days a week, you will seriously want to get a highly efficient power supply as soon as possible. Not only do they save you money in the long run, they also run more efficiently which means they run cleaner. That should equate to a nice long life also.
