External Appearance


The new series from Enermax surprised us as we had imagine something completely different (thinking back to Computex from last year). At that time both series were equipped with a 12mm Magma fan and had a very rough sandblasted paint scheme. Enermax has returned to a more traditional look and we think the change was only for the better. In an effort to reduce costs Enermax had to keep painting to a minimum which is why these units now only come with simple black paint. On the other hand, not all the changes were an effort to reduce costs; an expensive feature for example is the 139mm shiny golden fan. It fits quite well with the design aesthetic actually and makes this new design look better than the previous one with the red Magma fan. There is one little detail that doesn't quite fit, however: the Enermax logo in the middle of the fan guard looks a little odd with the square shape over a circular fan. As always, beauty is in the eye of the beholder.

The Modu87+ power supplies have the cable management jacks at the front of the unit. There are five jacks with five pins and two with twelve. The jacks have the same size and shape as on other Enermax power supplies, and since the company offers separate cables in retail packages you can use old cables even if you want to switch to a new Enermax unit. Above the usual main switch and AC input you will find a small area with a note saying "Please put ENERMAX log sticker here." You can find the Enermax sticker in the package, but why bother? Enermax explained the reason for not attaching it in the factory is that the company doesn't know what direction the user is going to mount the power supply, since various cases have the PSU at the bottom and others have it at the top. If they pre-apply the sticker, it would be upside-down for some users. If you want your system to be "just so" after assembly, this might be an important consideration.

The CordGuard

Below the AC inlet and main switch you will find something new. These two hooks belong to the newly acquired patent from Zippy and now offered by Enermax called CordGuard.


The CordGuard is nothing more than a small wire-hook attached to the power supply. Once you connect the power cord you can lift the hook up to securely fasten the cable. This makes sense in households where you have the PC standing in an open space and someone could accidently pull out the cable. It might not be a critical feature for everyone, but it will undoubtedly come in handy for some users. Enermax will be modifying all of their PSUs to include the CordGuard function going forward, but we really don't think this is necessary.

Enermax posted this video on YouTube to show real life experiences and how they could be solved with CordGuard. We think it's dangerous to let kids play behind a PC in the first place, and let's just hope they don't notice the power switch….

    simple, to the point, should be done more. Reply

    Where do you get the Enermax Modu 87+ 500W? I can only find the 700W on New Egg, and can barely find the 600W flavor. Have these items been released yet? If not, when is the expected release date? Reply

    I would be really interested to see how this compares to another PSU from Germany, the Nesteq ASM X-Zero 500 semi-passive. Reply

    Really nice PSUs, but a bit shame they come with three 12V rails instead of one "big one" Reply

    To be brutally honest here, I would be very surprised to find more than one person in the pool of hardware geeks that are my friends that has a computer that, even under load, consumes more than 300W. Even really powerful gaming machines (say, core i7 + HD5870) usually draws around about 100W idle, and with recent developments usually even less than 80W (yes, really). Under load, these machines barely top 200W. You would need to do some serious skulltrailing to build something that needs 400 or 500W.

    For the serious gamer, a 350W PSU should be the norm - why you ask me? At idle, a single-processor, single-gpu machine uses about 20% of the PSU's rating, and that is where the serious efficiency benefit is for forward converter topologies. Right now, gamers use ridiculous 500+ W power supplies which leaves the PSU uselessly wasting energy at idle, where the computer is most of the time anyway.

    This is by the way also one of the humongous errors made by various reviewers (not anandtech by the way) - they for instance try to test a C2D E5200 (extremely power-efficient) but decide to run it in their usual test bench which inevitably contains a power supply designed for overclocking. Then they're surprised that the E5200 seems to be no more efficient than a Q9600 or something, but in reality the E5200 system consumes so little that the PSU is hopelessly inefficient at that point. If you use this knowledge you can build machines that idle below 35W by just and only using a very low-wattage power supply (barring the truly high-end video cards of course)

    I'll agree with you to an extent. The 700+ PSU's are more than overkill for most people. But keep in mind the longevity of the PSU. Most people do not like their PSU's running 80% of capacity when under load, and I constantly hear 60% as the sweet spot for long-life. We are now approaching a sort of saturation point for PSU efficiency so I don't see people buying a new PSU every single time they upgrade or rebuild. It was different when we were jumping from 50-60-70% efficiency. But going from 80-82-84-etc is not really that big (from both a utility cost and heat standpoint).

    These new PSU's are great in that they get very high efficiencies at anything pretty much above 20%. Other brands are also almost there (25-30%), so it's kind of moot. You're not going to see large price differences if they made 350 or 400w because the main cost is in design and manufacturing, not so much the difference between parts (some but not the bulk of the cost).

    Check out the street prices, the MSRP of the Modu87+ was 150€ and it's now already at 116€...

    "Enermax posted this video on YouTube to show real life experiences and how they could be solved with CordGuard. We think it's dangerous to let kids play behind a PC in the first place, and let's just hope they don't notice the power switch…."

    Or do one of the more creative/inventive things kids have been known to do. Like perhaps try to stuff a peanut butter and jelly sandwich through the fan grill . . .

    But right, I do not think any responsible parent is going to let their young kids play around with the power supply of a computer in the first place. I would think Enermax needs to work on their marketing a bit more . . . The video stinks, and screams "skiddy". CordGuard is not a terrible idea, but come on. Are they really trying to market a $.05 gimmick ? When did the name Enermax sink so low ?

    Personally, I would like to see some aircraft quality (screw-on ) connectors for the removable power connections, and a plain black fan would be perfectly fine with me. Also, I agree that the name badge on the fan guard is not necessary. Yes, I *would* pay more ( fair price ) for the above mentioned connectors.

    Why is 115VAC so inefficient in comparison to 230VAC? Reply

    I can see the appeal, but for me a single 12v rail over 50a is ideal, rather than 3-4 rails. Reply
