As you can see by the picture above, I have the latest and greatest design from Enermax in my hands today, the Revolution 85+. This design promises high power at extremely high efficiency, something that is not always easy to do. My review sample weighs in at 1050W, making it the second most powerful of the four Revolution models, with only the 1250W model above it.

The 85+ in the name seems to suggest what the folks at 80 Plus have found factual - this unit is supposed to start at 85% efficiency and go no lower than that in normal operation. It will be very interesting indeed to get this unit on the load tester to see what happens there. Meantime, we're going to wade through the waters of the usual box and product shots first.

You've seen the front of the box, so now I'd like to introduce you to the back of the box. Box, readers. Readers, box.

As is the usual case, there's a fair bit of marketing hype to be found. Up in the top left corner, there's an efficiency diagram that promises an astounding 91% number at 50% load at 230VAC input. While I would dearly love to put this claim to the test, I'm in Canada. So, I'll have to go by the 115VAC curve and be content with a mere 88.6% number. That's still a pretty lofty number, though, so I'm looking forward to seeing if the unit can really do that here in the lab.

Below the efficiency diagram, there's another efficiency table, which looks to tell you how much money you'll save if you use this unit instead of the not so efficient competition.

Finally, in the bottom left corner there are a bunch of fancy diagrams. Just like we saw with the Liberty Eco 620W, one of the diagrams promises future readiness in case somebody revises connector specs. Another diagram explains that six 12V rails means perfect load distribution. We'll see about that, Mr. Diagram. Still other diagrams brag about SSI compliance and zero load requirements.

You're probably wondering what those bullet points on the right say. Here's a close-up:

And because my hands are cold, I'll type them all out too just so I can warm up:

  • 85PLUS ready!
    World's first PSU series with 85-91% efficiency @ 20-100% load. Certified by 80 PLUS® organization (850/950/ 1050W).
    -world's first? I don't know if that's entirely accurate, but it's very impressive all the same if the 91% number is true.
  • FUTURE CPU ready!
    Ready for most upcoming CPU generations by 12P sockets for possible connector changes, by complying to latest EPS12V PSU design guides for compatibility & by ZERO LOAD Design for C6 state functions.
    -is there a dress code for these C6 state functions? Because I gotta be honest, I keep getting thrown out of those things around here.
  • FUTURE GPU ready!
    Ready for most upcoming CPU generations by 12P sockets for possible connector changes,by six massive 12V rails for perfect load distribution & by ZERO LOAD Design for Hybrid Mode functions.
    -they sure are proud of that ZERO LOAD thing, yes? This is already a good indicator of independent voltage regulation. The load testing voltage readings should be stable indeed.
  • 24/7 @ 50°C ready!
    Non-Stop industrial class performance at 50°C/122°F ambient.
    -the hot box should be getting that warm, if not warmer
  • 99% 12V Power
    World's first EPS12V PSU with 99% 12V output capability.
    -this seems to suggest that Enermax is using the DC-DC conversion method to derive the 3.3V/5V rails from the 12V output.
  • SERVER ready!
    SSI PSDG 2009 support for latest Intel™ Core Extreme/i7, Xeon™ and AMD® Opteron™ and SLI™ or CrossFireX™ and AMD GAME! or AMD GAME! Ultra systems and downward compatible with SSI PSDG 2008 1.0, EPS12V 2.92, 2.91, 2.8.
    -a healthy dose of techno babble proclaims that this unit is compatible with, well, every server you could plug it into.
  • EMC ready!
    Full-scale electromagnetic filtering protects your system against radiation interferences (CE EMC EN61204 compliance).
    -wait, wait, wait... radiation? There's no... plutonium in here, is there? Gulp. Oh wait, they mean electromagnetic radiation. That's better.
  • HeatGuard
    Keeping PSU fan running for 30-60 seconds after shut down to dissipate the remaining system heat and prolong system lifetime.
  • PowerGuard
    PSU status monitor with 4-mode LED (Off / Stand-by / OK / Fail).
  • SafeGuard
    Industry-leading octuple protection circuitry (OCP, OVP, AC UVP, DC UVP, OPP, OTP, SIP)
    -SIP? I think they mean SCP, actually, or short circuit protection. Although, Silly Imagination Protection might be of some use to units in this lab, too. The rest of the acronyms stand for overcurrent protection, overvoltage protection, AC undervoltage protection, DC undervoltage protection, overpower protection, and overtemperature protection.

Moving on to the sides of the box, we see a chart with the various cable and connector counts...

...as well as a set of load tables for all models in the Revolution 85+ lineup. Man... 104A combined 12V for the 1250W model. No wonder that one hasn't been approved for North America... it's too powerful. The 1050W, which is as high as it goes for us North American residents, tops out at 87A combined at 12V. That's still a really nice number.

My eagerness to feast my eyes upon the majesty of the Revolution 85+ was thwarted momentarily when I opened up the box and saw two more boxes, along with the user guide and a folding modular cable pouch.

But I wasn't thwarted for long, as you can see here. In all, the Revolution 1050W comes with a user guide, cable pouch, modular cables, and six velcro straps.

Here's the user guide. While thick, it only has a few pages of useful info, repeated in eleven languages. Despite this, it tells you pretty much everything you need to know about the unit right down to which connectors are on which 12V rail.

The Revolution presents a striking image here with its fancy matte gray appearance and red accents over the fan. I don't know if it's entirely my cup of tea, but I have to admit it stands out from the crowd.

About the only thing I have to complain about appearance-wise is the orange color of the medallion over the fan hub. T'would have been better in my opinion if it were the same color as the red fan border. But that's a minor complaint. Peek-a-boo, ATX connector, I see you!

You may be wondering which of those modular cable connectors are on which 12V rail. Well, I'll tell you. First, the black connectors, which handle the SATA and Molex chains. The top three connectors in the picture are 12V4, while the bottom three are 12V6. Moving over to the red connectors, from top to bottom, we have 12V4, 12V5, 12V5, and 12V6. And what are all these 12V rails rated at? Take a look at the picture below.

Yes indeed, all six 12V rails are rated at 30A. That's plenty of current capacity for literally anything I can think of. Nothing is going to shut those down, unless you decide to try and power a TEC off this thing. And even then I can think of ways to mod this thing to handle that. Thirty hard drives? No problem, there are two 12V rails you can plug into. Three 295's? No problem, just put one card each on its own 12V rail. You're upgrading straight from a 5V based Athlon XP rig and want to get the PSU first? Well, even that's not a problem, for the combined capacity of the 3.3V/5V rails is up at 170W, more than enough for that old A7N8X.

In this here tentacle shot, we see a weird little black and white cable coming out of the unit. That's a good old fashioned fan monitoring cable, just like older Antec units used to have. Just in case you want to be assured at all times that the PSU fan is spinning. Not a bad thing to include, methinks.

As you can see, the sleeving is that same treatment we saw with the Liberty Eco. It's like a snake and Grandma's old Hoover had a baby or something. Fortunately, unlike the Eco, the sleeving is much tidier. No ending the sleeving twenty feet away from the connectors on this unit.

8-pin EPS12V connector (590mm) 2* 12V1/12V2

Unit Dimensions(L x W x H)
190mm x 150mm x 86mm

Zounds! Not only does this power supply come with 6 Molex connectors, it also has the cabling for 16 SATA devices divided between four cables. Those aren't going to be easy to use up, though I'm sure there are people reading this who will be glad to give it a try. To them I say "go nuts," for this unit does have the juice to handle whatever you throw at it.

Speaking of juice, how about joining me on the next page, and we'll see just how much juice we can get out of this bad boy, shall we?
