Performance (40% of the final score) – and lo, once more we get to do some scoring. This unit pretty well performed exactly the way I thought it would. The platform it’s based on isn’t new to us anymore, and has been incredibly consistent between models. Ripple control was excellent with all rails staying below the 25mV mark, so there will be no points coming off there. Efficiency conformed to 80 Plus Gold, so no deduction there. Voltage regulation easily hurdled the mythic mark with an average of 0.33% in the hot box, so no deduction there. But there will be a half point deduction once again for the power on spike suppression, where the 12V side of things continues to be a tad on the messy side. That means we’re doing a 9.5 here.

Functionality (20% of the final score) – what’s good for the other two models in the line is good for this one as well. Half a point comes off for the in cable capacitors, and there’s nothing I can find fault with anything else. 9.5.

Value (20% of the final score) – you’re looking at $148.46 to get one of these at NewEgg right now, and sadly this means the NZXT E series continues to be on the expensive side of things. A Prime 650W Platinum is almost twenty dollars cheaper. Prime Ultra Gold? Focus Plus Platinum? About thirty beans cheaper. RM650x? Focus Plus Gold? Almost sixty dollars cheaper. And look at the price of the 850W model. $159.49. Ridiculous. I like the software side of this unit, but nowhere near well enough to call this anything other than a below average value at best. This unit does even worse in this section than its little brother did. 3.5.

Build Quality (20% of the final score) – in no way do we have any issues here. The Seasonic factory knows their stuff. 10.

Now that we’ve seen the entirety of NZXT’s new E series, we know the whole range of units is outstanding. These things have amazing build quality, equally amazing performance, and the fact that they give you software monitoring and control only makes things better. With that said, the prices of these units across the board has been somewhat less than competitive, with this unit being the worst value of the lot. I mean, come on… the 850W model is only about ten dollars more money! Nobody’s going to want the software if it means shelling out another fifty plus dollars over a rival unit based on the same platform.


  • mythic voltage regulation
  • excellent build quality
  • excellent ripple control
