Enermax Gold: Modu87+ and Pro87+

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.

You're too focused on price only. A PSU isn't something you buy every day. Better to get a great, efficient unit that has headroom to grow and will last you many years, even if it costs a little more.And yes, fifty bucks is a little more. Most people on Anandtech wouldn't whine if they have to pay $200 for a video card, and we all know how fast they go obsolete. Get some perspective here please.
The PSU is arguably THE most important piece of equipment in your whole PC. If it doesn't function well, nothing else will either. So there's nothing wrong with buying one of the best units out there, quite the opposite.

Actually this is more like a $600-700 videocard amongst PSUs. Most will be happy enough with a HD5870. Many PSUs in the $100 range, like the HX620, are damn good. However like any other computer component, those extra 5% costs just as much as the first 95%.Spacecomber - Tuesday, January 19, 2010 - link
I happy to see another P/S review on Anandtech. I don't think that there have been any in quite a while. While these Enermax models are very nice, the price probably makes them impractical for any builds that I can imagine.However, one thing that I really like about these power supplies is their very low noise output. As I move away from building game-centric computers to computers that are likely to be used more as media servers, keeping the noise down to being virtually inaudiable becomes more important to me (especially for a music server). For these kind of computers I don't need a huge amount of power, and therefore I'm not looking to invest a huge amount of money in the P/S. I'm really looking for a power supply that can give me the quietest experience for the least amount of money. (To get a really quiet P/S, I accept that I'll be spending more than one would expect to spend on most "budget" power supplies.)
Anyway, this is just a suggestion that perhaps others are also looking for something more like this for their living rooms, instead of a kilowatt P/S to drive an overclocked quad core monster with multiple video cards.

The first three graphs on p.11 look like they need more labeling. Looks like you need to show which PSU for efficiency.mariush - Wednesday, January 20, 2010 - link
On page 10, I somehow doubt the readings were made at 50C room temperature (see chart headers)JarredWalton - Thursday, January 21, 2010 - link
As mentioned below, the tested was done in a temperature controlled chamber, so the ambient temp was indeed 50C. I would update the graphs, but Christoph custom-made these charts so I'll leave that to him. :)JarredWalton - Tuesday, January 19, 2010 - link
Fixed... the same graph was initially inserted on all three as you may have noticed.markshin - Saturday, July 24, 2010 - link
i bought a Modu87+ 700W, because i needed a new psu to replace my 5-year old 70% efficient unit..I don't intend to run this at 100% load, that's sheer madness. 30-60% is the sweet spot for today's PSU's, that's where they are most efficient.
and also, they're selling for about US$150 (at least from where I'm located).

Hi Chris,Thanks for the great review. Any chance you can update the results to include the new, 800W and 900W models they've just released? I'd love to see if those also stay silent at all loads.
