Performance (40% of the final score) – let’s wrap things up with some scoring. This isn’t going to be a hard one… the performance of this thing was exemplary. We always had Gold efficiency, so no deductions will be made there. The same goes for voltage regulation, because we saw mythic level goodness at all times. Ripple control? No deduction there, either, because we were well into excellence there, too. The only deduction to be made, in fact, is with the continued so-so stuff in the power on spike tests, but this will only be half a point because there’s nothing really terrible about those, either. 9.5.

Functionality (20% of the final score) – this section goes the same way it did for big brother. We do have those in cable capacitors to deduct half a point for, but everything else gets a pass. I’d pull points over lack of accessories, but the software interface does make up for that again. 9.5.

Value (20% of the final score) – $119.99 gets you one of these at NewEgg right now. Only the Rosewill SilentNight fanless unit costs more money at this power level, otherwise the Seasonic Prime Ultra Platinum 550W unit is two dollars cheaper. Sorry, NZXT, but this is where the software interface making things more expensive does you no favors. I mean, you’re looking at $71.01 at the time of writing for the Seasonic Focus Plus 550W without the software control. There’s just not much value here. 6.

Build Quality (20% of the final score) – what can I say? There’s nothing at all to complain about, here. 10.

The 500 watt version of NXZT’s new E series of units has proven itself every bit the performer that its larger sibling is. And that’s very good for NZXT indeed. However, the super high price is a major obstacle when it comes to making this particular model a success in the marketplace. It’s competing with more powerful units with better efficiency, and there’s only so much value the software interface adds to things. It’s just not affordable enough to sell itself to me at this power level.


  • mythic level voltage regulation
  • long warranty
  • software interface
  • excellent ripple control
  • excellent build quality

The BAD:

  • high price


  • in cable capacitors
