Enermax Revolution 87+ 1000W Power Supply

As 2011 comes to a close, the power supply market is as competitive as ever. Platinum units are starting to show up more and more on the market, and companies are doing all they can to make their units be noticed. Enermax is one of those companies. Today, I’m looking at the latest iteration in their Revolution series, the 80 Plus Gold certified ERV1000EWT-G.

Enermax Revolution 87+ 1000W

Headliner. I challenge you to a game of horseshoes. A GAME OF… oh, wait. Wrong Arrested Development song.

As you can see by the picture above, it’s raining Revolution here at the site thanks to Enermax. Yes, I’m taking a look at the Revolution87+ 1000 watt model, to see what the latest in Revolutions is like. And you know what I just realized? I’ve tested an awful lot of 1000W models lately, most of them with right around the same load specs. Let’s see… we had that big Platinum Seasonic, and we had the XFX unit. Mustn’t forget the Thortech. And looking ahead, I have at least two more units with right around the same load specs: one of them an 80 Plus Gold like this one, and one of them an 80 Plus Platinum.

And with the load specs so close together, this is going to make comparisons easy. I’ve been asked to test at least one of these kilowatters in the exact same way I did the Seasonic Platinum, so why don’t I extend that courtesy to this Enermax unit and all the others, too?

Now, to be sure, I do have to make my tests run with test three at 50% load, so I won’t pattern things exactly like the Seasonic. Rather, I’ll use the XFX review as a model, because it’s the same platform. Fair enough?

Let’s check out some marketing.

Enermax Revolution 87+ 1000W

Wow. I thought the XFX box was crammed full of marketing. Here goes nothing:

Features

  • 87PLUS ready!
    Extreme efficiency PSU series with 87-93% efficiency @ 20-100% load. Certified to meet 80 PLUS® GOLD requirements.
    – Wait, 93%? That’s gotta be at 230V or something like that. I don’t think I’ve ever seen Platinum units hit that number yet. We’ll see what’s what on the next two pages.
  • ErP Lot 6 ready!
    Help system to meet ErP Lot 6 2013 (< 0.5W at standby mode) with high efficient +5Vsb circuitry.*
    * Required for ErP Lot 6 2013 compliant systems.
    – I remember when I parked in ErP lot 6. What they don’t tell you is that this one is across the highway in some farmer’s field. Took forever to get to the main gates. Wait, ErP stands for EuroPartyland, doesn’t it? Anyway, the place could have done without the constant Eurodance music being piped throughout. I mean, there’s only so much Vengaboys I can take without picking up a bazooka and saying, “The Vengabus is leaving. Now.”
  • C6 & Hybrid ready!
    Maximum compatibility with C6 & hybrid states of current and future CPU & GPU generations by ZERO LOAD design.
  • DXXI ready!
    100% 6+2P (8P) PCI-e connectors to support new generation DXXI graphics cards.
    – Say, will this leave us whistling DXXI? I hope so. The first part of this one reads like Enermax is trying to come up with a new math equation for solving how quickly newbies can be confused. Hey salesman! What’re all these P’s and percent things for?
  • EMC ready!
    Full-scale electromagnetic filtering protects your system against radiation interferences.
  • Future ready!
    12P modular design for possibly upcoming new CPU and GPU 10P and/or 12P connectors.
    – Hmm… Enermax has been riding this Vengabus for quite some time now. Back when I first saw this in the original Revolution units, I wondered whether the industry would change soon enough for this part of the marketing to matter. Since I’m sitting here more than two years later and the industry has yet to even show hints of moving to 10 and 12 pin CPU and GPU connectors, I’m thinking no… it doesn’t matter. Let’s worry about these connectors when they get here. That could take decades at this rate. It’s nice that Enermax is standardizing their modular connectors, but do they really need to?
  • SERVER ready!
    SSI PSDG support for latest Intel ® Core™ Extreme/i7/i5/i3, Xeon™ and AMD Opteron™ and SLI ® or CrossFireX™ and downward compatible with EPS 12V v2.92, v2.8.
  • GAMING ready!
    ATX12V v2.3 support for latest Intel® Core™ 2 Duo/Quad/Extreme/i7/i5, and AMD® Athlon™ 64X2 & Phenom™ II and CrossFireX™.
  • Stability ready!
    DC to DC converter design lowers energy loss for higher efficiency and better dynamic response and cross regulation.
    – I’m glad it’s ready for stability. That said, if it’s ready for stability like I’m ready for sanity we could be in a little trouble here.
  • CordGuard
    Fixing the AC cord tightly to avoid accidental shutdowns of your PC.
    – CordGuard, now with extra strength perspiration blocker, so you can feel fresh all day long.
  • HeatGuard
    Keeping PSU fan running for 30-60 seconds after shutdown to dissipate the remaining system heat and prolong system lifetime.
    – Like CordGuard, only scented.
  • SafeGuard
    Industry-leading multiple protection circuitry of OCP, OVP, DC UVP, OPP, OTP, SCP & SIP.
    – Like CordGuard and HeatGuard, but targeted at Adrian Monk.
  • SpeedGuard
    Advanced fuzzy logic fan speed control for optimal cooling and minimum noise. (Patented)
  • Twister fan inside!
    13.9cm pantented Twister-bearing fan with low noise and long lifetime. (100,000 hours MTBF)
    – Wait for just a second here. Who got pantented? That’s not very nice.
  • 100% 105°C Japanese electrolytic capacitors
    Highest component standards for maximum durability and stability.
  • Dynamic Hybrid Transformer Topology
    Technological breakthrough topology using a staged dynamic transformer array for extremely high efficiency with the most durable and stable output at any load.

