Specifications
This was a difficult section for me to write. "Where do I
start?" " What info should I include?" "What is too much?" "How can I write
this review so it doesn't sound the same as my last power supply review?" These
were all questions swimming in my head as I embarked on this journey. The inner
turmoil was almost unbearable. I think I have a handle on it now. You can
assume that this power supply has the same raw power and basic features as just
about any other power supply in its class. But, if you take a close look at
some of the additional safeguards and tight tolerances Enermax uses for their
power supplies you'll find that this is truly a gem. These power supplies are
some of the best constructed power supplies on the market right now. They are
extremely well made with only the highest quality components which will provide
your computer with clean and consistent power. I'm going to share some of the
specs that should be the very basic criteria for selecting a power supply. But,
for those of you who are more technical minded and have a passion for details
I've included the spec sheets that Enermax provided
here. Here's some basic specs for you to ponder:
