"...there are two main capacitors..."
And who is the Mfgr of these for the Modu82+ series? Should I assume Hitachi as stated for the Pro82+ series?
Are you sure there are three rails, what does the bottom of the main PCB look like? Photos please.
According to your diagram the Modu82+ 525W has no floppy connector, Enermax specs state otherwise.
"The solder joints in general aren't that great with Enermax,..."
Really? Photos please.
Regarding Detailed Voltage Distrubtion , Efficiency & Acoustic Comparison: What were the results for the Modu82+ 525W?
Did OCP perform correctly?
How was crossload performance?
How did you test these PSU's?
you guys need to get out into the real world and take a break if you have been anxiously awaiting, for months, the arrival of boxes that pump electrons.
Due to marketing with higher and higher wattage PSU's, a lot of people still are clueless on how much a modern day system uses (or at least i am). So i was wondering of Anandtech can give typical systems in which would use said PSUs can be used safely and to maximize efficiency.
Such as mention that a dual core, 9600GT system using the 385? Or a 8800GT + quad core using the higher ups? Or can a 385 watt PSU (being that its enermax) handle say a 8800GT + quad core? I remember many websites in the past stating that even well to do gaming system don't need as much watts as people would expect.
If the vast majority of power can be served on the 12V rails, then yes.
an 8800GT less than 100W at full power. You can be fairly certain that the rest of your system pulls less than your graphics card (at least if it's core duo...havne't looked into quad cores).
When you go to PSU calculators, those figures they recommend are based on everything in your system operating at 100%. maybe it's just me, but I've never had my GPU, CPU, HD and DVD all going at 100% at the same time. At idle, you're probably pulling under 100W with an 8800GT (512mb). If you're overclocking, it can vary.
The main key is to get a good PSU, not necessarily a huge one, though I'm building one for my parents that's got a huge PSU (i've i'd seen this review 4 days ago, I would have bought the 385W enermax), because it was rated as very quiet....but these are apparently even quieter...and more efficient too.
lot of places just focus on 800 and 1000 watt psu's
i'm looking at the conclusion page and it says 350, 380, 385 !!!
i don't upgrade everytime something new comes out so these power supplies are still very usable for me and im glad they get some attention.
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?
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.

Maybe it's only my impression, but isn't the choke wire outside of the PCB hole?http://www.oink.wz.cz/mimo.jpg">http://www.oink.wz.cz/mimo.jpg

hope u do that fast as i want all corsair 4nd 5 series psu to be there...especially that 450vx with other good psusfeelingshorter - Wednesday, March 26, 2008 - link
