Conclusion

The EVGA SuperNOVA 750 G5 is the first power supply we have seen here at TheFPSReview from EVGA. However, EVGA has been marketing power supplies for a while now even though most users may still think of GPUs first when they hear the EVGA name. However, the EVGA SuperNOVA 750 G5 80 plus gold 750w fully modular power supply we have here today is just one of a long list of power supplies that EVGA has produced when they decided to start selling PSUs, as they dove headfirst into the market with a full range of products. The SuperNOVA 750 G5 is not their highest-end product, but it is situated right in the heart of the PSU market making it one that lots of users will look at. The question is; when they look at this SuperNOVA are those users blinded by the light or looking into a great void? Let’s see.

Build Quality

Today’s SuperNOVA 750 G5 starts things off with a build quality that is very good for its market position. The exterior represents a somewhat mixed approach with some very high-end 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 very clean which is something that is always good to see. The component selection features Nippon Chemi-con and Rubycon standard electrolytics paired with Chemi-con solid capacitors. There is also an FDB fan today which will be of interest to our quiet cooling enthusiasts out there. The documentation with this unit is not terrible, but it is also not the best. The 10-year warranty is an excellent length though and many users look for such things.

Load Testing

Today’s SuperNOVA 750 G5 started off testing in excellent shape. We saw voltage regulation of up to 0.04v on the 12v rail, 0.04v on the 5v rail, and 0.04v on the 3.3v rail. In addition to that, we saw efficiency that ranged from 88.65% to 91.52% efficient at 120v AC input and 86.81% to 90.39% at 100v AC input. These numbers are excellent, and this unit is a bit more of a mainstream offering, so these values definitely get a bit of a bump because of that. Now, in a relative sense, the only other 750W product we have reviewed to date is the Phanteks AMP 750 and this unit did best that unit in this portion of testing. So far then, the SuperNOVA 750 G5 is shining bright!

When we look at the Transient Load Tests results for the SuperNOVA 750 G5, we see that the results are very good. When directly loaded, the 12v rail showed a peak change of ~390mV, and the 5v rail had a peak change of ~40mV. During the 12v load, the unloaded 5v rail saw a peak change of ~30mV. In absolute terms, these results on the minor rails are excellent, but the 12v results are not quite as impressive. In relative terms, this unit was mixed with the Phanteks AMP 750 because of the not quite stellar 12v rail. So, this unit did well in this portion of testing but it is not quite the best of the best in this aspect.

Noise

Today’s EVGA SuperNOVA 750 G5 is not a tiny capacity unit, but it is efficient and it comes with a FDB fan (which quiet cooling enthusiasts just go ga-ga over). That all said, this was not the quietest unit we have ever had in for testing. In fact, it was audible in our load testing environment at 50% load and up. This easily puts it behind the Phanteks AMP 750 we reviewed. For quiet cooling enthusiasts, this power supply is probably not going to be your best due to these factors. However, users who can stand a bit more noise will probably find that the unit is well behaved most of the time as they will be using less than 50% power. Plus, you probably won’t be trying to bake your PSU to death like we are trying to do.

Final Points

The EVGA SuperNOVA 750 G5 is an excellent unit with high performance and high efficiency in the mainstream marketplace. The SuperNOVA 750 G5 gave us very good/excellent build quality, excellent voltage regulation, excellent DC Output Quality, and good Transient Load results. The one downside we found was it is a bit louder than other options we have reviewed to date. So, what is this unit going to cost us?

Today, we find that the SuperNOVA 750 G5 is currently harder to come by, like all units, and the best price we can find is $139.99 from Newegg Business or $179.99 from Newegg and Amazon. Now, that is a bit of a tough price to swallow since it is coming in above where the market used to be (especially that $179.99 number)! However, it seems every power supply is coming in higher than it used to these days. Well, that is, if you can find them in stock. So, we cannot fault EVGA for that. Thus, this unit is going to be an excellent value at its normal price and still a value today simply because the market is all out of whack.

Users looking for an excellent mainstream power supply with a long warranty need not look any farther than the EVGA SuperNOVA 750 G5 because, in the end, it does shine bright today!
