Page 6 - Scoring

Performance (40% of the final score) - it's time to do the scoring stuff. This unit was, just like little brother, much better performing than I expected. Voltage regulation was an excellent 0.53% in the hot box, just a hair short of mythic. Efficiency didn't just meet Bronze, it passed Silver level too. Ripple control was fantastic, with even the 12V rail nearly going below the 10mV mark. Finally, the S&C point is safe from me because this unit cleared that hurdle as well. 9.5.

Functionality (20% of the final score) - I have but two deductions to make here. No, wait... three. First, the same half point comes off for documentation I pulled on the 750W model. Next, half a point drops off for the single CPU cable. Third, I have to dock a half point for the in cable capacitors. Teapo or not, they interfere with cable management so I have to complain about them. All else is fine with this unit, and I particularly like the not so low end features like switchable fan modes. While Bronze level used to mean high end units, recent efficiency improvements made companies not care so much about adding such things to Bronze units, which is now seen as bargain basement. I like this. 8.5.

Value (20% of the final score) - Newegg's asking $109.99 for this unit right now. And that would be a solid price... if Seasonic's Focus Plus weren't right there at the same price eating this unit's lunch. And then there's the Thermaltake Smart Pro RGB fanned fully modular 850W for ten bucks less money. Now, I'd still take this one over that Thermaltake, but as long as Seasonic is sitting right there, I don't see much reason to get this unit. 7.

Build Quality (20% of the final score) - no issues to speak of, except for the fan quality. And because the warranty is decent, I'll be letting it keep the fan point. 10.

Total Score



The B3 850W proves once again that EVGA is serious about giving us good power supplies. However, at 850 watts, this unit is just missing the mark when it comes to actually competing in the marketplace. It's a good power supply, but it's up against too strong competition at the price point it's sitting at. The current $20 rebate makes it worth it, however... as long as you're the type of guy or gal who is willing to deal with that hassle.

The Good:

  • near mythic voltage regulation
  • Silver efficiency
  • semi-fanless mode switch
  • fully modular
  • amazing ripple control

The Bad:

  • should really have a second CPU cable

The Mediocre:

  • fan quality is questionable
  • in cable capacitors
