Introduction

We saw the first prototypes of the Pro82+ and Modu82+ series at CES, and we eagerly awaited our samples since then. At the following CeBIT in March, Enermax showed these two new series again but still we waited for our samples. After returning from CeBIT, we finally found our batch of PSUs at our doorstep and we started testing right away.

It wasn't too long ago that Enermax introduced the Infiniti series, which performed well in our testing, so we were quite excited to see how Enermax would top that performance. We heard from Enermax that these two new series would have performance equal to the Infiniti but at a cheaper price point. We initially thought these new power supplies used the basic Infiniti design, but we were told that this is not the case.



Enermax wouldn't be Enermax if they didn't include some new technologies in a new series. We will examine today what improvements Enermax made and how they function. We look at both new series today; they are essentially the same internally but play a different role on the outside. As the name suggests, the Modu series comes with modular cables. The Pro series doesn't have modular cables, which is the only difference between it and the Modu series.

Enermax was one of first companies to begin selling retail power supply several years ago. They are one of the oldest companies in this field, with several inventions to their credit during this time. According to the company, Enermax was the first to offer a colored power supply, and they were the first to provide an external fan speed controller. We don't know for sure if that's really true, and we can't say that colored PSUs is really that revolutionary, but Enermax does seem to be at the forefront of new PSU innovations, and they rank in the top five in terms of sales.

Their trend of staying ahead in the market place continues, with some very competitive power supplies in their two new series.

    Horizontal bar charts for price? Really? I guess when all you have is a hammer... Reply

    Well put...

    One of the shoddier reviews I've seen on Anandtech for quite some time, including some shocking graph abuse and grammatical errors throughout.

    In the DC Output Stability and Quality section, There are four PSUs in the top three graphs and then only three shown in the analysis below. Which 525W supply is that?

    In the graphs below, I assume the numbers at the lower half of the nonsensical Y-axis are meant to be negative? And is the load percentage on the X-axis a percentage of total rated PSU capacity, or rated line current. And in either case, are other lines loaded and if so how? You'd expect completely different 12v load characteristics depending on which other lines are loaded any how much.

    "In case of ripple and noise, we were surprised to see very little distortion on the rails. The highest amount of ripple on the 12V rail was 16mV for example. The other rails were similar except the 5Vsb rail, which went a little high. That's pretty common, unfortunately."

    Why is that surprising? How did you measure ripple? Is that amplitude or peak above rated? A little high under what circumstances? Why's that common, and if it's only the 5V Standby Rail, why is that necessarily unfortunate? The whole article is full of meaningless generalisations like that one...

    Anandtech has enough quality writers not to need filler like this. All in all, D-

    Apart from the upgrade in caps, there seems to be no design improvements. On the contrary, the workmanship looks a bit dodgy. I'd wait to see if these blow up left right and center after a year of use before passing a verdict.


    [quote]To our surprise, there are two main capacitors, which is something we don't see often in Enermax power supplies.[/quote]


    Whaaaaa??? Last I checked the entire FMA lineup had "two capacitors" on the primary side.

    At the beginning of the section on the Pro82+, you state, "The package is quite different from the Modu82+ series and comes in completely different dimensions". I think that you were just describing the dimensions of the box that the power supplies come in, but the picture at the start of the article, where the power supplies are stacked on each other, gives the impression that the power supplies themselves might be of different dimensions.

    Can you confirm that the external dimensions are the same for all these new models? Are these power supplies of the typical size?

    Thanks.

    Yes, only the package is different. Reply

    Your photo of the label for the big Pro82+ shows 625W, but your charts on pages 12 and 14 say Pro82+ 525W. Which was it actually?

    Didn't look elsewhere, but these are on Newegg right now for $10-30 more than you list in the review. The Infiniti 650 is priced the same as the Modu82+ 625W but the Infiniti ships free, and the Infiniti 720W is cheaper than either after a $25 MIR.

    Any good reason (like you couldnt get ahold of one) for not including the 425W PSU of this line? Its by far the most reasonable of the three... too bad. Reply
