Enermax Modu87+ 700w PSU Review

The ultra bright fan, from the inside. Notice the unit hasn't been totally sprayed inside.

The Twister fan, uses patented ‘twister bearing technology' which keeps noise levels to a minimum (more on that later), and it also helps to increase the life span with Enermax rating it at 100,000 hours. Most fans are rated between 30,000 and 50,000 hours. The Rotor has an integrated magnet which ensures a frictionless and smooth motion. The bearing sleeve is self lubricating with abrasion protection. The fan also spins for 30-60 seconds after the unit has been shut down to help remove excess heat from the system – Enermax call this ‘HeatGuard'.

The insides are rather unusual, we are not sure if we have seen a PSU with heatsinks all coloured blue. Its certainly eye catching!

AC Filtering starts from this area and the vertical board in the image above is home to four Y capacitors, one X capacitor and a coil.

Two VRMs which handle the 5V and 3.3 V rails.

Enermax have implemented the ‘Dynamic Resonant Transformer Array”. This is based on the highly efficient resonant topology which has been used in LCD monitors. On this PCB there is an additional resonant choke. By using this design zero voltage switching of the main switches is achieved which results in dramatically lower switching loss with boosted efficiency throughout.

We have seen the controllers before on the Seasonic X series supplies. They are the CM6901 and a CM6502 for the PFC section. You can also see the primary capacitor above, a high quality Rubycon.

The electrolytics are Nippon Chemi-Con and the polymers are Enesol branded. VRM's are handled by the APW7073A control processor.

The sleeving is excellent, going into the unit which helps stop any damage to the cabling against the grommet.

  1. I have this power supply. I got it on sale for £120 locally. I love it. As you say wouldn’t even know its on.

  2. That gold fan is intense. Not sure if I like it or not. I might need to get a pair of baggy jeans, and a gold tooth and maybe a baseball cap on backwards and start rapping.

    Great results though, dont think ive ever seen a PSU score 90% in efficiency across such a broad range.

  3. Amazing to see such high efficiency levels. They dont make them now like they used to, when 80% was an achievement.

  4. Enermax are quality, I noticed some soldering issues on a few of their last range myself, but they seem better now. technically very well created supplies, good all round.

  5. Great unit indeed, some brilliant results in your testing. Its a tad on the expensive side though, especially with such good competition lately from Thermaltake and Antec. still recommended though.

  6. Great review that is a hell of a PSU, bit costly but probably worth it.

  7. thats a great review and I like the looks, its very bling, would look good with some case lighting bouncing off it !

  8. I dont think we really hear of any issues with Enermax, I would say with corsair right now they are the best.

  9. Enermax make quality products, looking forward to seeing some info on their new fans too.

  10. It really is too much cash though, 150 here can get me a 900w PSU or more. its great etc but its quite expensive.

  11. Its only expensive if you dont value the quality. there is quite a lot of internal progress with this range, the efficiency levels are very very high.

  12. I need a new power supply but I will probably go for the 775W thermaltake you guys reviewed weeks ago, its £50 less. I like quality but I also need to eat 🙂

  13. quite funny, I was looking for a review of this and went onto google, not coming to the site this morning as I usually do. First in the google search ! I laughed.

    Anyway, nice PSU, great results, but I need to work out if I can afford to buy it this month now.

  14. this is very good testing, the 12v rail performance is exceptional, I like this a lot. I shall buy one next payday. thank you very much

  15. awesome review KG. efficiency is very high which I like to see, as my electic bill is already mental.
