Performance (40% of the final score) - as it turns out, my long wait for an Enermax unit was, for the most part, worth it. Voltage regulation was very good, efficiency was very good, fan noise was nonexistent, and the ripple and noise suppression was downright awesome. Now that the tan glue of death is gone, there simply is no reason to avoid this unit for anything performance wise. I do feel that the voltage regulation could be just a bit tighter though, and I'm still laughing at the useless loose PFC coil zip tie mount, so I'll pull a half point for them and toss out a 9.5.

Functionality (20% of the final score) - I'm finding the Enermax to be a little bit of a mixed bag here. I like the one modular cable that combines Molexes and SATA connectors. I don't like the halfhearted sleeving on the hardwired cables. I like the little arrows on the modular cable connectors that tell you which way to plug them in. And I guess I sort of like the four 6+2 pin PCI-E cables, even though I'm not sure there's much call for four of them on a unit only good for 620W. 8.5.

Value (30% of the final score) - the lowest price I can find is $120.99 over at That puts it right into competition with the Corsair HX620. And considering the level of performance you'll be getting with this unit, it looks like the decision is going to be a hard one for anyone looking at a performance modular in this class. 10.

Aesthetics (10% of the final score) - what works for me is the usual sleek matte black treatment. The gold fan grille goes along with it nicely. But the Kirby vacuum style sleeving on the hardwired cables just sticks in my craw with the way it stops a country mile from the PCI-E and EPS12V connectors. Two points off for that. 8.









Total Score



My first Enermax turned out to be a unit that is sure to please anyone out there looking for a good midrange modular unit. It's very stable, very efficient, and provides extremely clean power at the outputs. There are a couple of things I think Enermax needs to look into yet, like the ineffective zip tie mount on the PFC coil, but really I don't see any reason why you shouldn't just go ahead and buy one right now. Go forth and spend, loyal readers!

The Good:

  • very efficient
  • very stable regulation
  • no tan glue of death
  • lots of SATA connectors
  • very quiet
  • kept working at full power well above 40 degrees

The Bad:

  • 76 degrees and no overtemp shutdown

The Mediocre:

  • loose zip tie mount on the PFC coil... c'mon, if you're going to brag about this, at least make sure that screw has threadlocker on it, otherwise just use glue like everyone else
