Enermax Revolution85+ 950w Modular PSU

Cables, Connectors & Internal Layout

Cables, Connectors & Internal Layout
 
Much like its predecessor the Galaxy and many other of Enermax's modular PSU's, the Revolution85+ is hybrid-modular in design. This means that several of the essential cables required to power a basic PC system have been hard wired into the unit. This reduces the chance of poor connections or increased resistance due to an ill fitting modular plugs, but can come at the cost of having additional cables to 'hide' should you be a neat PC freak. As we can see from the images below, the 950w version of the Revolution85+ is fitted with 1x 24-Pin ATX, 2x 6+2Pin PCI-E, 1x EPS12v and 2x 4-Pin P412v connectors.

On the modular side, the Revolution85+ is fitted with a total of 10 connectors: six Black in 5-pin format and the remaining four Red in 10-pin format. Enermax claim that the 10-pin modular connectors will be useful for future changes in hardware, but in all honesty I've yet to see a manufacturer release updated cables for their modular PSU's to support new standards.
 
As you may have already guessed the black connectors positioned nearest the middle of the unit  are a used for powering Molex/SATA devices, while red connectors are used solely for PCI-E graphics cards.

Given the Red + Black colour scheme of the Revolution85+ I would have put money on Enermax updating their cable sleeving with Red weaving instead of the traditional Gold. Unfortunately that's a bet I would have soon lost as Enermax have unfortunately cheaped-out and used the same sleeving as on all of their other units.
 
Another thing which is quite unsightly is the splitting of some of the connectors half way down the cables. It's almost like Enermax initially only designed the unit with a single hard-wired PCI-E and EPS12v connector, but changed their minds as it hit production and decided to bodge things with a cable splicing exercise.

Included in the modular cable bundle is two PCI-E cables that extend out into four 6+2 Pin connectors. This in addition to the hard-wired connectors brings the Revolution85+ 950w PCI-E connector count up to six - perfect for almost all graphics card configurations. However, bearing in mind that the Revolution85+ has four plugs on the PSU side for PCI-E cables, and each cable has two PCI-E plugs, there is the potential to have a whopping TEN PCI-E connectors plugged in at any one time! Now where's my Quin-SLI motherboard got to!

 Molex Connectors Modular 6x
 Floppy Disk Connectors Modular 1x
 SATA Connectors Modular 12x
 PCI-E Connectors Modular 6x 6+2 Pin
  
One final point to note about the modular cables is just how heavily weighted in favour of SATA the Revolution is, with our 950w model kitted out with a whopping 12 SATA plugs spread over 3 cables. This is double the number of Molex connectors on the unit, which seems a somewhat strange decision considering most enthusiasts are unlikely to use more than 2 - 4 SATA connectors in an average PC system.

Moving on to the internal components we can see that Enermax have managed to cram quite a lot of components into a small space. Sitting pretty in the middle of the unit are three beefy transformers (yellow), with the two larger ones responsible for both the +3.3v, +5v and +12v rails. A logical guess would say that each transformer powers three of the six +12v rails, with the remaining +3.3v and +5v rails also being assigned a transformer each. The smaller single transformer is more than likely used solely for powering the +5vSB rail while the unit is in standby. 
 
Enermax Revolution85+ AC Filter Enermax Revolution85+ Shoddyness
 
Although the general arrangement of components inside the unit is quite tidy, the soldering and appearance of some of the hard-wired cables entering the unit is actually quite shabby. As we can see from the image top-right, there is also a large gap around these cables as they enter the unit, possibly indicating that Enermax were either expecting to hard-wire more cables into the unit, or simply didn't make any alterations to their casing design to reflect the small number of hard-wired cables.
 
Rather than going for a separate AC filtering circuit, Enermax have installed an EMI filter as part of the AC plug its self. This should help to keep any internally generated noise from the MOSFET's and other components contained within the device, while also preventing any external AC line noise from entering the PSU.
 
Enermax Revolution85+ Capacitors Enermax Revolution85+ Small Caps
 
Over on the high-voltage side of the unit the three primary capacitors are manufactured in Japan by Panasonic Corporation have been neatly tucked below one of the units black aluminium finned heatsinks .Each of the capacitors carries a specification of 220uF / 400V at a max temperature of 85°C.
 
Moving over to the low voltage side we can se a collection of six much smaller capacitors also manufactured by Panasonic. These carry very few visible markings other than 105c, but have the job of performing one final smoothing of the voltages before they exit the unit and find their way into your PC hardware.

Finally we arrive at the 135mm clear bladed fan manufactured by GlobeFan. This fan is rated at 0.28A when running at 12v and is capable of moving 95.62CFM at a very respectable 28.2dBA according to manufacturer specs.
 
Now that we've got acquainted with the Revolution85+ let's get on to the testing...

Enermax Revolution85+ 950w Modular PSU

Looks like the Corsair 1000w finaly has some competition?

Seems to me this wins on performance but the Corsair wins on quality?

Yeah its a bit of a tough call really. Although the performance of the Corsair HX1000 isn't _quite_ up to the same level as the Revolution, the Corsair is a fair bit cheaper, is more generic in appearance (for those who don't have a red PC) and doesn't have any of the cable issues that the Revolution does.

The cables would be a big thing for me personally, but if you can hide them well in your rig and you want the best PSU you can get then it looks like the Enermax gets that crown.

I think 195 is a little bit more than I'd be prepared to pay for it, considering the little niggles it has. If they corrected those in some sort of a revision, it would definitely be worth it.

Goddam that's brutally expensive. Amazing, but yowsers.

Great to see the hot box really stressing them. And I totally agree about the molex thing. 6 SATA cables is plenty, 8 is overkill (who has 6 HDs?) and 12 is just ridiculous especially when it comes at the cost of molex's which work for pumps and lighting and and and.

(btw, the "discuss in the forums" bit on the last page isn't a link)

Yeah I'm not quite sure what possessed them to put THAT many SATA's on there. Even for server use thats excessive. Most 2/3U rackmount servers cant hold more than 9 disks.

The ideal cable configuration in my opinion is:

2x SATA cables, one with 4 connectors, the other with 2.

4x Molex cables. two with 3 connectors, two with 2 connectors

I think they should just include basic cables, and 2 of each, and you should be able to order custom cables.

or not custom, but select from a larger range, custom lengths etc... would cost alot but worth it

of course this comes out the day after i order my corsair 1000...

although im pretty happy with my decison because i know that the corsair has proven itself

Woah, those Sata's do seem outrageous...

I personally think 3 per cable is just about right, since most caddies hold 3 drives, so it fits rather nicely.

Corsair still get my vote, but nice review Jim

Terrific review so nice to see someone be critical of these PSU's honestly it makes me weep when some reviews are so one sided as have so many of this PSU.

I don't recall any other site retesting a off the shelf model and also I might be wrong but no other review picked up on the Sata Molex issue.

Thank goodness that there is somewhere we can come to get a totally unbiased review of what is really just a very good PSU, not a world beating machine that will run for the next millenium and only use 10 pence of electricity like some other sites might try to have us believe.

Thank you for the BEST review of this PSU I've ever seen and I think I "might" have read 98% of them.

Cheers for the feedback everyone. KimandSally I'll slip you that 20 next time I see ya lol

Fingers crossed they get the issues sorted. The Galaxy went through a few revisions in its time, so at least Enermax don't seem to be the kind of company to bosh out a product and then put their fingers in their ears until it goes EOL.

I'm quite surprised nowhere else picked up on these things though. Even tho I'm a picky git sometimes, these things were so glaringly obvious.
