EVGA SuperNOVA 750 P2 PSU Review

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Cross-Load Tests And Infrared Images

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 possible load combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V and 3.3V) as point zero.

Load Regulation Charts

Efficiency Chart

As you can see in the graph above, efficiency looks pretty good. Starting around 120W and nearly up to the PSU's full capacity, efficiency is higher than 90%, even with a significant load on the minor rails.

Infrared Images

We removed the PSU's top cover, along with its fan, and applied a moderate load for five minutes followed by full load for eight minutes. Right before we removed the load, we took some photos of the PSU's internals with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

With a 10A load on each of the minor rails and around 56A on the +12V rail, the only parts that get hot are the DC-DC converters' FETs responsible for generating the 5V and 3.3V rails. Energy losses are low thanks to the highly efficient platform. As a result, the thermal load is pretty low, so it doesn't prematurely wear the PSU's components even under intense stress.

    Thanks for the review Aris. I'd have to say that I'm very impressed with the performance of this unit, it is excellent. It is also nice to see that it has no issues with holdup times either.

    It was the P2 650 review on Tom's that helped me decide on buying that unit. Same as this, just 100 watts less powerful. Extremely happy with the stability and quiet operation. Very reliable units!

    Any Super Flower review should just read "It's Super Flower. Just buy it."

    Another great product from EVGA. I regret belittling EVGA with their early PSUs. I also mistakenly said, "I don't like that EVGA PSU"...

    With SuperFlower, they're known to bring greatness now. Anyone looking for "Good PSUs" should go straight to these units and buy them. Exceptional value with excellent performance. Sadly, they're still not available in my country.

    Right on. Unless you need significantly more or significantly less power, there's no reason to buy anything else.

    I like how EVGA has been stepping up their PSU game lately.
