+12V Ripple


Wow. What more is there to say? The ripple suppression this power supply demonstrates is extremely good. The traces on our screen barely moved other than a small jump when things started getting hot and heavy in the Extreme test. You can really see where the load is coming from though as the ripple measured at the PCI-E connector is significantly more than that seen on the CPU connector.


+3.3V Ripple



+5V Ripple


As expected, due to the relatively low load on both these rails there really isn’t much to report here.

Temperatures & Acoustical Properties

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.

Conclusion

Conclusion


There is a lot to say about the Enermax Revolution 85+ 1050W but one line which sums things up perfectly: “Viva la Revolution!”. Aside from conjuring up images of a certain famous Che Guevara photo, that one line speaks volumes about what we think about this product. We expected great things from Enermax’s new line and let me tell you, it met most of those expectations while blowing the rest straight out of the water.

From the second you take the Revolution 85+ out of its box, you know that you are holding something special in your hands. Its durable exterior finish is quality personified considering it was nigh-on impossible to scratch and fingerprints disappear like they weren’t even there. Indeed, those red accents on the case really serve to add a certain “je ne sais quoi” to the whole exterior design. When it comes to cables and connectors, we really couldn’t ask for any more with the cables we all use on a daily basis being more than long enough to reach every part of most large cases.

Before this review we had been using the Corsair HX1000 as our gold standard to which we measured all other 1000W power supplies against but the Revolution changed all of that. When it comes to performance, other than a small slip in the +12V readings to the 8-pin PCI-E connector, Enermax’s poster child eclipsed the Corsair flagship again and again. However, we have to remember that our Corsair sample has seen over 1000 hours of use while the Revolution had run less than a tenth of that before the benchmarks were run. Could this have influenced the charts? Only time will tell as we stack both PSUs up against more competition in the months to come.

It is almost a shame that we have to interject some criticism into this love ballad but even Einstein needed to use an eraser to cover up a mistake every now and then. We feel that Enermax needs to take a serious look at their half-assed cable sleeving job and do it in a way that befits a power supply that retails for nearly $300. Having the multicolored mess of partially sleeved cables in an otherwise clean build will drive even the best of us to distraction. We would also like to see the warranty increased to reflect the growing trend among several of Enermax’s competitors to offer 5-year warranties. Three years is an awfully long time when it comes to computer components but for us; the longer the warranty the better. On the other hand, you know that when cable sleeving and a 3-year warranty are the only things our picky brains can find to bitch about, the company in question did one hell of a job.

Even though our new power supply reviews are still in their infancy, we can safely say that the Revolution 85+ 1050W is a giant among men. Granted, it did have a few very minor issues, but these were squashed under the landslide of positive aspects that this unit brings to the table. As such, it wins our Dam Good Award.


Pros:

- Excellent performance
- Quiet
- Stunning exterior design
- Good cable lengths and number of connectors
- Brilliant rail layout


Cons:

- Partially sleeved cables
- Price
- 3-year warranty




Thanks to Comtronic Canada for sending us this sample
