Enermax Revolution 85+ 1050W Power Supply Review

Temperatures & Acoustical Properties

Temperatures


Through higher efficiency comes less power lost to heat and the Revolution demonstrates that quite well. Even though it seems to present slightly higher idle exhaust temperatures than the HX1000, the Revolution reigned things in to handily win the contest. Let me tell you, a delta of 4°C may not look like much on paper but when it comes to your system dumping hot air into your room, it makes a hell of a difference.


Acoustical Properties

Considering the hellish, ear-drum shaking amount of noise that comes from our test system’s two HD 4870X2 cards and the dual Panaflo monster fans on the CoolIT Boreas, it is a miracle I haven’t gone deaf. As you can imagine, this setup isn’t the best for proper acoustical testing but by placing my ear next to the unit, I was able to get a pretty good approximation of the noise it produces.

Even though the fan on the Revolution 85+ spins up quite a bit when running the higher wattage tests, it never becomes loud or annoying. From what I could tell, bearing noise is kept to a bare minimum and other than a muted hum; most people won’t even know that the fan on this unit is running. It also seems like Enermax’s Air Guard around the fan’s periphery almost completely eliminates the usual “whoosh” we have come to expect from fans operating in a closed environment.

Something else that should be mentioned is the fact that the fan controller will keep the fan spinning after the unit shuts down to dissipate any left-over heat.