Now, beneath all this is a bunch of charts and tables and stuff, but I’m just going to move on now. I could go on about the marketing, but I’ve probably already got the XFX marketing guys out for my blood. No need to compound the problem by involving the Enermax marketing department.

Enermax Revolution 87+ 1000W

Here we have a list of specifications and a chart of cables and connectors on all the different models.

Enermax Revolution 87+ 1000W

Opening the lid, we find that Enermax has not provided any padding at all for the unit. Not even a plastic bag for the power supply. In fact, if you look closely, you can see the outline of the power supply in the cardboard of the lid. I’d like to see them work on this a bit. We tend to like our power supplies to work when they come out of the box.

At least the finish on this one is rugged enough to resist scuffing from the cardboard, though.

And here we have the box contents: a power supply, 14 gauge power cord, modular cables with a bag, velcro cable ties, power cord retainer, case badge, screws, and manual.

The manual may be small, but it’s full of information.

The power supply is finished in the usual rugged Enermax finish we’re used to seeing in their Revolution models. The color scheme on this one doesn’t quite work for me, but it’s not terrible looking.

Another angle shows us the modular connectors.

The exhaust grille. You can see the tabs below the AC receptacle where the cord retainer clip goes.

And on the other side. No matter which way you mount this unit, your Revolution will always be on the up and up.

Here be the fan grille. Nice, translucent fan there.

Enermax Revolution 87+ 1000W

Wow. Except for the quad 12V rails, this spec table could almost be cut and paste from the two Seasonic based Platinum units. Combined 12V capacity is identical at 83A. Only the minor rails differ in ratings, but not by much.

And this is an example of what I was saying about properly designed 12V rail distribution in the XFX review. Enermax did good, here. At 30A each, the overcurrent protection is high enough that it’s not going to trip with most configurations, and yet it’s not so high that it’s useless. Like it or not, having single 12V rails as high as 83A in a computer power supply is a potential safety issue. You’re not supposed to weld with your power supply, but some of these single 12V units coming out today could almost do it. If you have a partial short in your rig, and the protection is set too high, will the unit shut down before the magic smoke appears?

A better look at the modular panel shows us a sticker that tells you exactly which 12V rails go to which connector. Nice… no need to even look at the manual for this data.

Speaking of modular stuff, here are the cables.

Enermax Revolution 87+ 1000W

And here are the hardwired cables. I would rather see the 8 pin EPS12V moved to the modular cables, to be honest. Not every rig needs a second such connector. I have no such problem with the two PCI-e cables. Chances are pretty good that if you need a power supply this big, you need both of those connectors too.
