Conclusion

Today we have taken our own initiative in purchasing a power supply in retail, from the world wide web. It was on sale for a great price, and we hadn’t reviewed an entry-level power supply from EVGA as of yet, and wanted to because it seemed like a good idea at the time.

We previously had great success using and testing the EVGA SuperNOVA 750 G5 750W power supply, which earned high praise from us, and our Gold Award. We know EVGA can make great power supplies. We, therefore, purchased the EVGA 750 N1 750W power supply and have given it our full review coverage today.

Today’s EVGA N1 750 could not be more different from the previous EVGA SuperNOVA 750 G5 that we reviewed if it had tried. Gone are all of the higher-end features that we found on that unit and we are left with a very barebones unit. The big question will be, did EVGA cut out too much with the N1 750? Let’s see.

Build Quality

The EVGA N1 750 starts things off on, well, the wrong foot frankly. The exterior represents a somewhat mixed approach with some decent touches (like the fan guard) and some lower-end ones (like the cables and sticker branding). The actual integration and construction on the unit is clean which is something that is always good to see.

The topology, however, is positively ancient these days and not up to modern standards. The component selection also features Teapo and CapXon standard electrolytics which the vibes those are giving us deep down in our stomach are the kind that follows a bad taco Tuesday (Ed: Your digestive issues are out of scope for this review!). Now, that said, there is a rifle bearing fan which is better than what we could see in a very entry-level unit so that part is good. The documentation with this unit is basically nothing and we basically get nothing on the warranty side (2-years) as well. Shocker there! Do I need the /sarcasm tag? (Ed: Enough with the shock jokes, we get it!).

Load Testing

The EVGA N1 750 started off testing very poorly and ended with a sizzle. We not only saw bad voltage regulation but a complete burnout of two units (more on that later). Voltage regulation was only measured over 0-75% load and even then we saw regulation of up to 0.29v on the 12v rail, 0.08v on the 5v rail, and 0.1v on the 3.3v rail. In addition to that, we saw efficiency that ranged from bad to babdder(er)(er), from 81.64% to 83.74% efficient at 120v AC input and 79.91% to 82.80% efficient at 100v AC input. So far then, the only reason the N1 750 would be shining bright like the SuperNOVA 750 G5 before it is because it may well be on fire at this very moment still.

DC Output Quality

The DC Output Quality results for the N1 750 were terrible. We saw peak ripple/noise values of ~85mV of ripple/noise on the 12v rail, ~30mV on the 5v rail, and ~70mV on the 3.3v rail. The kicker, that is just through 75% load and the 3.3v rail was out of specification in Test #2! This is more out of shape than me in a (Ed: Analogy censored). Yeah let that mental image marinate for a while.

Noise

I honestly can’t tell you anything about thing units sound profile during testing today. This thing was going sideways from the moment we started either unit and I was just trying to keep from having a literal dumpster fire on my hands. So, I guess I could say it is probably quieter than that sound in Dumb and Dumber.

Final Points

(Ed: Throughout this review, you may see references to multiple units. This is because we reached out to EVGA for a second unit for testing after the first one bit the dust and they kindly sent us another. Note that our test results were comparable with both units. You can read more about this adventure in our upcoming editorial to be linked here entitled “When Reviews Don’t Go As They Should”.)

The EVGA N1 750 is an excellent example of when mediocrity fails to live up to its own expectations. The EVGA 750 N1 started off with a build quality that was not great in any sense of the word. It was solidly mediocre. However, most people associate mediocre with, like, passing. However, this unit, in the end, failed to even make those low standards. The voltage regulation was not good but it could not even complete testing. The Transient Load Tests never happened because well, both units died. The DC Output Quality, while the units were running, was out of specification so that doesn’t even make the scoreboard. At the end of the day, this unit was just bad from end to end and users have no reason to consider this as a suitable product for any build we would look at in the enthusiast realm.

Though, I can say that the On/Off switch was well placed.
