Modu82+ Internals Continued



The PCB with the jacks for the cable management system shows a clear distribution of the different rails. One 12V rail connects directly to three pins of each graphics card connector. The other 12V rail distributes to the other three pins of the two graphics card connectors as well as the peripheral connectors.







The secondary side shows the cable distribution to the cable management PCB and the fixed cable harnesses. Here we see the three 12V rails, each with a different colored shrinking hose attached at the end. Each of the 12V cables outside of the PSU also has a color marking besides the basic yellow color. The rest of the capacitors are stuck behind the cables and manufactured by Nippon Chemi-Con. It looks a little bit messy in between these capacitors, which will definitely not help with airflow and therefore temperatures may be a bit higher. However, all these capacitors are rated at 105°C, which is actually quite normal. There are also lumps of glue applied in between the capacitors, which doesn't leave a good impression.





The fan is controlled with a PWM circuit, just as we see with modern CPU coolers for example. The fact that the fan is detachable is nice for those users that might want to change it. We have experienced enough PSU fan failures (or increased noise from failing bearings over time) that it makes sense to allow for an easy replacement of the PSU fan.

    Maybe it's only my impression, but isn't the choke wire outside of the PCB hole?

    "...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. Reply

    The article misses important pictures, including Voltage Distribution and efficiency graphs. Reply

    So maybe you should read it more carefully... Reply

    hope u do that fast as i want all corsair 4nd 5 series psu to be there...especially that 450vx with other good psus Reply

    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.

    Correct and we are working on that kind of article already :) Reply

    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.
