Enermax Launches the Pro82+ and Modu82+

Modu82+ Package and Appearance
The power supply comes in a very nice color box with all the necessary information on it. The unit is encased in bubble wrap to protect it from shipping damages. Enermax typically includes a variety of accessories in their packages. In this case, besides the normal stuff like screws, a power cord, and the manual, we also get a nice cable tie, a bag for unused cables, and stickers.
The power supply comes is a gunmetal color and has a golden fan grille. The latest trend is for manufacturers to print a large logo on the side of their PSUs, or at least attach a large sticker. The Modu82+ series follows this pattern, with its name printed on the side panel. Users can't normally see this logo after installing the PSU in a case, and now it's not possible to see the label with the PSU specifications without removing the PSU, but nobody seems to care. The specifications label is now on top of the power supply, because users don't read it anyway after the unit is installed in a system. The back of the casing is totally perforated to serve as an exhaust.
The front provides the jacks for the cable management system. There are two large 12-pin red jacks and five 5-pin black jacks. The smaller black jacks are reserved for peripheral components like hard drives and optical drives. The red ones are for the graphics card connectors. Enermax states that the 12-pin jacks are "future ready", as they can release updated cables should the need arise.
You can see in the above image that Enermax trimmed the edges of the opening around the bottom fan. Enermax says this additional angle allows the air to enter the power supply more smoothly and thereby reduce noise levels. Since the fan is already quiet and runs at a very slow speed, we couldn't really notice a difference in acoustic noise.

Horizontal bar charts for price? Really? I guess when all you have is a hammer...Woodchuck2000 - Thursday, March 27, 2008 - link
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.strikeback03 - Tuesday, March 25, 2008 - link
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.
