SLI Efficiency Testing


Well, there you have it. Without a doubt the Enermax Pro82+ is quite an efficiency power supply since it was able to trade blows with two other 80Plus certified power supplies without any problems. Efficiency does tend to fluctuate a bit but that is only normal with non-linear loads generated by the tests we run. However, it is great to see that Enermax is able to make good on their claim of an efficient product.

Voltage Regulation Testing

A Note About +5V and +3.3V Regulation

While both the +5V and the +3.3V rails were monitored, our present test system puts so little load on each of these rails that we are not going to bother posting the charts. This practice has been going on since we started 400W to 700W power supply testing on the present test system but with our upcoming revised system we will begin showing these charts like we do in the 700W and higher power supply reviews.

That being said, the Enermax’s +5V and +3.3V rails performed as every other power supply we have ever put through these test did: it passed with flying colors.


+12V Regulation



In the realm of power supplies, +12V performance is key and this power supply has that performance in spades. While it is not quite as stable as the other two power supplies we put it up against, we were nonetheless extremely pleased with the results it achieved.
