Package Contents and Specifications


As with the former Pro82+, the Pro87+ again omits cable management. This means that all of the cables are attached to the power supplies and you will not be able to remove any of them. In the package you will find a power cord, cable straps, a sticker, screws, the CordGuard™ and the manual in many different languages. The packages come with tons of explanations and information to show you why this power supply is better than the competition. It's a little too much if you ask us, but at least you have something to read once you spot one of these packages on the shelves of your local dealer.


The Modu87+ is the cable management version and comes with detached cables and a nice pouch to store unused cables. Additionally you get a power cord, screws, the CordGuard, a sticker, cable straps, and a manual.

Specifications







The internal structure is the same in both series; you will find the exact same PCB and components in a 500W Modu87+ as in a Pro87+. All of the different wattages come with the same three 12V rails of 25A; the difference is in the total combined power. Don't assume you can pull the same amount out of the different models, because there are other limitations that make this impossible. Specifically, some of the capacitors are smaller on the lower wattage models. Also worth note is that with only 20A to 24A on the 3.3V and 5V rails, Enermax follows the trend of modern systems that need less from these rails than older systems.

    I'm sure you're room temp isnt 50 degrees celsius... (122f)

    Sorry guys, didnt see you actually put it in an environment at 50c. (should read better before commenting)

    Just curious why you picked such a high temp to test. Do you find that there are cases this warm in rooms with no A/C?

    It's a stress test to simulate a hotter case; if a PSU can handle 50C, it can easily handle the more common 30-35C. Reply

    Could you hook up some different power supplies and show the difference they draw from the wall versus these at idle and load with a basic quad core, 4GB ram, two hard drive, and 5870 setup? I'm curious if spending $50 more on a power supply is going to actually make that big of a difference over a year of computing cost wise for electricity. Reply

    In most cases it's better to keep your current PSU rather than buy a new one. Sometimes if you have a very inefficient unit it's worth the upgrade. If you already have a plain jane 80plus PSU, then it would be a waste of cash to upgrade.

    For instance lets say your PC idles at 100w DC from the board. We will use a 500w power supply for an example.

    Your plain jane 500w 80plus PSU idles at 80% efficiency and the fancy gold one idles at 87% efficiency. If you calculate it to the wall for the plain jane 100w/.8= 125w, the gold one is 100w/.87= ~115w. So we have a difference of 10w. If we calculate the idle power difference over a year at .10 per kwh then: ((10w*24*365)/1000) * .10 = $8.76 saved per year with your PC on 24/7.

    If you bought a 500w gold unit say at newegg for $100 just to upgrade (and the braggin' rights) it would take you over 11 years to recoup your $100 idling your PC 24/7. I can see many peeps will proudly display their gold unit signature. :) Let's see if they keep their PSU for 10 + years!

    If you were going for a new build and trying to decide whether to go for a plain jane 80 plus at $50 or the fancy gold one at $100 (for a difference of $50) it would take over 5 1/2 years to recoup your $50 idling 24/7. For some this might be reasonable depending on the price of electricity in their area, and how much they actually use their PC. If you don't use your PC a whole lot, the plain jane 80 plus will most likely be good enough.

    Don't forget the extra heat needs to be cooled during summers.
    But I agree, the savings is small especially since most people don't idle 24/7.

    Who pays $0.10 per kwh? Is that residential? I'm in NYC and pay ~$0.20. Reply

    Upgrade only if you have issues:
    *the air blown by the PSU is too hot
    *computer is finicky (bad quality PSU could be the reason)
    *you (actually) need more wattage
    *your PSU is noisy, and you want a silent one

    As seen in the page, one of those expensive PSU will happily provide you 15% or more power above nominal (no mention of the efficiency though, but it should probably be higher than 80%), while a low quality power supply might give you out-of-range voltages when reaching 90% load (or maybe even less than that)

    And not to mention that the fabrication of the PSU also consumes energy. If you throw away ur old 80% PSU that is still working to buy this one you are actually wasting energy. It's the same with cars. Manufacturing of a car (creating the steel, plasitics,...) consumes more energy than it will ever use while it's actually running. So trading in your old one for a new one is wasting energy.

    Main reason to buy this PSU is because of low noise. Efficient = less heat = lower fan speed = quieter. Simple.

    I also would like to see a PSU round up maybe in march time frame... :)

    I'm still sitting pretty with my Enermax Infinity 720 Watts right now, and you do make a good poing about Enermax PSU prices not dropping much.
